The VALUE COLLECTION 3BWLC906 is a silicon bronze split lock washer sized for 3/8 inch screws. It features a nominal inside diameter of 0.377 inches, an outside diameter ranging from 0.683 to 0.691 inches, and a thickness of 0.094 inches. Silicon bronze construction provides strong corrosion resistance in marine, coastal, and high-moisture environments where steel hardware would degrade quickly. The split lock design bites into the mating surface and fastener bearing face to resist loosening under vibration. This washer is manufactured to ASME B18.21.1 standards and is sold individually with a minimum order quantity of 100 pieces.
This split lock washer is suited for fastening applications in plumbing, marine, electrical, and general mechanical assemblies where corrosion resistance is a priority. Silicon bronze is commonly specified in installations near saltwater, in wet plumbing chases, or on exterior structural connections. It is appropriate for residential and light commercial work wherever a 3/8 inch fastener requires a lock washer that will hold up in corrosive or humid conditions.
Designed for use with 3/8 inch screws and bolts in assemblies requiring a split lock washer per ASME B18.21.1. Verify bearing surface clearance against the 0.683 to 0.691 inch outside diameter before installation.
Install between the fastener bearing face and the mating surface with the split ends oriented to bite into both surfaces upon tightening. Ensure the mating surface is clean and free of debris before seating the washer. Follow applicable mechanical or plumbing codes for fastener torque requirements specific to the joint material and application. Do not substitute silicon bronze hardware in applications requiring specific alloy ratings without verifying material compatibility.
