Description

Flange Bolts Serrated Hex Washer Case Hardened Zinc 3/8-16 X 1 3/4 are high-performance fasteners designed for secure, vibration-resistant assemblies in automotive, machinery, and equipment applications. Featuring a serrated hex washer, these bolts provide increased clamp load and anti-rotation properties, while the flange keeps the bolt seated without a separate washer.

Crafted from hardened steel and finished with a zinc-coated, case-hardened treatment, they deliver enhanced strength, wear resistance, and corrosion protection in demanding environments.

Why choose these flange bolts

  • Thread Size: 3/8-16
  • Length: 1 3/4 in
  • Head Type: Flange with serrated hex washer for a flat seating surface and built-in locking action
  • Material & Finish: Hardened steel with zinc finish; case-hardened for superior durability
  • Drive: Hex
  • Applications: Ideal for automotive, machinery, equipment, and structural assemblies where a secure, long-lasting fastener is required

Tip: For best results, pair these bolts with compatible nuts and washers and follow recommended torque specs to achieve optimal clamping force and prevent thread stripping.
