Most of our BOLT-ON HOLDS have 2 holes:

• The 10mm diameter hole is for fixing the hold into a standard 3/8" t-nut and requires 3/8" bolts of varying lengths.
• The 3/16" diameter hole prevents the holds from spinning. We recommend using non-self drilling timber screws with head size of 8G/10G x 30mm to 60mm.

All 10mm holes and most 3/16" holes have been reinforced with marine grade stainless steel washers (316).

TNUT Climbing does not include bolts and/or screws with any sets of holds.
