Value Collection 535006PR Button Socket Cap Screw M3x0.5

Product Description

The VALUE COLLECTION 535006PR is a button socket cap screw designed for applications requiring a low-profile fastener with high tensile strength. Manufactured from alloy steel with a black oxide finish, this screw meets ISO 7380 and ANSI/ASME B18.3.4M standards. The M3x0.5 thread and 8 mm length under head make it suited for compact assemblies where standard hex cap screws would interfere with surrounding components. Material grade 12.9 delivers high clamp load capacity. The 2 mm hex socket drive is engaged with a standard hex key or Allen driver. This fastener is typically installed by machinists, maintenance technicians, and mechanical assemblers.

This screw is used in precision mechanical assemblies, machine guarding, electronic enclosures, jigs and fixtures, and general industrial fabrication. The button head profile reduces snag points in moving assemblies and provides a clean finished appearance on visible faces. The black oxide coating offers mild corrosion resistance and reduces light reflection in optical or instrumentation applications. Right-hand thread direction follows standard convention for most assembly work.

Key Features

• Button head with 2 mm hex socket drive for low-profile installation
• Alloy steel construction at material grade 12.9 for high tensile and shear strength
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Fully threaded M3x0.5 metric thread, right-hand direction
• Meets ISO 7380 and ANSI/ASME B18.3.4M fastener standards
• Hardness rated 38-43 HRC for consistent performance under load

Compatibility

Designed as a standard ISO 7380 metric button socket cap screw for use in any M3x0.5 threaded application requiring a low-profile hex socket head fastener.

Installation Notes

Installation requires a 2 mm hex key or Allen driver; use a torque-limiting driver where joint integrity is critical to avoid overdriving the small-diameter thread. Power down any equipment before servicing fasteners on energized assemblies. Thread fit classes 4G and 6G indicate standard tolerance ranges suitable for most general-purpose and precision applications. Follow applicable machine design or assembly specifications for torque requirements specific to the joint material and clamping load needed.
