Jam nut 1.25 in - 12tpi

The Artec Industries Jam Nut is a locking nut for 1.25"-12 TPI fine-thread rod ends. Threaded onto the rod end and tightened against a threaded tube insert, it keeps the joint from backing out under the constant load reversal of a suspension link. It is the hardware that keeps an adjustable link at its set length on the trail.

Key Features

• Sized for 1.25 inch, 12 threads-per-inch (fine thread) rod ends.
• Locks a rod end against a threaded tube insert to prevent loosening.
• Available in left-hand (reverse) and right-hand (standard) thread.
• Keeps adjustable links from changing length once set.

Fitment & Compatibility

Universal suspension hardware for anyone building or adjusting links with 1.25"-12 TPI rod ends. Match the thread direction to your setup: order a right-hand (standard) nut for a right-hand rod end and a left-hand (reverse) nut for the opposite end so a link can be adjusted without unthreading either joint. It pairs with the 1.25"-12 TPI Tube Adapter that threads into the link tube.

Frequently Asked Questions

What thread does this jam nut fit?
It fits 1.25 inch, 12 threads-per-inch fine-thread rod ends.

How do I choose left-hand versus right-hand?
Match the nut to the rod end's thread direction. A common adjustable link uses one right-hand and one left-hand end so you can change length by turning the tube; order the nut hand to match each end.

What does the jam nut actually do?
Tightened against a threaded tube insert, it locks the rod end at its set position so vibration and load reversal cannot back it out.

What tube insert works with it?
Artec's 1.25"-12 TPI Tube Adapter threads into the link tube and accepts the 1.25" rod end and this jam nut.

Do you offer other sizes?
Yes. Artec also makes the 7/8"-14 TPI jam nut and 3/4"-16 TPI jam nut for smaller rod ends.
