Self Clinching Studs

Product Info

The self clinching stud is a threaded fastener or plain pin which incorporates a specially formed platform and combined locking ring under the head. When pressed into sheet material the platform displaces some material into the locking ring, thereby securing the fastener in place. This results in a high torque and push out resistant fixing.

Self Clinching Studs come in two basic types Flush Head where the embedded head is flush with the face of the material and Non Flush Head where a larger non flush fitting head is used. The latter is used in high strength applications which require improved pull through resistance. e.g. if used in substitution for a weld bolt.

Materials & Finishes


The standard studs are manufactured from heat treated carbon steel and are supplied with a bright zinc and clear passivated finish. A chromate passivated finish can also be supplied.

Studs manufactured using 300 Series Stainless Steel are supplied for use in Aluminium Sheets and are supplied in the self colour finish.

Studs for use in Stainless Steel Sheets


Where studs are required for installation into stainless steel sheets of 92 HRB or less then our 400 Series Stainless Steel Studs should be used. These studs have been specially hardened and are supplied self colour and passivated to ASTM A380 condition. Corrosion resistance of these studs is equivalent to zinc plated steel.

Applications


Self clinching studs are easily assembled with any squeeze press and can be used as a suitable alternative to replace capacitor discharge studs and weld bolts at lower installation costs.

Stock Sizes


From M3 to M10 in metric threads and imperial threads to suit your requirements. From 3mm to 10mm in metric diameters and imperial sizes to suit your requirements.

Installation


Flush head self clinching studs are easily assembled with any squeeze action press using a flat faced punch and die with sufficient pressure to embed the head into the surface of the sheet material. The force required is variable depending on the size of stud and sheet material being used, excessive force should be avoided.

Hole Size and Preparation


For proper fixing it is recommended that the holes are punched into the sheet material rather than drilled, however drilled holes may be used. In either case it is essential that the holes must be cleanly prepared and free from all burrs.
