Value Collection 534014PR M3x0.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534014PR is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. The 90-degree flat head sits flush with or below the mating surface when properly installed, making it well-suited for assemblies where clearance is critical. Machined from grade 12.9 alloy steel and finished with black oxide, this fastener delivers high tensile strength with basic corrosion resistance. The hex socket drive accepts a 2 mm hex key. Thread size is M3x0.5 with a 20 mm overall length and full threading along the shank. Conforms to DIN 7991 standard.

This fastener is used across precision mechanical assemblies, tooling fixtures, machine guards, and equipment enclosures where a low-profile head is required. The metric M3x0.5 thread pitch is common in light machinery, electronics enclosures, robotics, and instrumentation panels. Grade 12.9 material grade makes this screw appropriate for high-stress joint applications. Installers in manufacturing, maintenance, and mechanical trades will find this fastener compatible with standard metric countersunk hole patterns.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• 90-degree flat head profile for flush or countersunk installation
• 2 mm hex socket drive for standard Allen key or hex bit installation
• M3x0.5 metric thread with full threading along the 20 mm length
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Conforms to DIN 7991 fastener standard for dimensional consistency

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for any metric countersunk hex socket application requiring an M3x0.5 thread and DIN 7991 flat head profile.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical technicians using a 2 mm hex key or hex socket bit. Countersunk holes should be machined to a 90-degree included angle to match the flat head geometry before installation. De-energize and lock out any equipment before accessing internal fastener locations. Do not substitute an incorrect drive size, as rounding the socket on a grade 12.9 fastener can make removal difficult.
