These Left Hand Thread Grade 8 Tap Bolts are engineered for high-strength fastening with reverse-torque resistance. The full-thread design ensures continuous engagement along the entire shank for maximum grip. Ideal for applications requiring a 1/4-20 bolt size and 1-3/4 inch length.

  • Left Hand Thread: Tightens under reverse torque, helping prevent loosening in rotating or dynamic assemblies.
  • Grade 8: High-strength fastener suitable for demanding service.
  • Full Thread: Engages the threaded holes along the entire length for secure clamping.
  • Size & Length: 1/4-20 thread, 1-3/4 inches long.

Recommended uses include machinery, tooling, and industrial equipment where reliable, durable fasteners are essential. Pair with the appropriate nuts or tapped holes designed for 1/4-20 threads and follow standard torque guidelines for Grade 8 hardware.
