R-Clips (Euro Pattern) in A2 Stainless Steel

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 R-Clips, Double Ring in A2 Stainless Steel

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 in A4 Stainless Steel

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 Split Pins (DIN 94) in A2 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.

Cotter Ring in A4 Stainless Steel

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 in A4 Stainless Steel

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.

Dowel Pin with m6 Fit DIN 7 in A1 Stainless Steel

Dowel Pins or Parallel Pins are short cylindrical sections of metal used for precise alignment of machine parts and mould tools. They are often also used as reference points for mechanical engineers to ensure repeatable and accurate assemblies. The diameter of these parts is produced to a specific tolerance so that the desired fit can be acheived with a suitably sized and toleranced hole. In this case the ISO fit code is m6.

Blind Rivets with Pan or Dome Head to ISO 15983 in A2 Stainless Steel

Blind rivets, also known as pop rivets, are an unthreaded fastener, and can be used when access is only available on one side of the workpiece or joint. These rivets are fitted using one of several types of riveting tool. These items are manufactured in many different types and material combinations. The examples here are the standard open type, with a domed or pan head, and are to the ISO 15983 standard, unless stated otherwise.

Blind Rivets with Countersunk Head to ISO 15984 in A2 Stainless Steel

Blind rivets, also known as pop rivets, are an unthreaded fastener, and can be used when access is only available on one side of the workpiece or joint. These rivets are fitted using one of several types of riveting tool. These items are manufactured in many different types and material combinations. The examples here are the standard open type, with a countersunk head, and are to ISO 15984 standard.

Blind Rivets with Pan or Dome Head to DIN 7337 in Black Coated Aluminium

Blind rivets, also known as pop rivets, are an unthreaded fastener, and can be used when access is only available on one side of the workpiece or joint. These rivets are fitted using one of several types of riveting tool. These items are manufactured in many different types and material combinations. The examples here are the standard open type, with a domed or pan head, and are to the DIN 7337 standard.

Blind Rivets with Countersunk Head to DIN 7337 in Plain Aluminium

Blind rivets, also known as pop rivets, are an unthreaded fastener, and can be used when access is only available on one side of the workpiece or joint. These rivets are fitted using one of several types of riveting tool. These items are manufactured in many different types and material combinations. The examples here are the standard open type, with a countersunk head, and are to the DIN 7337 standard.

Rivet Nut Knurled with Flat Head, Open Type in A2 Stainless Steel

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.

Rivet Nut Knurled with Reduced Countersunk Head, Open Type in A2 Stainless Steel

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.

Slotted Roll Pins to ISO 8752 / DIN 1481 in 301 Stainless Steel

Slotted roll pins are a heavy duty type of self retaining pin, where the spring steel they are made from allows the pin to sit in tension within the hole that they are fitted into. Slotted roll pins are also known as slotted spring pins, tension pins, split dowel pins and hollow spring pins. Conform to ISO 8752 / DIN 1481.

Spiral Roll Pins to ISO 8750 in 301 Stainless Steel

Spiral roll pins are similar to the slotted roll pin, but are constructed from a spiral of steel, forming a tube shape. These are stronger than the single coil of the rolled slotted pin, exerting pressure more evenly around it circumference, which helps to absorb vibrations better. These are also known as coiled spring pins and conform to ISO 8750.

External Circlips to DIN 471 in Stainless Steel (1.4122)

External circlips are also known as retaining rings for shafts or C-clips. Made from spring or stainless steel, circlips are clipped into place using specific circlip pliers or a taper. On a shaft, circlips are used to lock components such as gears, pulleys and bearings into place. These circlips are designed to fit into a groove cut to a specific size on a shaft.

Internal Circlips to DIN 472 in Stainless Steel (1.4122)

Internal circlips are also known as retaining rings for bores. Made from spring or stainless steel, internal circlips are used to retain components such as bearings into place within the bore. Internal circlips are located into a groove of a certain depth within the bore hole.
