Button Head Bolt
Socket screws have a wide load-bearing surface that resists loosening. They have a rounded head with a recessed counter bore in the center that accepts an Allen wrench or hex key drive. They are available with a variety of thread options and can be used in applications where tightening or clamping is required, such as in die castings or machine assemblies. A socket button head is often preferred in applications where appearance is important or the clamping material is too thin to countersink a screw.

The rounded head provides a smooth surface and reduces the risk of snagging on objects or tools. This makes them suitable for safety-critical applications, such as in areas where a fastener might snag clothing or equipment in moving machinery.

Compared to standard hex head cap screws, button socket caps have a lower profile for a smaller clearance footprint and offer a more visually appealing appearance. They can also withstand a greater torque without loosening, as they have a larger bearing surface.
