Value Collection 535066P M6x1 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535066P is an M6x1 button socket cap screw manufactured from alloy steel with a black oxide finish. Fully threaded and conforming to ANSI/ASME B18.3.4M and ISO 7380 standards, this fastener delivers a low-profile button head driven by a 4 mm hex socket. At material grade 12.9 with a hardness rating of 38-43 HRC, it provides high tensile strength for demanding mechanical assemblies. The black oxide coating offers mild corrosion resistance and reduces light reflection in finished assemblies. Installed by machinists, millwrights, and maintenance technicians, this screw is a standard choice where a flush-profile cap screw is required.

This fastener suits a wide range of industrial and mechanical applications including machine frames, brackets, guards, fixtures, and equipment panels. The M6x1 metric thread and fully threaded shank make it compatible with standard metric tapped holes at a 4G or 6G thread fit class. Right-hand thread direction follows conventional fastener practice. It is well suited for general manufacturing, maintenance, and OEM assembly environments where metric hardware is specified.

Key Features

• Button head profile provides a low-profile, smooth appearance in finished assemblies
• M6x1 metric thread with fully threaded shank and right-hand thread direction
• 4 mm hex socket drive for use with standard hex keys or hex bit drivers
• Material grade 12.9 alloy steel with 38-43 HRC hardness for high tensile load applications
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Conforms to ANSI/ASME B18.3.4M and ISO 7380 fastener standards

Compatibility

Designed as a standard metric replacement or OEM-style fastener for applications requiring an M6x1 button socket cap screw per ISO 7380 and ANSI/ASME B18.3.4M specifications.

Installation Notes

Installation is performed using a 4 mm hex key or hex socket driver; ensure the correct driver size is used to avoid cam-out and head damage. Verify the receiving tapped hole meets M6x1 thread specifications and the correct thread fit class before installation. Follow applicable industry torque guidelines for grade 12.9 fasteners and the specific joint material. De-energize or lock out any equipment before accessing fastener locations on live machinery per applicable safety standards.
