USS flat washers feature a larger outer diameter than SAE-pattern washers, spreading load across a wider bearing surface to reduce fastener pull-through and protect the material beneath. The zinc plating provides a baseline level of corrosion resistance suitable for general indoor and light outdoor use. Each jar contains 100 washers, making this a practical choice for stocking a service vehicle, shop, or job-site parts inventory.\u003c\/p\u003e\u003cp\u003eUSS flat washers in this size see routine use across HVAC, plumbing, electrical, and general mechanical installations wherever a 1\/2 inch bolt or threaded rod requires a broader seating surface. Common applications include equipment mounting, ductwork support hardware, pipe hanger assemblies, panel mounting, and structural connections on light commercial and residential projects. The jar packaging keeps washers contained and organized on a busy job site.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUSS pattern outer diameter for wider load distribution compared to SAE washers\u003c\/li\u003e\n\u003cli\u003eZinc plating for corrosion resistance in general service environments\u003c\/li\u003e\n\u003cli\u003eSized for 1\/2 inch fasteners\u003c\/li\u003e\n\u003cli\u003e100 pieces per jar for efficient bulk stocking\u003c\/li\u003e\n\u003cli\u003eSuitable for HVAC, plumbing, electrical, and mechanical fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/2 inch bolts, hex cap screws, carriage bolts, and threaded rod in USS flat washer applications across residential and light commercial installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eUSS flat washers are installed by general contractors, HVAC technicians, plumbers, and electricians as part of standard bolted connections.
