18-8 Grade Stainless Steel 5/16 in. Fender Washers
These stainless steel fender washers are a simple, durable solution for distributing load and preventing pull-through in woodworking, metalwork, plumbing, or automotive repairs. Their corrosion-resistant finish and consistent sizing make them a dependable choice for long-term outdoor or marine use.
- Material: 18-8 stainless steel
- Nominal size: 1/4 in.
- Thickness: 0.062 in.
- Inside Diameter = 11/32 in.
- Outside Diameter = 1-1/2 in.
- Purpose: Oversize fender washer designed to spread clamping force over a larger area to help prevent wood fiber crushing.
A few practical notes:
- The 11/32 in. actual ID is normal for a “5/16 in.” washer so it fits 5/16 in. bolts/screws with clearance.
- 18-8 stainless offers good corrosion resistance for outdoor and marine-adjacent applications.
- The 1-1/2 in. OD makes these much larger than standard flat washers, useful for softwoods, plywood, composites, and oversized holes.
