Slotted Spring Pins can also be known as Sellock Pins or Tension Pins.

Slotted Spring Pins are simply a single coil of steel with an open slot, this will enable the pin
to reduce its diameter, so that it can be easily inserted into the appropriate size hole. The
most common form of Spring Pin is the Heavy Duty type, DIN 1481/ISO 8752.

These pins are always listed by the hole size they are fitting in to.

We carry large stocks of these Pins, available for same day dispatch.

A Split Cotter Pin is a simple fastening device to prevent parts being released off the end of a shaft. Alternatively, they can be very useful to prevent nuts coming undone off a threaded fastener by simply drilling through nut and bolt. The o/d of the pin is made marginally smaller than the hole size to give easy fit. Once inserted the legs are bent over in opposite directions to complete the fastening.

What is the difference between a Shim Washer and a Flat Washer?

Even though Shim Washers can look very similar to Flat Washers and sometimes have the same dimensions, there is a difference in their purpose/usage.

Flat Washers are mainly used for load distribution, fastening and surface protection especially with screws, nuts & bolts. Whereas Shim Washers are widely used as space fillers or gap alignment. Shim Washers are also more precision made, with tighter tolerances.

Shim Washers also have various available thicknesses with the same inside diameter and outside diameter. For example, 8mm x 14mm has thicknesses available of 0.1mm, 0.2mm, 0.3mm, 0.5mm and 1mm.
