Description

Flange Bolts Serrated Hex Washer Stainless 5/16-18 X 2 are engineered for dependable, corrosion-resistant fastening in a wide range of indoor and outdoor applications. The 5/16-18 UNC thread and 2-inch length provide versatile mating options in automotive, hardware, and construction projects.

Made from stainless steel, these bolts deliver excellent corrosion resistance and strength, making them suitable for moisture-prone environments. The serrated flange design distributes clamping force to reduce pull-through, while the hex washer head simplifies installation with a standard wrench or socket.

Key features

  • Material: Stainless steel
  • Thread: 5/16-18 UNC
  • Length: 2 inches
  • Head style: Serrated flange hex washer
  • Corrosion resistance for indoor and outdoor use

Applications

Ideal for securing panels, brackets, and structural components where a flush, load-distributing fastener is required. Use with a compatible nut or tapped hole in automotive, machinery, construction, and outdoor installations.

Installation tips

  • Align parts and start the thread by hand to prevent cross-threading.
  • Use the appropriate wrench or socket for firm, even tightening.
  • Follow your project’s torque specifications to avoid over-tightening.

Note: Specifications are typical; refer to your hardware supplier for exact material and tolerance details.
