Rego-Fix presents the Intrlox mini-nut slip-proof clamping system designed to prevent wrenches from slipping off the ER collet nuts. According to the company, unlike standard ER collet nuts, the smaller Intrlox nuts feature an anti-slip design that uses rounded locking grooves situated around the nut profiles as opposed to end face surfaces. Wrenches grip from the sides of the nuts and the action of tightening or loosening temporarily locks wrenches into place.
