Spring Tension / Seloc Pins

Mild steel and stainless steel heavy duty slotted spring tension pins. Also known as seloc / sellock, bissell & roll pins. ISO 8752. These pins are oversized to be driven into holes of the diameters listed. Spring pins are a very reliable low cost fastening system, which is particularly suitable for large volume production which secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the hole diameter, and a chamfer on either one or both ends to facilitate starting the pin into the hole. The spring action of the pin allows it to compress as it assumes the diameter of the hole. The radial force exerted by the pin against the hole wall retains it in the hole, therefore a spring pin is considered a self retaining fastener. Spring pins are designed for use in double shear applications.
