Value Collection 534216PR Flat Socket Cap Screw M12x1.75

Product Description

The VALUE COLLECTION 534216PR 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 an 8 mm hex socket and is partially threaded along its 80 mm overall length. The M12x1.75 thread conforms to DIN 7991 and the metric thread standard, making it a precision fastener suited for flush or countersunk installations in high-load assemblies. Grade 12.9 alloy steel delivers high tensile strength for demanding structural and mechanical applications. Installation is performed by machinists, millwrights, and maintenance technicians working on industrial equipment, machine frames, and fabricated assemblies.

This fastener is designed for metric countersunk applications where a flush surface is required after installation. The 90-degree flat head seats fully into a matching countersunk hole, eliminating protrusion above the mating surface. Typical use cases include CNC machine components, hydraulic manifolds, jigs, fixtures, and structural steel fabrication. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision environments. This screw is sold individually but carries a minimum order quantity of 10 units.

Key Features

• Grade 12.9 alloy steel construction for high tensile strength in demanding applications
• 90-degree flat head with 8 mm hex socket drive for countersunk flush installations
• M12x1.75 metric thread conforming to DIN 7991 fastener standard
• Black oxide finish for mild corrosion resistance and low-reflectance surface
• Partially threaded shank for improved shear load performance
• 80 mm overall length suits deep countersunk and thick-material assemblies

Compatibility

Designed as an OEM-style replacement or standard metric fastener for any application requiring a DIN 7991 M12x1.75 flat socket cap screw in grade 12.9 alloy steel.

Installation Notes

Installation should be performed by a qualified machinist, millwright, or maintenance technician using a calibrated 8 mm hex key or socket driver. Ensure the mating countersunk hole is machined to the correct 90-degree angle and diameter before driving the fastener. De-energize and lock out all equipment per applicable OSHA lockout/tagout procedures before servicing any assembly. Do not substitute a lower-grade fastener in applications specified for grade 12.9.
