Penny Washers

A penny washer is a wide, flat metal washer with a large outside diameter relative to its bolt-hole diameter. Thanks to the large footprint, penny washers distribute the load of a bolt, screw or nut over a larger surface area – preventing damage to soft or thin materials (wood, plastic, sheet metal), reducing risk of pull-through, and improving joint stability. Theyre used in construction, carpentry, automotive/vehicle repair, marine, DIY, and anywhere a wide bearing surface under a fastener head or nut is required.Depending on material and finish, penny washers can also offer good corrosion resistance (e.g. in stainless-steel versions).FeaturesLarge outer diameter (wide-footprint) – spreads clamping load over a wider area than standard flat washers; especially useful for thin or fragile base materials (wood, plastic, sheet metal).Prevents material damage/pull-through – reduces risk of screw heads or nuts tearing out or sinking into soft substrates.Improves joint stability and load distribution – helps ensure even load distribution, reduces stress concentration under bolt/nut heads.Material & finish options – available in stainless steel (A2 / A4 / 316) for corrosion resistance, zinc-plated steel for general purposes, or mild steel depending on use case. Versatile usage – suitable for general construction, woodworking, furniture assembly, automotive (bodywork, mudguards, panels), marine, DIY, and repair jobs.SpecificationsStainless steel (e.g., A2 / A4 / marine-grade 316) – for high corrosion resistance and outdoor/marine use.Size: 4mm, 5mm, 6mm, 8mm, 12mmSteel, bright zinc-plated (BZP) or zinc-plated – for general use and basic corrosion protectionSpreading load over soft or fragile materials (wood, plastic, sheet metal)Preventing fastener heads or nuts from sinking into or damaging surfacesRepairing or reinforcing existing holes, or covering oversized holesApplications in carpentry, furniture assembly, fencing, automotive bodywork, marine fittings, DIY, and general construction jobs.
