Description
High Tensile Allen Button — Grade 10.9 hex socket (allen) for machinery, tooling, dies and high-strength assembly. Stocked across common sizes and lengths.
The high-tensile Allen button (button head socket cap screw) has a low, rounded head with an internal hex drive, offering a finished appearance and a smooth profile where a tall cap-screw head would get in the way. Its high-tensile construction gives good holding strength while the button head keeps the fastener low-profile and snag-free. It is used in machinery, equipment covers and assemblies where both strength and a clean, low head matter.
High-tensile Allen buttons are supplied in a range of diameters and lengths, driven by a hex key. The low-profile head is the defining feature, chosen for clearance and appearance. Confirm the sizes and grade in the specifications below.
