Description
Overview:
Zinc-plated steel rivet washers used to spread the load of a rivet and protect the work surface. Sized for 1/8 in (3.2 mm) rivets with a 1/2 in (12.7 mm) outside diameter, they provide a wider bearing area to reduce pull-through and surface marking on thin sheet and softer materials. The bright zinc plating offers practical corrosion resistance for workshop and site use. Supplied in a bulk pack of 1000 (MPN 903 1625), these flat washers are suited to general fabrication, maintenance and repair on machinery guards, ducting, vehicle bodywork, trailers, gates and enclosures. Use with hand, cordless, or pneumatic riveters when setting 3.2 mm blind/pop rivets in aluminium, steel, stainless, plastics or composites.
Key Features:
- Inner diameter sized for 1/8 in (3.2 mm) rivets; outer diameter 1/2 in (12.7 mm) for a generous bearing surface
- Zinc-plated steel for dependable rust resistance in everyday UK site and workshop conditions
- Distributes clamping force to help prevent pull-through on thin sheet, plastics and other softer substrates
- Helps protect painted, coated or anodised surfaces during riveting
- Consistent dimensions for reliable, repeatable setting with standard 3.2 mm blind rivets
- Smooth, flat profile for neat seating under the rivet head or on the blind side
- Works with manual hand riveters, cordless rivet tools and pneumatic rivet guns
- Bulk pack of 1000 pieces (MPN 903 1625) for convenient stocking and reduced downtime
- Versatile fit for general metal fabrication, assembly and repair across construction, automotive and agricultural tasks
Typical Applications:
Reinforcing rivet joints in thin sheet metal, plastics and composites; HVAC ducting and brackets; vehicle panels and body repairs; plant and agricultural machinery guards; signage and enclosures; roofing and cladding trims; trailers and general metalwork. Use wherever a 3.2 mm rivet needs extra bearing area or where surface protection is required on the set or blind side.
