Value Collection FWUIB037SM-100BX Flat Washer Brass 100 Pack

Product Description

The VALUE COLLECTION FWUIB037SM-100BX is a standard flat washer designed for use with 3/8 inch screws and fasteners. Manufactured from brass with a plain finish, this washer distributes load across the fastener bearing surface to reduce wear and prevent pull-through on softer materials. The inside diameter measures 0.406 inches, the outside diameter measures 0.875 inches, and the thickness is 0.062 inches. This washer conforms to inch-measurement standards and is sold in a minimum order quantity of 100 pieces per box, making it well-suited for bulk trade and maintenance supply needs.

This flat washer is appropriate for use in plumbing, HVAC, electrical, and general mechanical assemblies where a 3/8 inch fastener is specified and a brass, corrosion-resistant washer is required. Brass construction makes it a common choice in wet or humid environments, as well as applications where galvanic compatibility with brass or copper fittings is a priority. Typical installation scenarios include pipe flanges, equipment mounting, and panel or bracket fastening in residential and light commercial settings.

Installation Notes

Flat washers of this type are installed by plumbers, HVAC technicians, electricians, and general mechanical tradespeople. Always power down or shut off the relevant system before servicing fastened connections. Ensure the washer seats flush against the fastener bearing surface and the mating material. Do not substitute brass washers in applications that require isolation from galvanic corrosion with dissimilar metals without verifying material compatibility.
