Description

Experience reliability with our Left-Hand Thread Grade 8 Tap Bolts in full thread. Sized 1-8 x 1-3/4", these fasteners deliver high strength for demanding reverse-thread assemblies, combining Grade 8 alloy steel with a true left-hand thread that resists loosening in rotating systems.

Key specifications

  • Thread orientation: Left-hand
  • Diameter: 1 in
  • Thread pitch: 8 TPI (1-8)
  • Length: 1-3/4 in
  • Thread type: Full thread
  • Material: Grade 8 hardened alloy steel

Applications

  • Heavy machinery and automotive assemblies that require left-hand threading for secure, anti-loosening fastenings.
  • Gear boxes, drive systems, timing assemblies, and other rotating equipment.
  • Reverse-thread configurations where a standard right-hand fastener would loosen under operation.

Why choose Grade 8 left-hand tap bolts

  • Exceptional strength and durability for demanding environments.
  • Left-hand thread design helps prevent loosening in applications with reverse rotation.
  • Full thread length provides reliable engagement and even load distribution along the shank.

For best results, pair these bolts with compatible nuts and washers and follow standard torque guidelines for Grade 8 fasteners to ensure proper clamping force and safety.
