Value Collection 534128PR Flat Socket Cap Screw M8x1.25

Product Description

The VALUE COLLECTION 534128PR is a metric flat socket cap screw manufactured from grade 12.9 alloy steel with a black oxide finish. It features a 90-degree flat head driven by a 5 mm hex socket and is designed for flush or countersunk fastening applications where a low-profile head is required. The M8x1.25 thread and 60 mm overall length make this a common choice in precision mechanical assemblies, machine frames, and tooling fixtures. It conforms to DIN 7991 standards. Machinists, millwrights, and maintenance technicians install this fastener where a standard socket head cap screw would protrude above the mating surface.

This screw is suited for metric fastening applications in industrial machinery, automation equipment, dies, molds, and structural machine components. The partially threaded shank provides a bearing surface that resists shear loads in close-tolerance holes. The black oxide coating offers mild corrosion resistance and reduces light glare in tooling environments. It is sold individually with a minimum order quantity of 10 pieces.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• 90-degree flat head profile allows flush or countersunk installation
• 5 mm hex socket drive for standard hex key wrenches
• Partially threaded shank provides shear resistance in precision bores
• Black oxide finish for mild corrosion resistance and low reflectivity
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a DIN 7991 metric flat socket cap screw in M8x1.25 thread size, suitable for standard metric countersunk hole patterns in industrial machinery and mechanical assemblies.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 5 mm hex key or socket driver. Countersink the mating hole to the appropriate 90-degree angle before installation to ensure full head seating. Torque to the value specified in the equipment service documentation for grade 12.9 fasteners of this thread size. Always confirm hole depth and thread engagement before applying final torque.
