Flat washers distribute load across a fastener bearing surface, reducing the risk of pull-through and surface damage in bolted connections. The zinc plating provides a basic level of corrosion resistance suitable for general indoor and light outdoor applications. These washers conform to SAE dimensional standards, meaning the outer diameter, inner diameter, and thickness fall within the tolerances expected for 5\/16-inch hardware. Plumbers, electricians, HVAC technicians, and general contractors keep SAE flat washers on hand as everyday fastening hardware for equipment mounting, bracket installation, and structural connections.\u003c\/p\u003e\u003cp\u003eThis pack is appropriate for residential and light commercial trade work where 5\/16-inch fasteners are common. Typical applications include equipment base mounting, pipe hanger assemblies, electrical panel bracket work, and general mechanical connections. The 100-count quantity suits service vans and shop stock where bulk availability reduces downtime during installs and service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSAE flat washer profile for standard load distribution on 5\/16-inch fasteners\u003c\/li\u003e\n\u003cli\u003eZinc plated steel construction for corrosion resistance in general-duty applications\u003c\/li\u003e\n\u003cli\u003e100-pack quantity supports job-site and van stock replenishment\u003c\/li\u003e\n\u003cli\u003eConforms to SAE dimensional tolerances for consistent fit across hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard SAE flat washer for use with 5\/16-inch bolts, screws, and threaded rod in general mechanical and trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall flat washers between the fastener head or nut and the mating surface to distribute clamping load.
