QA1 Precision Products JNL5S Left Hand Jam Nut Steel Hex Suspension Rod End Bearing - 5/16-24 1/2

The QA1 Precision Products JNL5S is a precision-engineered steel jam nut designed for securing rod ends, heim joints, and suspension components. This jam nut features left-hand 5/16-24 threads, making it ideal for applications where reverse threading is required to prevent self-loosening under vibration or rotation.

Key Specifications:

• Thread Size: 5/16-24 Left Hand (LH)
• Material: High-strength steel construction
• Hex Size: 1/2 inch across flats for standard wrench fitment
• Width: 3/16 inch jam nut profile
• Finish: Steel (natural or zinc-plated)

This jam nut is commonly used in racing suspension systems, custom steering linkages, and other precision automotive applications where QA1 rod ends and spherical bearings are employed. The left-hand thread configuration prevents accidental loosening when paired with right-hand threaded components in counter-rotating assemblies. The thin 3/16-inch profile allows for use in tight clearance situations while the 1/2-inch hex provides adequate grip for proper torque application.
