This page lists our range of Metric Stainless Button Head socket screws in M2, M3?,M4, M5 and M6 sizes.

Button Head socket screws have a lower head depth than the equivalent size socket cap screw which combined with the rounded head form give a more aesthetic look.

Socket sizes are stated in millimetres (imperial sizes have been converted to metric).
If you need a key, click on the symbol in the tables below and you will be taken to the allen key and ball driver page.

You can review and edit your order, or submit your order at any time by using the button at the bottom of each list.

We also stock black (HT) button head screws in Metric and UNC threads - please use the buttons above to go to these pages.

 

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 M2 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 connections or the screws will be regularly removed and re-used, we would suggest that a socket cap screw is considered.
