Fixe SS 12mm x 55mm Sleeve Bolt The Fixe Sleeve Bolt was designed specifically for rock climbing. The Sleeve Bolt uses the same expansion principal as the Rawl 5-Piece bolt. The sleeve expands by tightening the nut which draws the tapered stud from the hole. This system places the threads outside of the rock eliminating hidden thread and nose cone corrosion. This bolt can be used in soft and pocketed rock. CE/UIAA Certified 12x70mm Weight: 80g 304 Stainless Steel 12mm Bolts TORQUE TO: 25 Foot Pounds / 35Nm Requires 12mm bit/hole
