A stainless steel expansion-type bolt for rock climbing routes. To use it you drill the hole, hammer in the stud, and draw it out with a wrench to tighten the collar. The dog-point end prevents the starter threads from being harmed by hammering.
- Made of 304 stainless steel.
- A textured expansion sleeve helps grip rock when being tightened.
- Note: for use with 3/8in. bits. Do not use 10mm bits.
