Product Description

The VALUE COLLECTION 30778 is a standard flat washer manufactured from silicon bronze, designed for use with 1/2 inch screws. Silicon bronze offers strong corrosion resistance, making this washer well suited for marine, plumbing, and outdoor fastening applications where exposure to moisture or harsh environments is a concern. The washer features a 0.531 inch inner diameter, a 1-1/4 inch outer diameter, and a 0.091 inch thickness, conforming to standard dimensional specifications for this screw size class. Sold in a package quantity of 10, this part is appropriate for licensed plumbers, marine mechanics, electricians, and general trade professionals who need reliable, corrosion-resistant hardware.

This washer is used in applications requiring a standard load-distributing flat washer under a bolt head or nut. Silicon bronze construction makes it a preferred choice in coastal construction, marine deck hardware, plumbing rough-in, and electrical bonding installations where galvanic compatibility and corrosion resistance are required. The inch-system dimensions follow standard washer sizing conventions for 1/2 inch fastener assemblies.
