Value Collection FINWIS0255-100BX Countersunk Washer Steel 100pk

Product Description

The VALUE COLLECTION FINWIS0255-100BX is a standard countersunk washer designed for fastener applications requiring a flush or recessed seating surface. Constructed from steel with a nickel-plated finish, this washer measures 5/32 inch thick with an inside diameter of 0.305 inches and an outside diameter of 25/32 inches. The countersunk profile seats flat-head screws and bolts flush with or below the surface of the workpiece. This washer is installed by electricians, plumbers, HVAC technicians, and general tradespeople wherever a clean, flush fastener finish is required. It ships in a box of 100 pieces.

Countersunk washers like the FINWIS0255-100BX are used across mechanical, electrical, and plumbing applications where panel mounting, sheet metal assembly, or equipment enclosure work demands a low-profile fastener seat. The nickel-plated steel construction provides corrosion resistance suitable for interior installations and light-duty service environments. These washers are well-suited for use with flat-head machine screws and similar countersunk fasteners in light-gauge metal or composite substrates.
