SPRING PINS

A spring pin is a very reliable low cost fastening system, which is particularly suitable for large volume production.

It is used in huge quantities, in countless applications, and in widely ranging industries from automobile production to electronics.

A slotted spring pin is a cylindrical slotted pin of hardened spring steel which is accurately made to a diameter greater than the drilled hole into which it is pressed. It is simply driven in and retained by continuous outward spring pressure throughout the full length of the hole. The purpose of the slot in the pin is to allow compression when inserted in the hole.

The outward spring forces act positively in preventing loosening by vibration. The forces required to dislodge a pin from an assembly are great, and there is little danger of vibration shifting the pin. Due to the flexibility in the spring design, spring pins are excellent in shock load situations, and avoid the problems of solid pins which may fracture or cause damage to the other components of an assembly through their rigidity. Spring pins are very light and exceptionally strong due to the material and heat treatment used.

Apart from the low basic cost, spring pins offer vastly reduced assembly times. Only a plain drilled hole is required to normal drilling tolerances. There is no need for any reaming, threading or counter-boring. The pins are easy to insert, either by hand or by automated assembly. No special skills are required, assembly can be carried out quite safely with unskilled labour. Spring pins can be removed using a driver, however they should preferably be fitted in to a through hole, it is very difficult to remove spring pins from a blind hole.
