Galvanized 3/4 USS Flat Washers

Overview Galvanized 3/4 USS Flat Washers (09145) are designed for load distribution in threaded fastener assemblies. Manufactured by Midwest Fastener Corp., these washers feature the wide-body USS profile, making them suited for applications where bearing surface area is a priority over tight-tolerance fitment. Attribute Detail MPN 09145 Brand Midwest Fastener / Midwest Fastener Corp. Size 3/4" (USS) Finish Galvanized Pack Quantity 20 pieces Washer Standard USS (United States Standard) Technical Features USS wide-body profile: Larger outside diameter compared to SAE flat washers, distributing clamping load over a greater surface area to reduce pull-through and surface damage on softer substrates. Galvanized finish: Zinc-coated surface provides corrosion resistance, extending service life in outdoor or moisture-exposed installations. Flat, thin plate geometry with center hole: Designed to seat flush beneath a bolt head or nut, evenly transferring fastener load to the mating surface. 3/4" nominal size: Sized to match 3/4" threaded fasteners for straightforward assembly compatibility. Sold in a 20-piece pack: Quantity suitable for single-project or multi-fastener assemblies without over-purchasing. Applications General construction and structural bolting where a wide bearing surface is required Wood framing and timber connections, where the larger USS diameter helps prevent fastener pull-through Outdoor and exposed installations where galvanized corrosion resistance is necessary Repair and maintenance work requiring 3/4" threaded hardware compatibility
