Value Collection 535012PR M3x0.5 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535012PR is an M3x0.5 button socket cap screw manufactured from alloy steel with a black oxide coating. It features a low-profile button head and a hex socket drive, designed for applications where a smooth, rounded fastener head is required. The screw is fully threaded with a 16 mm length under the head and conforms to ISO 7380 and ANSI/ASME B18.3.4M standards. At material grade 12.9 and a hardness of 38-43 HRC, it delivers high tensile strength for demanding mechanical assemblies. Installed with a 2 mm hex key, this fastener suits precision equipment, tooling fixtures, and light structural connections in industrial and commercial settings.

This button socket cap screw is used in applications requiring a flush or low-clearance fastening profile, such as machine panels, enclosures, jigs, and fixtures. The metric M3x0.5 thread size and right-hand thread direction make it a standard choice for metric-threaded assemblies across manufacturing, automation, and maintenance operations. Thread fit classes 4G and 6G provide consistent engagement across a range of mating threads. Installation is performed by licensed tradespeople or skilled maintenance technicians using standard metric hex key sets.

Key Features

• ISO 7380 and ANSI/ASME B18.3.4M compliant for standardized metric fastener applications
• Material grade 12.9 alloy steel with 38-43 HRC hardness for high-strength fastening
• Black oxide coating provides mild corrosion resistance and reduces light reflection
• Low-profile button head with 2 mm hex socket drive for use in tight-clearance assemblies
• Fully threaded M3x0.5 right-hand thread with 4G and 6G fit classes for reliable engagement
• 16 mm length under head suits a range of panel and fixture thicknesses

Compatibility

Designed as a standard ISO 7380 metric button socket cap screw for use in any M3x0.5 threaded assembly requiring a grade 12.9 fastener with a hex socket drive.

Installation Notes

Installation requires a 2 mm hex key or driver bit rated for high-torque applications. De-energize and lock out any equipment before fastener replacement or assembly work. Follow applicable ANSI or equipment manufacturer torque guidelines for grade 12.9 M3 fasteners. Do not substitute with a lower-grade fastener in high-stress or dynamic load applications.
