Value Collection 31393 Countersunk Washer Nickel Brass 100pk

Product Description

The VALUE COLLECTION 31393 is a standard countersunk washer manufactured from brass with a nickel-plated finish. Designed to seat flush against countersunk fastener heads, this washer distributes clamping load evenly while providing a clean, finished appearance at the fastener surface. The 0.488-inch outside diameter and 3/32-inch thickness make it suitable for light-duty mechanical, electrical, and plumbing applications where a low-profile seating washer is required. Sold in packs of 100, this part is well suited for contractors and technicians who install fasteners in volume.

This countersunk washer is used in applications where a standard flat washer would sit proud of the mating surface and an angled bearing surface is needed to match a countersunk hole profile. Typical applications include panel mounting, enclosure assembly, ductwork, and general mechanical fastening in both residential and light commercial settings. The nickel-plated brass construction offers corrosion resistance in mildly humid environments.

Installation Notes

Installed by electricians, HVAC technicians, plumbers, and general contractors during panel, enclosure, or component fastening. Confirm that the countersink angle of the washer matches the mating surface before tightening. Do not overtighten fasteners, as brass can deform under excessive load. Follow applicable mechanical codes for the specific assembly or equipment being serviced.
