By distributing screw pressure on a wide area, our E-insert system allows either CHC screws (cylinder head cap screws) or FHC screws (Flat head cap screw).
It's better to use a torque wrench. Best settings are:
- 10Nm for sizes S to XS
- 20Nm for sizes M to L
- 30Nm for sizes XL to XXL
Impact wrench is not advised. The main 12mm diameter hole is designed for fixing climbing hold to the wall. Screw lenghts are given for 10mm diameter CHC screws. Please allow 5 more millimeters for FHC screws. To avoid hold spinning, please add VBA screw (up to 5 mm diameter) into the additional hole.
Screws are not included.
