ASMC Industrial - Fender Washers - Heavy Duty Metal Washer for Screws, Automotive, Construction & HVAC Repair, Corrosion Resistant, Flat Stainless Steel 18-8 (A2) - 3/8" x 1 1/4" x 0.05, Pack of 100

These premium 3/8" fender washers are manufactured from high-grade 18-8 (A2) stainless steel containing 18% chromium and 8% nickel, delivering exceptional corrosion protection and rust resistance for outdoor use, automotive projects, marine applications, and demanding installations. The large washers feature an oversized 1 1/4" outer diameter with a precise 3/8" center hole, providing 3x the surface area of standard flat washers to prevent fastener pull-through on thin materials like sheet metal and plastic panels while distributing load evenly and maintaining consistent clamping force. At precisely 0.05" thick, these ultra-thin metal washers and screw washers offer optimal strength while fitting in tight clearance situations, with each washer manufactured to strict dimensional tolerances ensuring consistent quality and performance for complex fastener assemblies. These hardware washers and washers for screws are ideal for fender washers, automotive projects, collision repair, HVAC installations, roofing applications, and construction where thin materials need additional stability and protection, withstanding temperature cycling and moisture exposure while preventing pull-through in thin-gauge metal. The professional bulk packaging includes 100 pieces ideal for busy shops and contractors, with volume pricing up to 1500 pieces, and these washers for bolts and bolt washers fit all standard 3/8" diameter fasteners, including stainless steel bolts, screws, and threaded rods for reliable fastening solutions across automotive, marine, HVAC, and maintenance applications where load distribution is critical.

• PREMIUM STAINLESS STEEL CONSTRUCTION: Made from high-grade 18-8 (A2) stainless steel with 18% chromium and 8% nickel, these large washers and metal washers deliver exceptional corrosion protection for automotive projects, marine applications, and outdoor installations. The premium stainless steel composition provides superior defense against rust, oxidation, and chemical degradation, where standard fasteners would quickly fail in demanding environments.
• LARGE FLAT WASHERS FOR BOLTS: Engineered with oversized 1 1/4" outer diameter and precise 3/8" center hole, these hardware washers and washers for screws provide 3x the surface area of standard flat washers. This expanded contact area prevents fastener pull-through on thin materials like sheet metal and plastic panels, while distributing load evenly to maintain consistent clamping force and minimize material deformation under heavy loads.
• ULTRA-THIN PRECISION DESIGN: At precisely 0.05" thick, these metal washers flat and screw washers, offer optimal strength while fitting in tight clearance situations and confined spaces. Each washer is manufactured to strict dimensional tolerances with controlled processes ensuring consistent quality and performance. The minimal thickness enables stacking when an additional bearing surface is needed for complex fastener assemblies.
• VERSATILE AUTOMOTIVE APPLICATIONS: Ideal for fender washers, automotive projects, collision repair, HVAC installations, roofing applications, and construction where thin materials need additional stability and protection. These 3/8 stainless washers and stainless washers withstand temperature cycling and moisture exposure while preventing pull-through in thin-gauge metal for professional contractors, mechanics, and repair specialists.
• PROFESSIONAL BULK PACKAGING: Comes in convenient 100-piece quantities suitable for busy shops and contractors, with economical volume pricing available up to 1500 pieces for large projects. These washers for bolts and bolt washers fit all standard 3/8" diameter fasteners, including stainless steel bolts, screws, and threaded rods, providing reliable fastening solutions across automotive, marine, HVAC, and maintenance applications.
