M4 Penny Washer - 4.3mm ID x 25mm OD | A2 Stainless Steel
Built for automotive and transport repairs, this M4 Penny Washer uses A2 Stainless Steel and a wide 25.0mm outside diameter around a 4.3mm central hole. The larger footprint provides additional support around threaded fixings and helps protect softer or thinner materials from concentrated pressure.
What Are Stainless Steel Penny Washers?
Stainless Steel Penny Washers are flat washers with a larger outside diameter than conventional flat washers. They are also commonly called repair washers or mudguard washers and are used to spread the clamping force from a bolt, screw or nut across a wider area.
Common Applications
- Marine Equipment: A4 variants suit compatible marine and coastal assemblies where increased corrosion resistance is required.
- General Engineering: Pairs with compatible bolts, machine screws and nuts across workshop and production assemblies.
- Construction: Used with bolts and nuts in fabricated frames, brackets, fixings and general building assemblies.
- Furniture Assembly: Helps spread load around threaded fixings used in timber, metal and mixed-material furniture.
