Pinstructure Ltd

Pinstructure oversees the manufacture and distribution of fastener components by working with trusted global manufacturers. An SME family-run business based in Redditch, Worcestershire started in the 1980s.

Our production capacity includes high volume bespoke production as well as smaller volume. With a varied customer base comprising of individual start-ups to some of the larger multinational firms across a range of industries including Formula 1 motor racing, wind farms, agriculture, nuclear power, rail and the marine sector. 

Embracing innovation and diversifying complement where we excel best: quality and technical expertise. Maintaining quality standards is of the utmost importance – Pinstructure is accredited to ISO9001:2008 standard and is now in the process of working towards ISO9001:2015 certification

Our full range can be seen here. Our technical sales team are on hand to help!

In 2010 we formed a new division called Abbey Clamps strategically set up to focus and develop on Hose Clips and Clamps, which had long been a part of our range and had seen consistent growth.

Dowel Pins

Dowel pins are a traditional method of locating and retaining two or more components in an assembly into fixed positions. Dowel pins are reusable and are accurately made to fulfil their needs.

Our range of dowel pins includes:

  • Chamfer both ends
  • Chamfer one end and domed at the other
  • Crown one end and domed at the other

They are manufactured to BS, ISO and DIN standard specifications including BS1804 grade 1 & 2, ISO 8734A, ISO 8734B, ISO 2338B, ISO 2338A, DIN 6325, and DIN 7. Our dowel pins are available in a choice of materials including mild steel, stainless steel, silver steel, and alloy steel.

Spring Pins

Our range of spring pins include slotted spring pins. These low cost, versatile pins help to simplify assembly and manufacturing processes and are produced by rolling strips to form a slotted cylinder.

These spring pins are precisely manufactured with a diameter slightly larger then the receiving hole. Our range also consists of coiled spring pins produced in a lighter gauge of material and available in three different types:

  • Light duty, ISO 8751 - for use with soft, brittle or thin materials (Series 55)
  • Medium duty, ISO 8750 - our standard stock range (Series A55)
  • Heavy duty, ISO 8748 - used to give extra strength (Series 55)

Clips and Clamps

We provide a variety of clips and clamps including quick release hose clips, saddle clips, and self clamping clips.

We also offer special fixings when the obvious fixing is not the perfect solution. Our range of expertise and broad experience means we can find clips and clamps suited to your application and our tailored productions have included spring clamps for hospital bed adjustments, P clips to MOD drawings, and oversized clamps for marine engines.

We also supply various types of ear clips, tool clips, tri-torque, and worm-drive hose clips.

Clips and Clamps

Mikalor Heavy Duty Clamps

We supply Mikalor, Supra and Superclamps hose clamps preferred by many industry professionals as heavy duty clamps. We stock them in W1, W2,W4 and W5 types of material and in sizes from 17-19mm to 265-275mm.

The Supra CT hose clamp is a W2 clamp fitted with a extended bolt and stainless steel disc spring to allow the clamp to immerse temperature changes and vibrations. They maintain constant and consistent tension.

Ball Bearing Preload Washers

Also known as ball bearing locations discs, our range of ball bearing preload washers are available in toothed or solid styles to suit a diversity of applications.

The advantages of ball bearing preload washers are the tolerance of manufacture, minimised axial space, and small load change with axial deflection and automatic adjustment with a light preload.

Our sizes cover all the traditional bearing designation numbers and full specification information is provided on our downloadable data sheets.

Clevis Pins

These pins are available in inch and metric sizes providing a simple and effective method of connecting drives and linkages where a certain amount of angular rotation is required. Being comparatively simple & sturdy, and requiring no special tooling for insertion, they lend themselves readily to both manual and automatic assemblies.

Our stock range:

  • Mild steel zinc plated (Series A70)
  • Stainless steel (Series D70)
Clevis Pins

Cotter Pins

Originally a ‘belt and braces’ device for industry for the prevention of nuts unscrewing from shafts and for restraining errant Clevis pins, the Cotter pin has developed into numerous designs for newer applications. Due to the development of machinery many varied shapes are capable of volume production.

Our stock range:

  • Mild steel, self colour or zinc plated.
  • A2 & A4 Stainless steel.
  • Brass.
  • Phosphor Bronze.
  • Aircraft and Military specifications, please enquire.

Disc Springs

Disc Springs are a development of the humble Belleville Washer; although physically similar they are made to the more exact standards DIN 2093.

They are capable of being loaded in an axial direction and may be subjected to a constant or cyclic load. They are conically formed and may be used as individual discs or stacked in combinations to obtain desired deflections and loading characteristics. They are extensively used in the friction clutch industry.

Our stocked range:

  • Group 1 (Series F50A or F50D), Punched, cold-formed, edges rounded
  • Group 2 (Series F51A or F51D), Punched, cold-formed, D1, D2 turned, edges rounded
  • Group 3 (Series F52A or F51D), Cold or hot formed, turned on all sides, edges rounded

Available in the following materials:

  • Carbon Steel (A suffix)
  • Stainless steel (D suffix)

Conical Locking Washers

These washers are typically used in heavy bolted applications such as bus bars, transformers and flanges etc. They are also suitable to use with high tensile bolts (8.8). They take up movement in line with the fixing bolt, e.g. temperature changes or settlement over time.

Available in the following materials:

  • Carbon Steel (Series F66A)
  • A2 Stainless steel (Series F66D)
Conical Locking Washers

Serrated Safety Washers

With serrations on the convex and concave surfaces of the disc the component will bite into and hold onto contacting surfaces. Ideal for applications where vibration may be a problem.

Available in two series:

  • Light duty (Series F63A), sometimes referred to as ‘S’ type
  • Medium duty (Series F64A) , sometimes referred to as ‘VS’ type
Serrated Safety Washers

P Clips

P Clips are used extensively in many industries for securing pipes, hoses and cables. The snug fitting EPDM liner enables the clips to clamp the pipes, hoses and cables firmly without any possibility of chafing or damage to the surface of the component being clamped.

The bandwidth is 12.7mm (1/2") with an M6 fixing hole.

  • Material: W1 & W5
  • Available without liner & alternative fixing holes/bandwidths

DIN3016 P Clips also available from stock. 

P Clips

Taper Pins

A well established fixing, requiring a reamed hole which holds very fast. Manufactured as Plain and Extractable Pins.

Taper Pins

Bonded Seals

Our bonded seal is a steel washer with a trapezoidal shaped rubber ring fixed to its inner side. Bonded seal is used where high pressures need more substantial sealing capacity. The metal ring prevents over compression and extrusion of the pliable ring.

The majority of our selection is self centralising bonded seal and provide excellent benefits because they are concentrically located, have captive assembly, and offer efficient installation.

As well as bonded seal, we also supply linch pins, washers, pipe pins, thru locking pins, retaining pins, taper pins, rings, spring pins, and spacers.
