Value Collection 535022P M4x0.7 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535022P is a fully threaded button socket cap screw designed for metric fastening applications requiring a low-profile head and high tensile strength. Manufactured from alloy steel with a black oxide finish, this screw carries a material grade of 12.9, placing it among the highest strength classes available for metric fasteners. The 2.50 mm hex socket drive accepts a standard hex key for installation in confined spaces where a conventional bolt head would not fit. Licensed tradespeople and maintenance technicians working in mechanical assembly, tooling, and equipment fabrication commonly specify this fastener type.

This button socket cap screw is suited for residential and commercial mechanical assemblies where a low-profile, high-strength metric fastener is required. The M4x0.7 thread size and 8 mm length under head make it appropriate for light structural and machine component attachment. Conformance to ANSI/ASME B18.3.4M and ISO 7380 standards supports use in precision manufacturing, fixture building, and general industrial maintenance contexts.

Key Features

• Grade 12.9 alloy steel construction for high clamp load and tensile strength
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Fully threaded M4x0.7 shank with right-hand thread direction
• 2.50 mm hex socket drive for use with standard metric hex keys
• Hardness rating of 38-43 HRC per material grade specification
• Meets ANSI/ASME B18.3.4M and ISO 7380 fastener standards

Compatibility

Designed as an ISO 7380-compliant metric button socket cap screw for use in any application requiring an M4x0.7 thread with a 4G or 6G thread fit class.

Installation Notes

Installation is typically performed by mechanical technicians or maintenance professionals using a 2.50 mm hex key or matching driver bit. Ensure the mating threaded hole or nut is clean and free of debris before driving the fastener. Do not exceed the torque capacity implied by the Grade 12.9 rating, and consult applicable ASME or ISO specifications for proper torque values specific to your assembly. Black oxide finish offers limited corrosion resistance and is not a substitute for plated or stainless hardware in wet or outdoor environments.
