Value Collection 534206PR M12x1.75 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534206PR is a metric flat socket cap screw designed for applications requiring a low-profile, flush or countersunk fastener. Built to DIN 7991 standard, it features a 90-degree flat head with an 8 mm hex socket drive and is manufactured from grade 12.9 alloy steel, delivering high tensile strength for demanding structural and mechanical assemblies. The black oxide finish provides mild corrosion resistance and a clean appearance. At M12x1.75 thread size and 55 mm overall length with partial threading, this fastener suits high-load bolted joints where head clearance is limited. Installation is performed by machinists, millwrights, and maintenance technicians across industrial and OEM environments.

This screw is suited for use in machine frames, fixtures, tooling plates, and precision mechanical assemblies where a countersunk socket head is required to sit flush with or below the mating surface. The metric M12x1.75 thread pitch and grade 12.9 material classification make it appropriate for high-strength, high-clamp-load applications in industrial equipment manufacturing, automation systems, and heavy-duty fabrication. Partial threading allows precise engagement control in through-bolt and tapped-hole configurations.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• 90-degree flat head profile per DIN 7991 for flush or countersunk installations
• 8 mm hex socket drive for secure torque application with standard Allen keys or socket drivers
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Partial threading for controlled engagement in tapped blind or through holes
• Metric thread standard simplifies sourcing in metric-spec equipment environments

Compatibility

Designed as an OEM-style metric fastener replacement or new-installation component for machinery, fixtures, and assemblies requiring a DIN 7991 countersunk socket cap screw in M12x1.75 thread size.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a calibrated torque wrench and the correct 8 mm hex key or socket bit. Always verify that the mating hole is properly countersunk to the correct 90-degree angle before driving the fastener. Grade 12.9 fasteners must not be substituted with lower-grade hardware in high-load or safety-critical joints. Consult the equipment manufacturer torque specification table for the applicable clamp load target for M12 grade 12.9 fasteners.
