Value Collection LWIBR0-3USA-100BX No. 3 Split Lock Washer

Product Description

The VALUE COLLECTION LWIBR0-3USA-100BX is a No. 3 split lock washer manufactured from silicon bronze with a bright, uncoated finish. Split lock washers are used under fastener heads or nuts to resist loosening caused by vibration and torque relaxation. This washer measures 0.101 inches minimum inside diameter, up to 0.107 inches maximum inside diameter, with a maximum outside diameter of 0.195 inches and a thickness of 0.025 inches. Silicon bronze construction provides corrosion resistance in wet and marine environments. This box contains a minimum order quantity of 100 washers per package. Electricians, plumbers, marine contractors, and mechanical assemblers commonly specify silicon bronze hardware where galvanic compatibility or moisture exposure is a concern.

This split lock washer is suited for use with No. 3 machine screws in residential, commercial, and marine fastening applications. Typical install scenarios include panel assembly, fixture mounting, and any bolted joint where vibration or thermal cycling could loosen a standard flat washer. Silicon bronze is a preferred material when working near copper piping, bronze fittings, or in salt-air environments where steel hardware would corrode prematurely.

Key Features

• Silicon bronze construction resists corrosion in wet, marine, and chemically active environments
• Split lock design bites into mating surfaces to resist rotational loosening under vibration
• Bright uncoated finish — no plating to flake, chip, or contaminate sensitive assemblies
• Sized for No. 3 screws with 0.101 to 0.107 inch ID range
• Sold in 100-piece minimum order quantity for job-lot stocking

Compatibility

Designed for use with No. 3 machine screws in inch-measurement fastening applications requiring a split lock washer.

Installation Notes

Install split lock washers between the fastener bearing surface and the mating part before driving the screw or nut to final torque. Ensure the mating surfaces are clean and free of debris so the washer edges can seat properly. Silicon bronze hardware should be handled with clean hands or gloves when used in corrosion-sensitive assemblies to avoid contamination. No special tools are required beyond standard hand or power screwdrivers appropriate for the No. 3 screw drive type.
