Detail & Specs

Bi-Directional All Metal Locking Hex Nut

3 squeeze points where the inner threading is distorted to pinch the bolt when screwed on to a nut. This secures the fastener assembly in place and prevents loosening caused by continuous vibration.

Unlike a conical metal lock nut where the domed / chamfered edge must always be installed from one side, BILOC nuts can be installed from either direction. Biloc nuts are considered a non-standard part, but are based on the dimensional specifications for DIN 980 / ISO 7042.

Hardened Class 10 metric lock nuts provide a high strength, high tensile fastening solution. Commonly paired with Class 10.9 metric bolts and screws. The all metal construction is better for higher temperature installations where a nylon-insert lock nut might fail. Zinc Plated finish provides corrosion resistance without sacrificing strength.

Also known as Stover nut, all metal lock nut, all metal prevailing torque nut, all metal hexagon high nut, automation style self locking nut.
