The 24659 is specifically designed for use with RH-threaded rod ends (Heim joints) and turnbuckles. In a racing suspension, jam nuts are under constant high-frequency vibration and stress. Unlike standard hardware-store nuts, JOES jam nuts are manufactured with precision-cut threads and a low-profile design that provides maximum clamping surface area without taking up unnecessary space on the linkage.
Detailed Technical Specifications
1. High-Tensile Steel Construction
-
Non-Compressible Strength: Made from high-grade steel that resists "pancaking" or deforming when torqued against a rod end or adjuster sleeve.
-
Thin-Profile Design: Engineered as a "Jam Nut" (thinner than a standard hex nut), allowing it to fit in tight clearances where a full-size nut might interfere with the articulation of a rod end.
-
Corrosion Resistance: Typically finished with a protective coating to prevent seizing and rust, ensuring the nut can be loosened easily for mid-race adjustments.
2. Precision RH Threading
-
3/8"-24 Fine Thread: Machined to high tolerances to ensure a smooth, "no-bind" fit on all standard 3/8" RH threaded rod ends.
-
Instant Identification: Because RH threads are less common than standard threads, many JOES jam nuts feature a small notch or "mark" on the hex points for quick identification in a crowded toolbox.
3. Critical Locking Security
-
Vibration Resistance: The 24659 acts as a secondary lock, creating tension against the threads of the rod end to ensure the length of the linkage stays perfectly indexed throughout the race.
-
Essential for Turnbuckles: When used on a tie rod or radius rod, a RH nut is required on one end to allow the center tube to be rotated for adjustments.
