Alloy Steel Metric Button Head Socket Cap Screws

Alloy steel metric button head socket cap screws feature a smooth, low-profile rounded head with an internal hex drive for secure fastening in compact metric mechanical assemblies. The broad bearing surface of the button head provides a finished appearance while maintaining a lower head profile than a standard metric socket head cap screw. The internal hex socket allows installation where external wrench clearance is limited, making these fasteners well suited for machinery, automation equipment, robotics, tooling, fixtures, conveyors, maintenance repairs, and OEM manufacturing.

Manufactured from alloy steel, these metric button head socket cap screws are intended for demanding industrial mechanical applications requiring dependable fastening performance. Their metric thread sizes make them suitable for internationally designed equipment utilizing metric fasteners, while the internal hex drive allows efficient installation with standard metric hex keys or hex bits.

Proper fastener selection should consider metric thread size, screw length, nominal body diameter, head diameter, head height, metric hex socket size, mating-thread engagement, installation clearance, and service conditions. Individual product pages provide verified engineering dimensions to assist engineers and purchasing professionals in selecting the appropriate fastener.

Cold Headers supplies alloy steel metric button head socket cap screws in a broad range of metric thread sizes and lengths, including standard, uncommon, and difficult-to-source configurations. Our catalog is organized to simplify exact-size sourcing while providing consistent engineering information across every product family.
