Value Collection 565031PS M4x0.7 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 565031PS is a fully threaded button socket cap screw designed for metric fastening applications requiring a low-profile head and 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 carries a material grade of 12.9 and a hardness rating of 38-43 HRC, making it suited for high-stress mechanical assemblies. The hex socket drive accepts a 2.50 mm hex key. Typical installers include machine technicians, industrial maintenance professionals, and field service mechanics working on precision equipment and structural components.

This fastener is appropriate for use in mechanical assemblies, jigs, fixtures, and equipment enclosures where a button-head profile is required to reduce interference with adjacent components. The M4x0.7 thread size and 20 mm length under head make it a common choice for light-duty to medium-duty metric fastening tasks. The black oxide finish provides mild corrosion resistance and reduces light reflection in optical or instrumentation environments.

Key Features

• Alloy steel construction with 12.9 material grade for high tensile strength
• Hardness of 38-43 HRC for wear and deformation resistance
• Black oxide coating for mild corrosion resistance and low-glare finish
• Button head profile reduces snag risk and clearance interference
• Hex socket drive (2.50 mm) for precise torque application
• Meets ANSI/ASME B18.3.4M and ISO 7380 fastener standards

Compatibility

Designed as an OEM-style metric fastener replacement or new installation screw for mechanical assemblies requiring an M4x0.7 thread pitch button socket cap screw with a 4G or 6G thread fit class.

Installation Notes

Installation is performed by mechanical or maintenance technicians using a 2.50 mm hex key or socket driver. De-energize and lock out all equipment before fastener service in accordance with applicable OSHA lockout/tagout procedures. Verify thread fit class compatibility with the mating component before installation. Do not exceed the rated material grade load limits for the fastener size.
