Value Collection 3BWLC908 Silicon Bronze Split Lock Washer

Product Description

The Value Collection 3BWLC908 is a silicon bronze split lock washer sized for 1/2 inch screws. Split lock washers create tension under a fastener head or nut, resisting loosening caused by vibration and torque relaxation. This washer is manufactured to ASME B18.21.1 standards, ensuring consistent dimensional tolerances across production runs. With a nominal inside diameter of 0.502 inches and a thickness of 0.125 inches, it delivers reliable clamping performance in corrosion-prone environments where silicon bronze is the preferred alloy over steel. Licensed tradespeople and maintenance professionals use these washers in marine, electrical, and plumbing applications where rust resistance is a priority.

This split lock washer is suited for use in marine hardware assemblies, coastal construction, plumbing fixture installations, and electrical enclosures where moisture and corrosive atmospheres are present. Silicon bronze offers strong resistance to saltwater and many chemical environments, making this washer a practical choice when stainless steel is cost-prohibitive or galvanic compatibility with bronze fittings is required. It fits standard 1/2 inch fastener assemblies and is sold individually with a minimum order quantity of 10 pieces.

Key Features

• Silicon bronze construction provides corrosion resistance in marine and wet environments
• Manufactured to ASME B18.21.1 fastener standard for dimensional consistency
• Split lock design resists loosening under vibration and dynamic loading
• Inside diameter range of 0.506 to 0.518 inches accommodates standard 1/2 inch screw shank tolerances
• Outside diameter range of 0.873 to 0.883 inches for broad compatibility with standard tooling
• Lightweight at 0.01 pounds per piece, suitable for high-count fastener applications

Compatibility

Designed for use with 1/2 inch screw fasteners in assemblies requiring a split lock washer per ASME B18.21.1 specifications.

Installation Notes

Install with the split ends making firm contact against the bearing surface before tightening the fastener to final torque. Power down or de-energize any electrical assembly before installing or replacing hardware within enclosures. Use hand tools appropriate to the fastener drive type; avoid impact drivers on bronze hardware to prevent deformation of the washer or fastener threads. Verify galvanic compatibility between the washer material and mating fastener or substrate before installation in submerged or high-humidity environments.
