Description

Upgrade your fastening with the Flange Bolts Serrated Hex Washer Case Hardened Zinc 5/16-18 x 3/4. Designed for reliable performance in automotive, machinery, and industrial applications, this bolt combines a built-in flange, a serrated under-head, and a durable zinc finish for lasting corrosion resistance.

  • Material and finish: Case-hardened steel with zinc plating provides enhanced wear resistance and corrosion protection.
  • Size and thread: 5/16-18 coarse thread for secure engagement with standard threaded holes and nuts.
  • Flange and serrations: Integrated flange distributes load for a flush seat, while serrations help resist loosening on vibration-prone surfaces.
  • Head style: Hex washer head accepts standard drivers and sockets for easy installation in tight spaces.
  • Length: 3/4 inch grip length suits common automotive and equipment applications.
  • Recommended uses: Ideal for fastenings in equipment, machinery, automotive assemblies, and general purpose projects.

Choose these bolts for a secure, durable fastener that holds up under vibration and exposure. The zinc finish provides corrosion resistance, while the case-hardened core ensures long-lasting strength in demanding environments.
