Description & Tech Specs

Why sleeve bolts? Sleeve bolts make for easy installation and secure hold on softer rock. The sleeve adds strength by making contact with the rock throughout the length of embedment. This makes sleeve bolts more appropriate for weaker rock and varying rock types. 

This 4-piece 316 Stainless Steel Sleeve Bolt is composed of a hex cap bolt, washer, sleeve, and a straight-knurled conical nut of all the same grade. All four components have been passivated for extra corrosion resistance. Climbing Taiwan chose hex bolts (partially threaded) because they offer additional strength over set screws (fully threaded) particularly in radial loads. Components are manufactured in China and further processed, inspected, and assembled in Taiwan. 

Since sleeve bolts have a smaller bolt enclosed in a larger sleeve, installation is different compared to wedge bolts. Tthey will require a differently sized hanger compared to the drill bit that’s needed to drill out the hole. Below is a guide to each bit, hanger, and wrench required for each.
