Value Collection 534156PR M10x1.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534156PR is a metric flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. Manufactured from 12.9 grade alloy steel with a black oxide finish, this screw delivers high tensile strength suited to demanding mechanical assemblies. The 90-degree flat head seats into a countersunk hole to sit flush with or below the mating surface. Drive engagement is via a 6 mm hex socket. The M10x1.5 thread runs the full length of the 40 mm shank, providing maximum thread engagement across the joint.

This fastener is used in precision mechanical, tooling, and industrial assembly applications where a flush surface profile is necessary. Typical installations include machine frames, jigs, fixtures, molds, and structural brackets where protruding fastener heads would interfere with movement or mating components. The black oxide finish provides mild corrosion resistance and reduces light reflection in optical or tooling environments. This screw is installed by machinists, maintenance mechanics, and industrial assemblers working to metric fastener standards.

Key Features

• 12.9 alloy steel material grade provides high tensile and proof load strength
• 90-degree flat head profile for flush or countersunk installation
• 6 mm hex socket drive for precise torque application with standard hex keys
• Fully threaded M10x1.5 shank maximizes thread engagement
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a metric DIN 7991 flat socket cap screw for countersunk through-hole applications requiring an M10x1.5 thread pitch and 40 mm overall length in machinery, tooling, and industrial equipment.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a 6 mm hex key or socket driver. The mating hole should be countersunk to 90 degrees at the correct diameter to allow the head to seat flush. Verify the countersink depth and diameter before final torque to avoid head protrusion or over-seating. Follow applicable industry torque specifications for 12.9 grade M10 fasteners and confirm hole preparation meets design requirements before assembly.
