Value Collection -93771-1 Flat Washer 1 in 18-8 Ss

Product Description

The VALUE COLLECTION -93771-1 is a standard flat washer sized for 1-inch screws, manufactured from 18-8 stainless steel for corrosion resistance in wet, outdoor, and marine-adjacent environments. The washer measures 1-1/16 inches inside diameter, 2 inches outside diameter, and 0.134 inches thick, conforming to ASME B18.22.1 1965. It distributes clamping load evenly across a fastened joint, reducing surface damage and preventing fastener pull-through. Plumbers, HVAC technicians, electricians, and general trade contractors use these washers wherever a corrosion-resistant fastening solution is required.

This washer is suited for residential and light commercial construction, mechanical rooms, rooftop equipment mounting, and any application where a 1-inch screw requires a standard load-distributing washer. The 18-8 stainless steel grade offers good resistance to oxidation and mild chemicals, making it appropriate for plumbing, HVAC bracket work, electrical enclosure mounting, and outdoor structural connections.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Conforms to ASME B18.22.1 1965 fastener standard for dimensional consistency
• 1-1/16 inch inside diameter fits 1-inch screw shanks with proper clearance
• 2-inch outside diameter distributes clamping load over a broad surface area
• 0.134-inch thickness provides solid bearing surface without excessive stack height

Compatibility

Designed for use with 1-inch screw fasteners in standard flat washer applications conforming to ASME B18.22.1 inch-series dimensions.

Installation Notes

Install using standard hand tools; no special tooling is required for flat washer placement. Ensure the fastener and mating hardware are compatible in material to avoid galvanic corrosion in mixed-metal assemblies. Follow applicable mechanical and structural codes for fastener torque and joint requirements. Always verify screw shank diameter against washer inside diameter before installation.
