Value Collection CFLW044OP-025BX Flat Washer Copper 25pk

Product Description

The VALUE COLLECTION CFLW044OP-025BX is a standard flat washer sized for 7/16 inch screws, manufactured from copper with a plain finish. It features a 0.5 inch inside diameter, a 1.125 inch outside diameter, and a thickness of 0.078 inches. Flat washers of this type are used to distribute load across a fastener bearing surface, preventing pull-through and protecting softer base materials. Copper construction provides natural corrosion resistance and electrical conductivity, making this washer well suited for plumbing, electrical, and marine service applications where steel hardware is prone to galvanic or chemical corrosion. Licensed tradespeople and experienced DIYers install these as part of standard fastener assemblies.

This washer is suited for residential and commercial applications where a 7/16 inch fastener is used against copper, brass, or other soft metal substrates. Common install scenarios include pipe flange connections, electrical grounding assemblies, HVAC equipment mounting, and general mechanical fastening where copper compatibility is required. Sold in a minimum order quantity of 25 pieces per package, making it practical for service vehicle stock or small job lots.

Compatibility

Designed as a standard flat washer for use with 7/16 inch screws and bolts in inch-measurement fastener systems. Suitable for copper-compatible assemblies in plumbing, electrical, and HVAC applications.

Installation Notes

Install using standard hand tools appropriate for the fastener being used. Ensure the mating fastener and substrate materials are compatible with copper to avoid unintended galvanic reaction with dissimilar metals. Follow applicable codes such as the NEC for electrical assemblies or the IPC for plumbing applications when these washers are used in regulated systems. Inspect washers for deformation before installation and do not reuse washers that show signs of cracking or excessive compression.
