Value Collection 534068PR Flat Socket Cap Screw M5x0.8

Product Description

The VALUE COLLECTION 534068PR is a metric flat socket cap screw manufactured from 12.9 grade alloy steel with a black oxide finish. It features a 90-degree flat head and a hex socket drive, making it well-suited for flush or countersunk fastening applications where head clearance is critical. The M5x0.8 thread pitch and 50 mm overall length provide a reliable fastening solution for precision assemblies. Partial threading along the shank helps maintain shear strength across joined materials. This screw is commonly installed by machinists, millwrights, and maintenance technicians working with metal fabrication, tooling, machinery, and structural assemblies.

This flat socket cap screw is used in applications requiring a low-profile, countersunk fastener with high tensile strength. The 12.9 material grade delivers exceptional clamping force, making it appropriate for high-stress mechanical assemblies, jigs, fixtures, and precision equipment. The black oxide finish provides moderate corrosion resistance and reduces light reflection in sensitive environments. It conforms to DIN 7991 fastener standards, ensuring dimensional consistency for metric engineering applications across industrial, commercial, and OEM manufacturing contexts.

Key Features

• 12.9 grade alloy steel construction for high tensile and yield strength
• 90-degree flat head profile for flush countersunk installations
• Hex socket drive accepts standard 3 mm hex key or Allen wrench
• Black oxide finish for moderate corrosion resistance and low reflectivity
• Partial threading preserves shank shear strength in load-bearing joints
• Conforms to DIN 7991 fastener standard for consistent metric dimensions

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for countersunk M5 threaded holes in industrial machinery, precision tooling, fixtures, and fabricated metal assemblies requiring a high-strength metric fastener.

Installation Notes

Installation is performed by machinists, maintenance technicians, or assembly personnel using a 3 mm hex key or Allen driver. Ensure the mating countersunk hole is machined to the correct 90-degree angle to achieve proper head seating and avoid stress concentration. Verify thread engagement depth meets engineering requirements before final torque. Always follow applicable fastener and machinery safety standards for the specific assembly.
