Description

3/8-24 Left-Hand Thread Jam Nut – Ideal for Tie Rods & Steering Linkages


This 3/8-24 left-hand thread jam nut is designed to lock securely against another nut or threaded fastener, preventing loosening under vibration or movement. Commonly used in automotive, off-road, and karting applications, it’s especially well-suited for tie rod ends and steering linkage heim joints where a secure, adjustable connection is critical.


Key Features:

  • Thread Size: 3/8-24 (UNF – Unified National Fine Thread)
  • Thread Direction: Left-hand (reverse thread)
  • Function: Designed to “jam” or lock against another nut to prevent loosening
  • Common Uses: Tie rod ends, steering linkage heims, suspension components, and other dynamic assemblies


Why Use a Jam Nut?

Jam nuts are thinner than standard nuts and are typically used in pairs. When tightened against a standard nut, they create a locking action that resists loosening from vibrations, impacts, or dynamic motion—ideal for adjustable assemblies like steering systems or suspension arms.
