Structural washers are the hardened washers used under the bolt head and nut in structural bolting assemblies. AIMS Industrial lists 6 structural washer products from Hobson, Bremick and Applied Bolting: K0 and K2 structural washers, metric structural flat washers, and a load indicator washer, in plain, black and galvanised finishes from M12 to M36. For more on washer types, see our Types of Washers guide.

Choosing a structural washer
Match the washer to the bolt size and to the bolt and nut it is paired with. Use the same finish across the assembly where you can: galvanised washers with galvanised bolts and nuts, and plain or black washers with plain or black fasteners. Mixing finishes outdoors is worth avoiding, because it can lead to corrosion.
The project specification and the structural engineer decide which washer type and class an assembly needs, so confirm those before you order. For direct tension indicator washers, see our Durasquirt washers range.
Always check the data sheet. Confirm the size, finish and any certification your project requires before you order.

What structural washers does AIMS list?
We list 6 structural washer products: Hobson K0 and K2 structural washers, high tensile metric structural flat washers from Hobson and Bremick, and an Applied Bolting load indicator washer.
What sizes are available?
Sizes run from M12 to M36 across the range. The load indicator washer is listed in M16, M20 and M24. Check each listing for the exact sizes.
What finishes are available?
Plain, black, hot dip galvanised and mechanical galvanised. Each listing shows its finish in the title.
Can I use a standard flat washer instead of a structural washer?
Check the project specification first. Structural assemblies call for the washer type the specification names, so confirm with the engineer before you substitute.
Do you have direct tension indicator washers?
Yes, see our Durasquirt washers collection for DTI washers.
