The HOLO-KROME 86011 is an M4x0.70 button socket cap screw designed for metric fastening applications requiring a low-profile head with high tensile strength. Manufactured from Grade 12.9 alloy steel with a black oxide finish, this screw delivers hardness of 38 HRC and resists corrosion in typical industrial environments. The hex socket drive accepts a 2.55 mm hex key for installation and removal. It is fully threaded along its 12 mm length under the head, making it well-suited for through-hole and shallow blind-hole installations. Licensed fastener technicians, millwrights, and mechanical contractors install this type of hardware in precision assemblies where a standard hex cap screw profile is too tall.
This button socket cap screw is used in light-to-medium duty metric assemblies across industrial, OEM, and maintenance applications. The low-profile button head distributes clamping load over a wider bearing surface than a standard socket head, making it a common choice for sheet metal panels, enclosures, guards, and fixtures. It conforms to ANSI/ASME B18.3 and ASTM F835 standards. The right-hand thread and 4G/6G thread fit class ensure consistent engagement with standard metric tapped holes. Sold individually; minimum order quantity is 100 pieces.
Designed for use in standard metric tapped holes with M4x0.70 right-hand thread pitch, conforming to 4G and 6G thread fit classes per ANSI/ASME B18.3.
Installation and removal require a 2.55 mm hex key or bit driver; use of an improperly sized driver can damage the socket recess. De-energize or lock out equipment before servicing any assembly that incorporates this fastener. Apply thread-locking compound or appropriate preload per the equipment manufacturer's torque specification for the joint material. Discard fasteners that show signs of deformation, galling, or corrosion before reinstalling.
