5/8-18 RH Steel Jam Nuts Thin OD 4pk

The ALLSTAR PERFORMANCE 5/8-18 RH Steel Jam Nuts Thin OD 4-pack (ALL 18292) is a precision fastener set designed for applications where controlled thread locking and vibration resistance are critical. These right-hand thread jam nuts are ideal for tight mounting spaces, ensuring that standard nut dimensions do not create interference or clearance issues.

Machined from steel with a zinc oxide finish, these jam nuts provide reliable corrosion resistance and secure fastening in both automotive and mechanical assembly work. The 5/8-18 specification refers to a 5/8-inch diameter with 18 threads per inch, commonly used in various mechanical applications. The thin OD design allows two nuts to be torqued against each other on a single bolt, creating a positive lock without requiring a thread-locking compound.

This four-pack is perfect for shops, fabricators, and enthusiasts who require precision hardware for steering boxes, rod ends, and shaft connections where loosening due to vibration poses a safety risk. The compact package (0.08 lbs) makes it practical for emergency repair kits, replacement sets, or stock replenishment. Steel construction ensures dimensional stability and consistent torque values across repeated fastening cycles.
