Lee Precision 3/8-24 lock nut for Breech Lock presses

Lee Precision 3/8-24 self-locking nut for Breech Lock presses

Self-locking nut with 3/8-24 thread, original Lee Precision spare part. On Lee presses, this is the nut that secures the linkage pin, or linkbolt, maintaining the coupling between the connecting rod and the ram within the intended clearance.

The integrated locking system prevents loosening caused by the alternating stresses to which the linkage is subjected during every stroke. It is a component that should be replaced whenever the pin is removed: a previously used self-locking nut loses some of its holding capacity and can allow the pin to rotate in its seat, leading to wear.

Main features

• Original Lee Precision spare part
• Self-locking nut, 3/8-24 thread
• Pairs with the 3/8-24 TP2117 linkbolt

Recommended use

Lee lists this nut as a spare part for Breech Lock Challenger, Pro 1000, and Auto Breech Lock Pro / Pro 4000 presses, which share the same linkage pin. Compare the part with your press's exploded view before installation.
