The Industry Standard for Structural Locknuts
The ANCO® PN LOC® is our proprietary, all-metal, self-locking nut featuring a stainless steel ratchet pin. Coupled with a unique controlled lock indentation, this non-breakable ratchet pin limits both damage to bolt threads and the removal of galvanizing, while ensuring consistent locking torque.
