Value Collection 534202PR Flat Socket Cap Screw M12x1.75

Product Description

The VALUE COLLECTION 534202PR 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 carries full threading along its 45 mm overall length at an M12x1.75 thread pitch. Grade 12.9 designates the highest common property class for metric fasteners, indicating high tensile strength and resistance to shear loads. The black oxide coating provides mild corrosion resistance and reduces light reflection. This fastener is installed by machinists, millwrights, maintenance technicians, and fabricators wherever a flush or countersunk socket-drive fastener is required.

This screw is suited for applications where the fastener head must sit flush with or below the mating surface, such as machine frames, fixtures, tooling plates, and precision assemblies. The M12x1.75 metric coarse thread and DIN 7991 standard make it a direct fit for metric-dimensioned components across industrial, manufacturing, and mechanical maintenance environments. The 12.9 material grade is appropriate for high-stress joints that standard cap screws cannot satisfy.

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
• 8 mm hex socket drive for high torque input with a standard Allen key or hex bit
• M12x1.75 metric coarse thread, fully threaded along 45 mm overall length
• Black oxide finish provides mild corrosion resistance and low-reflectance appearance
• Conforms to DIN 7991 fastener standard for dimensional consistency

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw for use in any M12x1.75 threaded application requiring a 90-degree countersunk head profile and grade 12.9 strength class.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using an 8 mm hex key or hex bit driver. Verify that the mating component features a properly machined 90-degree countersink to achieve full head seating and load transfer. Torque to the fastener manufacturer or joint-design specification for grade 12.9 hardware. Inspect threads for contamination or damage before installation and apply thread lubricant or threadlocker only as specified by the engineering requirement.
