Flat Washers for Clevis Pins are used primarily for a plain washer sized for clevis pins, fitted between the clevis and the split pin or retainer. This page lists the industries and assemblies where they are specified, the selection criteria that matter for each application, installation practice, and the cases where a different fastener type is the correct choice. Parts are supplied to ISO 8738. Stocked across roughly M3 to M100, they cover general to heavy-duty work.
Typical Applications for Flat Washers for Clevis Pins
The most common settings where these are specified:
- Hydraulic cylinders: clevis and rod-end pins.
- Agricultural linkages: pins in tractor implements.
- Lifting equipment: shackle and link pins.
- Construction machinery: pivot pins.
How to Specify Flat Washers for Clevis Pins for Your Application
- Size: Match the nominal size to the mating thread or hole. This product spans M3–M100; check the full table below for the exact dimensions of each size.
- Type & OD: Select flat for load spreading, spring/serrated for anti-loosening, or fender/large-OD for soft or oversized holes.
- Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- Standard: This product is supplied to ISO 8738. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Installation & Assembly Practice
- Place the washer under the rotating element (usually the nut) so tightening does not score the surface.
- Chamfered-hole side of a hardened washer faces the bolt head fillet.
- On serrated-flange hardware, do not add a plain washer — it defeats the serrations.
Common Selection Mistakes with Flat Washers for Clevis Pins
- Relying on a spring washer for locking on class 8.8+ joints — at high preload it flattens and adds nothing.
- Choosing an OD too small for soft material, so the head pulls through or embeds.
Where Flat Washers for Clevis Pins Are Not the Right Choice
A washer does not replace a locking feature on its own in severe vibration, and a spring washer adds little clamp on high-strength joints.

Need a flat washers for clevis pins outside the standard range?
Bore and outside diameter are set by the joint rather than by the bolt, which is why an off-table size is so often the right answer. Made by stamping or punching.
