[100 PKG] Structural Flat Washers Steel Zinc F436 Type 1 7/16

Structural Flat Washers in steel with a durable zinc finish provide reliable bearing surfaces for heavy-duty bolted joints. These washers are manufactured to ASTM F436 Type 1 standards and sized at 7/16 inch, making them a trusted choice for structural connections and demanding applications.

Constructed from steel and zinc-plated for corrosion resistance, they distribute load evenly, protect mating surfaces, and help prevent pull-through in critical assemblies.

• Material: Steel with zinc plating for lasting durability and corrosion resistance.
• Standards: ASTM F436 Type 1 compliant, ensuring consistent thickness and geometry.
• Size: 7/16 inch nominal size for common fasteners used in construction and machinery.
• Finish: Zinc-coated to resist rust and extend service life.
• Applications: Ideal for structural, construction, machinery, automotive, and timber-framing bolt assemblies.

Why choose these washers? They provide even load distribution under fasteners, protect bearing surfaces, and improve joint stability in high-stress environments.

Tips for best performance: Select the correct 7/16 inch washer to fit your bolt and hole, ensure the surface is clean and flat before tightening, and follow the recommended torque to maximize clamping force and longevity.
