allen button head screw
The Allen button head screw, also known as a socket button head cap screw, is a specialized fastener that combines the reliability of socket head screws with a distinctive low-profile rounded head design. This fastener features a hexagonal socket recessed into its domed head, requiring an Allen wrench or hex key for installation and removal. The button head design offers approximately half the head height of standard socket cap screws while maintaining excellent strength and durability. These screws are typically manufactured from high-grade materials such as alloy steel, stainless steel, or titanium, offering superior corrosion resistance and mechanical properties. The reduced head height makes these screws ideal for applications where space is limited or where a smoother aesthetic appearance is desired. Common applications include automotive components, electronics enclosures, machinery assembly, furniture manufacturing, and precision equipment. The button head design also provides enhanced safety by eliminating sharp edges that could catch on clothing or cause injury, while the recessed socket ensures secure tool engagement during installation and maintenance.
