A4 Stainless Steel Pins, Clips and Rivets

R Clips, also known as R Keys, R Pins or Hitch Pins. Often used to secure ends of round shafts such as clevis pins or axles. Re-usable and made from A2 grade stainless steel, they can be viewed as a better option than split pins as they are easier to remove whilst essentially doing the same job.

Spring cotter pins, also known as R clips with a double loop. The extra loop gives more flexibility than the regular cotter pin, making them easier to use and adjust. Often used to secure ends of round shafts such as clevis pins or axles. They are re-usable and are easier to remove than split pins. Made from A2 (304) stainless steel, they are suitable for marine and outdoor applications, such as securing canopy frames and other ship deck mounted items. Conforms to DIN 11024.

Clevis Pins are used to allow rotation between connected parts about the Axis of the pin. Our Clevis Pins are unthreaded and consist of a head section, shanked body and a drilled hole across the shank. Used in conjunction with split pins or cotter pins to fix the Clevis in place. Uses include Agricultural Machinery, Towing, Sailing and Linkages. All dimensions are approximate.

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.

Cotter rings, also known as split cotter rings, kick-out rings and retaining rings. These are made from A4 marine grade stainless steel and are durable and corrosion resistant. Designed for attaching and securing items and for use with clevis pins. They are easily removable and fast to install. Insert the end outside the circle into a hole on the item it's attaching to and wind it on.

Linch pins, also known as lynch pins. Strong and durable A4 stainless steel ring used for mooring ropes and chains, diving gear and saddlery. Also referred to as linch pins with O ring.

Blind rivet nuts with a flat head, a straight knurled shank and an open end. Rivet nuts are also known as blind nuts, rivnuts and nutserts. For use with sheet metals and thin gauge metal parts, such as panels, castings and tubes. Rivet nuts are installed using a rivet nut gun, which compresses the thinner walled part, making it push out to form a collar. The knurling/serrations is there to grip the rivet nut and stop is spinning. Rivet nuts, like rivets are installed from one side, which is useful when there is no back access. An open ended rivet nut allows for a longer screw to pass through the nut, making it more vibration resistant. The tightening torque specifications are guide values depending on the material of the original component and must be checked by testing the component.

The countersunk head on these rivet nuts offer a flush, non-interfering fit when installed into a suitable countersunk hole. As with the flat head, the countersunk head can be used to clamp a single or multiple sheets of materials. The knurling on the body helps the rivet nut grip the connecting surface and help to prevent it turning. The open ends allows the rivet nut to be used with longer lengths of bolts. Used in a multitude of industries such as aerospace, automotive, rail, HVAC, white goods, electronics, DIY and general engineering.

Low countersunk rivet nuts are a specialised version of the countersunk head. With their reduced head height, it gives an almost flush finish where a non-interference fit is not critical. It can be set without the need to produce a countersunk hole and therefore can be more cost effective. The low countersunk height is ideal for very thin gauge sheet materials and when clamping thin single sheets. The knurling helps the nut to grip to the adjoining surface. The open ends allows the rivet nut to be used with longer lengths of bolts. Used in a multitude of industries such as aerospace, automotive, rail, HVAC, white goods, electronics, DIY and general engineering.
