Allen screw 10/40
Allen Screw 10/40 – a steel screw with a socket head is used for mounting the climbing holds. For the Allen screw to fulfill its purpose, it must be used in combination with Round Base T-nut M10/12 with an internal thread.
When assembling climbing holds, DO NOT TIGHTEN the Allen screw with VERY GREAT FORCE! Holds may be damaged. The internal thread of the nut and the external thread of the Allen must screw completely overlap. We list the required number of Allen screws with each climbing hold or climbing set in the e-shop. The sizes of the screws are given when installing the grips on a board with a thickness of 18-20 mm.
