The Pig tool being used to remove carriage bolts from a steel commercial door during fire training. Thank you Instructor Adam Neff, Sr. Staff Corespondent for Hooks & Hooligans Training and member of the Ozark F.O.O.L.S.
Nord-Lock wedge-locking products utilize tension to secure bolted joints in demanding industries exposed to vibration and dynamic loads. The system comprises a pair of washers that creates a wedge-effect and prevents the bolt from rotating loose. Achieve and maintain a high and accurate clamp load with quick and easy installation and removal. A reliable and elegant solution.
