M2 and M2.5 button heads now available

Button heads have a smaller socket size and shallower depth socket than the equivalent sized cap screw and so more care should be taken not to over-torque, especially on the very small sizes, to avoid rounding of the socket edges. We do not recommend the use of T handle drivers on socket button head screws below M4 size due to the ease of inadvertent over-tightening with this style tool.
It's also crucial to ensure that your hex key of driver is completely inserted before applying significant torque.
If your application is for a high torque connection or the screws will be regularly removed and re-used, we would suggest that a socket cap screw is considered.
