304 Stainless Steel Square Beveled Washers
What are 304 stainless square beveled washers? 304 stainless steel square beveled washers are corrosion-resistant beveled washers with an angled face for sloped surfaces. The bevel compensates for non-parallel I-beam and channel flanges so the fastener bears level, while the 304 stainless grade resists rust in wet and outdoor structural work.

Why use 304 stainless for beveled washers?
304 is the workhorse austenitic stainless, giving strong corrosion resistance for outdoor and freshwater use at a lower cost than 316. As a beveled washer, its tapered face corrects for the sloped flanges of beams and channels so the nut or bolt head bears squarely and holds preload, while the stainless grade keeps the connection rust-free where a plain iron or galvanized washer would eventually corrode. Pair it with 304 or 18-8 stainless structural hardware. For coastal or saltwater exposure, step up to 316. Note that for high-strength A325 and A490 joints, a hardened F436 washer is specified.
Why choose 304 stainless square beveled washers
- Corrosion resistant: 304 stainless resists rust in wet and outdoor use.
- Levels the bearing: bevel corrects sloped flanges.
- Non-staining: will not rust-streak the structure.
- Match grade: pairs with 304 and 18-8 stainless hardware.
Common applications for 304 stainless beveled washers
- Outdoor I-beam and channel connections
- Corrosion-exposed structural bolting
- Sloped bearing surfaces in wet environments
- Architectural and exposed steelwork

304 Stainless Square Beveled Washers FAQ
Is 304 good for coastal use?
304 handles most outdoor and freshwater exposure but can pit in salt. For coastal or saltwater use, choose 316.
What is a beveled washer used for?
Its angled face compensates for sloped surfaces like I-beam and channel flanges, so the fastener bears on a level surface with consistent preload.
Can stainless beveled washers be used with A325 bolts?
High-strength A325 and A490 joints call for a hardened F436 beveled washer. Stainless beveled washers suit corrosion-exposed structural work at standard strength.
