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 stainless steel 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. They 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.

*Make sure the sleeve fits loosish inside the hanger hole for this configuration
For hanger hole size & bolt diameter interaction (e.g. the hanger going on the hex bolt vs. the sleeve), we have some observations based off testing HERE of the pros and cons. Our current preferred configuration for the 12mm sleeve bolt is using a 10mm (3/8") hole hanger that goes on the hex bolt. For 10mm sleeve bolts, either configuration is fine, yet an 8mm hanger on the bolt is still our preferred way.
For all general rock climbing and routes with more traffic, we recommend the 12mm sleeve bolt size, especially for any overhanging or steep placements. 10mm sleeve bolts are fine for less steep routes (low angle).
6/5/25 Update: The 12mm 316SS sleeves (batches 0824 and 0425) are on the slightly wider end, so we recommend using better quality drill bits with 4-cutter-tips on the wider end of the ANSI standard. This will better ensure successful installations.
We recommend using 4-cutter drill bits for a more straighter and rounder hole, which the one-piece sleeve benefits from. We also strongly recommend cleaning your holes well before installation. And replace your drill bit or chase the hole with a fresher bit when you begin noticing the sleeve bolt becoming much harder to hammer in . If the embossed text on the hex bolt is becoming to become smashed and unintelligible from having to hammer a lot and hard, you definitely need a fresher bit. A bolt with too tight of a fit breaks off more dust/grit inside the hole, which in turn can get into the threads and increase changes of galling; and worse is if there's too much friction, the top of the sleeve will begin to mushroom outside the hole and you'll have a failed installation. Another tip is to not tighten-up the conical nut where is begins expanding the sleeve before installation; screw it on just enough to hold all the parts together but is a a touch loose.
There's further discussion about these sleeve bolts on this forum thread and this one too.
Some developers have found there to be a learning curve using these style of sleeve bolts, and require a more conscious installation. These have an economical design which keeps them affordable; they don't have the bells-and-whistles other premium sleeve bolts have that can be more haphazardly installed.
