Value Collection 535056PR M5x0.8 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535056PR is a fully threaded button socket cap screw manufactured from alloy steel with a black oxide finish. The button head profile provides a low-profile clamping surface, and the 3 mm hex socket drive allows installation with a standard hex key or Allen driver. Built to material grade 12.9, this fastener delivers high tensile strength suitable for demanding mechanical and structural assemblies. Hardness is rated at 38-43 HRC. Thread size is M5x0.8 metric with a right-hand thread direction, and the length under head is 20 mm. Meets ANSI/ASME B18.3.4M and ISO 7380 standards. Installed by machinists, maintenance technicians, and assembly professionals across industrial and OEM applications.

This screw is suited for metric fastening applications where a low-profile head is required to clear adjacent components or mating surfaces. Typical use cases include machine frames, enclosures, fixtures, and equipment panels where alloy steel strength and corrosion-resistant black oxide coating are specified. The thread fit class is 4G/6G, consistent with standard metric tolerance requirements for general industrial assembly.

Key Features

• Material grade 12.9 alloy steel for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Button head with 3 mm hex socket drive for low-profile installations
• Fully threaded M5x0.8 right-hand metric thread
• Meets ANSI/ASME B18.3.4M and ISO 7380 fastener standards
• Hardness rated 38-43 HRC for consistent mechanical performance

Compatibility

Designed as an OEM-style metric fastener for general industrial, mechanical, and structural assemblies requiring an M5x0.8 button socket cap screw to ANSI/ASME B18.3.4M and ISO 7380 specifications.

Installation Notes

Install using a 3 mm hex key or Allen driver rated for the torque demands of a grade 12.9 fastener. De-energize and lock out all equipment before fastener replacement in powered assemblies. Do not substitute a lower-grade fastener in applications specified for grade 12.9. Follow applicable ANSI or equipment manufacturer torque guidelines for the fastener diameter and application.
