Button Head Socket Cap Screw (ISO 7380)
Overview
The Button Head Socket Cap Screw, also known as an Allen Button Head Bolt, is a widely used mechanical fastener designed for applications requiring a low-profile rounded head with internal hex drive. Manufactured according to ISO 7380 / DIN 7380 standards, this type of screw offers a combination of clean appearance, strong clamping force, and convenient installation using hex keys or Allen tools.
Compared with traditional hex bolts, button head socket screws provide a smooth rounded head that reduces snagging and improves aesthetic appearance, making them particularly suitable for machinery, electronic equipment, metal structures, and automotive assemblies.
At DCS Fasteners (www.dcscrews.com), these screws are produced using high-quality alloy or carbon steel, ensuring consistent performance and durability in demanding industrial environments.
