The CM Mid-Grip is designed for applications in the scaffolding industry. The redesigned Mid-Grip features a hexagon bolt head that fits securely into a forged, hex-shaped socket that prevents spinning even after repeated use and re-torqueing. It has precise threading on the nut and bolt to ensure tight alignment. This design also allows for full arc wrench swing, making installation and retightening quick and easy. Available in sizes 3/16" - 5/8" (old-style 3/4" also available by request).
