TLN / TLM Series TANGENTLOK Locknuts

TLN (inch) and TLM (metric) TANGENTLOK locknuts clamp the full circumference of the shaft thread using three tangential socket head screws spaced around the nut body. The three-point clamp is all-metal, symmetrical and repeatable, so the nut holds preload at temperature, stays balanced at speed, and can be released and re-set with a hex key.
