A4 Stainless Steel Pins, Clips and Rivets

Fastener Material Key
A1	A1 Stainless Steel - Also known as grade 303. A general purpose grade of stainless steel but with better fabrication/machining properties than grade 304.
A2	A2 Stainless Steel - Also known as grade 304 or 18/8. A general purpose grade of stainless steel.
A4	A4 Stainless Steel - Also known as grade 316 or 18/8/3. A higher corrosion resistant, marine grade of stainless steel.
Alum Blk	Black Coated Aluminium - Black coated lightweight aluminium, with a steel mandrill.
Alum Pln	Plain Aluminium - Typically for blind rivets, plain, unpainted lightweight aluminium, with a steel mandrill.
Alum Wht	White Coated Aluminium - White coated lightweight aluminium, with a steel mandrill.
Copper	Copper Alloy - Copper has good corrosion resistance and high tensile strength, allowing it to withstand high-pressure and high temperature conditions. It is a highly ductile and malleable material, enabling copper washers to create tighter seals and withstand vibration better than steel. Copper also provides excellent thermal and electrical conductivity.
SS301	301 Stainless Steel - More elastic stainless steel grade used for springs and parts that require some higher strength.

Cotter Split Pins (DIN 94) in A4 Stainless Steel

Cotter Pins, also known as Split Pins are designed to be inserted through a hole and bent to secure in place, they are commonly made from wire which is semi-circular in cross section and square cut at the end, other specialist end finishes include Mitre or Bevel. Lengths are measured from the end of the tines to the point the base of the eyelet hole contacts with the host material. An unthreaded fastener solution for single use, as bending fatigue can cause failure if re-used.
