Value Collection 535076PR M6x1 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535076PR is a fully threaded button socket cap screw designed for metric fastening applications requiring a low-profile head with high clamping strength. Manufactured from alloy steel with a black oxide coating, this screw meets ANSI/ASME B18.3.4M and ISO 7380 standards. It features an M6x1 thread size, a 30mm length under head, and a 4mm hex socket drive. The material grade of 12.9 and a hardness rating of 38-43 HRC make it suitable for high-stress assemblies. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

This button socket cap screw is used in mechanical assemblies, fixtures, and equipment where a standard hex cap screw would protrude beyond acceptable clearance limits. The low-profile button head reduces snag risk in moving-part environments and tight enclosures. Typical applications include machine guarding, structural brackets, tooling plates, and general industrial maintenance. The right-hand thread direction and metric thread fit classes 4G and 6G ensure compatibility with standard metric tapped holes in steel, aluminum, and other common base materials.

Key Features

• Fully threaded M6x1 metric thread, right-hand direction
• 30mm length under head for consistent grip in standard-depth applications
• 4mm hex socket drive for use with common Allen keys and hex bit drivers
• Alloy steel construction at material grade 12.9 for high tensile and proof load capacity
• Black oxide finish provides mild corrosion resistance and reduces light reflection in exposed assemblies
• Hardness of 38-43 HRC meets ISO 7380 and ANSI/ASME B18.3.4M fastener standards

Compatibility

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

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 4mm hex key or hex socket bit driver. Always ensure the mating tapped hole is clean, free of debris, and cut to the correct thread fit class before installation. De-energize and lock out any equipment before fastening components on or near moving parts or electrical assemblies. Do not exceed the rated mechanical limits of the 12.9 grade alloy steel by using impact drivers at uncontrolled torque settings without a calibrated torque tool.
