ANCO® PN-LOC®: The Original Structural Locknut

Posted on September 28th, 2016 by vapro

The ANCO® PN-LOC® is our proprietary, all metal, self-locking nut that features a stainless steel ratchet pin. Coupled with a unique controlled lock indention, this non-breakable ratchet pin limits damage to bolt threads, and the removal of galvanizing while ensuring consistent locking torque. This is the nut upon which we built our reputation.
