Taptite thread forming screwsMechanical properties according to ISO 7085:1999.

When tapping the neccessary force required is always less than the tensile strength of the screw.

The size of the mounting hole, precision, material properties and lubrication method affects the tapping torque.

The pull-through strength value in the following chart is an directional value, not a constant value set by the ISO standard.

Case hardened self-tapping screws has to be marked with a “-0-” marking.The mark is mandatory in socket and hex head screws with nominal diameter M5 or larger.If separately requested, this mark can also be put in smaller or different types of screws.

Press-in fasteners can be used to create, either internal or external threaded joints on sheet metal. These joining ele-ments are securely clinched to the host material.

The joints can be used to attach and detach objects several times with a screw or a nut. This feature allows the improve-ment of manufacturing efficiency and the production of com-plex sheet metal solutions, such as closed corner products.

There are two types of press-in fasteners, SELF-BROACHING and SELF-CLINCHING based fasteners. Both types are in-stalled to a drilled or punched mount hole in the host mate-rial, by applying a constant squeezing force.

Fasteners for sheet metal

83


Self-broaching fasteners

A fastener is attached to a mount hole and is pressed from the opposite side, so that the bottom face of the fastener clinches to the host material. The serrated clinching ring in the shank of the fastener provides torque resistance, which prevents any turning between the host material and the fastener. This type of fastener suits well for thin and hard materials.

Self-clinching fasteners

Fasteners with a hexagon head or serrated clinching ring are attached to the host material in a mount hole. The bot-tom face of the fastener is designed to displace the host material causing it to flow into the thread or groove of the fastener, thus locking the fastener securely to the host material. This type of fastener suits especially for sheet metals of medium hardness with minimum thickness of 0.8 mm, as well as for softer materials.

More specified information about the properties and benefits of an individual fastener can be found from the product page.

WEARB and WEARBSOWEARB and WEARBSO are internal threaded self-broaching nuts with a serrated shank. When installed the shank rivets around the hole, while the serrated part clinches itself firmly to the host material, ensuring a strong and enduring joint.

WEMINARBWEAMINARB is a miniaturized WEARB. It is especially designed for spots with limited space to operate.

WEMINLOKWEMINKLOK includes the properties of WEMINARB. The last few leads of the nut are distorted in order to give the nut the ability to lock attached fastener, making it resistive to working and vibration loosening.

WES and WECLSWES and WECLS are self-clinching flush nuts, which are installed into a mount hole and locks in place by shaping the host material causing the displaced material to flow to the serrated ring at the bottom face of the fastener.

WEFH and WEFHSWEFH and WEFHS are self-clinching studs that are installed into a mount hole and lock in place by shaping the host material causing the displaced material to flow smoothly and evenly into the groove and around the ribs.

WEHFHWEHFH is a self-clinching stud, which is installed into a mount hole and lock in place by shaping the host mate-rial causing the displaced material to flow smoothly and evenly into the groove and around the ribs.

WEFWEF is a self-clinching flush nut, which allows level surface on both sides of the host material. When installed the hexagonal head embeds into the base material causing the displaced material to flow into the groove, thus locking the fastener to the host material.

WEBSO and WESOWEBSO and WESO are self-clinching standoffs, which allows fastening in different distances from the host mate-rial. When installed, the hexagonal head embeds into the host material causing the displaced material to flow into the clinching groove.

Self-clinching nut

Self-clinching nuts WES and WECLS are internal threaded join-ing elements, which are installed to a sheet metal by pressing.

The bottom face of the nut contains a serrated ring and a groove, that when applied steady squeezing force, causes the host material to steadily flow into the groove, creating strong and enduring joining.

Benefits• High torque resistance• Level opposite side of the joining• Small and clean joining• Easy to install by clamping



Sheet metal material

Sheet metal material hardness must be less than 80 Rb (150 VPN). Stainless steel sheet metal material hardness must be less than 70 Rb (128 VPN).

Sheet metal thickness

Self-clinching nuts and standoffs can always be installed from thickness of 0.8 mm onwards, (M2-M5) depending on the size of the shank. See the chart on the next page.

Shank selection

Always select the longest possible shank to ensure the strongest possible joining.

Installation direction

Fastener installation to the joint is always recommend-

ed to be done from the opposite side of the head.

Self-clinching studSelf-clinching studs WEFH and WEFHS are external threaded joining elements, which are installed in to the sheet metal by pressing.

The ribs and the groove at the bottom face of the stud shape the host material creating a strong and enduring joining.

Benefits• Easy to install by pressing• High torque resistance• Clean joining• Level opposite side of the joining

When installed, apply squeezing force sufficiently enough to achieve a steady embedment of the head. Using excess force must be avoided. Installation squeezing force varies depend-ing on the material of the sheet and the size of the fastener. See page 104 for more information.

Noteworthy

In particular installation combinations depending on the size of the fastener and the thickness of the sheet metal, the anvil must be equipped with a countersink. Countersink is needed for self-clinching studs M5 or less when installed in to a sheet with thickness 1.5 mm or less. Self-clinching nuts M6 or larger also require a countersink, when the sheet thickness is 2.5 mm or less.


The sheet metal material hardness must be less than 80 Rb (150 VPN).Stainless steel sheet hardness must be less than 70 Rb (128 VPN).

Mount hole

Holes can be made by punching or drilling with -0.00 / +0.08 mm tolerance.

High strength studsWEHFH high strength stud is designed for joints requiring stronger joining, and where level embedment isn’t neccessary.

Benefits • Easy to install by pressing• High torque resistance• Clean and strong joining

Mount hole

It is recommended to create the mount hole by punching, even though a drilled mount hole is sufficient. The mount hole has to be clear of any metal shavings and the holes edges must not be too chamfered or rough.

Installation

The installation has to be made by applying steady squeezing force until in the right depth. See page 104 for more information.


The anvil countersink must be used as follows:

Thread MaterialM4 0.80 - 1.19M5 0.90 - 1.29M6 1.00 - 1.49M8 1.50 - 1.99


Sheet metal material hardness needs to be less than 80 Rb (150 VPN).

Self-clinching flush nutWEF self-clinching flush nut is designed to create level sheet sur-face on both sides of the joint.

When the nut is clamped it embeds itself in to the sheet by dis-placing the host material causing the material to flow into the groove, thus forming a strong and enduring joint.

Benefits• Allows the creation of a joint in places with limited space• Easy to install• High torque resistance• High push-out force resistance• Level surface on both sides of the joint.

Mount hole

The mount hole tolerance has to be -0.00... + 0.08 mm

Sheet metal hardness

Stainless steel sheet hardness needs to be less than 70 Rb (128 VPN).

Installation

Installation has to be always done by applying constant squeezing force, never by stamping.


See the chart on the next page.

Shank

It is recommended to use longest possible shank length that the sheet metal thickness allows. This creates the strongest possible joint.

Installation sideInstallation to the joint is always recommended to be done from the opposite side of the head (round face in this case).

KALEI clinch nutThe KALEI clinch nut is installed manually or by clamping into a drilled or punched mount hole.

The shank of the nut has been rifled in order to ensure much higher torque resistance in the joint.

The KALEI clinch nut is precision made and suits for automatic feeding.

Manual hand tool:KALEI hand tool is needed for manual installation.

Clamp:A simple clamp and feeding device can be used in mass production.

Rivet nuts

Tools are important when using rivet nuts. They are strong and easy to use. The nosepiece and cap screw are easy to replace. A single tool suits for the installation of various sizes. Easy to use manual, pneumatic and hydraulic tools are available for use. The rivet nuts are placed into drilled or punched mount holes. The rivet nut is then placed into the nosepiece manually or automatically, depending on the type of the tool. When the jaw pusher is drawn out the non-threaded part of the nut expands radially, thus riveting the nut into the material. Turning the cap screw counter-clockwise releases the tool from the nut.

When the material is thin, using rivet nuts is a simple and ideal way of creating a threaded joint.

The rivet nut suits well for materials with thickness of 0.25 to 8.00 mm.

Available in different materials: Steel, aluminium and stainless steel.

Thread range: M3 – M12

Shank models

Round:Most common when using normal load on a steel sheet.

Round, Rifled:Grants higher torque resistance.

Hexagon:Grants the highest torque resistance with high loads.

Head models

Pan head:Most common when joint surface isn’t required to be level.

Flat head:Used when the joint surface needs to be level.

Reduced Head:Used when the joint surface needs to be level with the sheet metal.

Thru-holed or blind model

Thru-holed:Most common when an efficient and strong penetrating internal thread, without the need for sealing, is required.

Blind:Grants liquid proof sealing, which protects the joint from corrosion or dirt. Important when the joint is painted and the thread isn’t protected.
