These dimensions of allen keys can be used to check the accessibility of your bolts were space is limited. For example for an M8 socket head cap screw we need at least 32+8 (head size) = 40mm clearance above the screw for easy accessibility. Refer the following table for metric allen key sizes and dimensions for corresponding socket head cap
