Socket Button Head Screws

Socket button head screws - also known as button socket cap screws - combine the low-profile, domed button head with the hex socket (Allen key) drive that is the hallmark of precision engineering fasteners. At the DIY Hardware Store, our socket button head screws are available in the metric sizes used in engineering, machinery, and fabrication applications where a low-profile, aesthetically clean fastener with high driving torque capability is required.

The button head profile is lower and broader than a standard socket cap head, reducing the overall height of the fastener above the surface. This makes button head screws the preferred choice for applications where clearance above the fastener is limited, where the screw head will be exposed and appearance matters, and in applications where a snagging hazard from a taller head cap screw needs to be avoided. The hex socket drive allows high torque to be applied in confined spaces where a spanner cannot reach.

Available in zinc-plated steel and stainless steel at the DIY Hardware Store in the metric sizes most commonly used in domestic engineering and fabrication applications.
