Value Collection 534080P M6x1 Flat Socket Cap Screw 12.9

Product Description

The VALUE COLLECTION 534080P is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Built to DIN 7991 standard, this screw features a 90-degree flat head driven by a 4.00 mm hex socket. The fastener is fully threaded along its 20 mm overall length with an M6x1 thread pitch. Manufactured from grade 12.9 alloy steel, it delivers high tensile strength suitable for demanding mechanical assemblies. The black oxide finish provides a moderate level of corrosion resistance and reduces light reflection, making it a common choice in precision machine building, tooling fixtures, and equipment fabrication.

This flat socket cap screw is suited for metric fastening applications in industrial, manufacturing, and mechanical maintenance environments. The countersunk 90-degree head allows the fastener to sit flush with or below the surface of the mating material, which is critical in assemblies with tight clearance requirements or moving components. It is commonly installed by machinists, maintenance technicians, and mechanical assemblers working on machine frames, jigs, fixtures, and structural brackets where a low-profile fastener head is required.

Key Features

• DIN 7991 standard flat socket cap screw for consistent metric fitment
• 90-degree flat head profile for flush or countersunk installation
• 4.00 mm hex socket drive for precise torque application
• Grade 12.9 alloy steel construction for high tensile and shear strength
• Fully threaded M6x1 shank over 20 mm overall length
• Black oxide finish reduces glare and offers light surface protection

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M6x1 threaded holes in industrial machinery, tooling fixtures, and mechanical assemblies requiring a countersunk fastener.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician using a calibrated 4.00 mm hex key or socket drive. Ensure the receiving hole is properly countersunk to the correct 90-degree angle before installation to achieve a flush seating surface. Verify thread condition and clean any debris from the threaded bore before driving the fastener. Apply appropriate thread-locking compound or torque specifications per the equipment manufacturer guidelines for the assembly.
