Value Collection 534148PR M10x1.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534148PR is a metric flat socket cap screw manufactured from 12.9 grade alloy steel with a black oxide finish. The 90-degree flat head profile sits flush with or below the mating surface when fully seated, making it well suited for applications where a protruding head is not acceptable. Drive engagement is through a 6 mm hex socket. The fastener is fully threaded along its 20 mm overall length and conforms to DIN 7991. It is installed by machinists, millwrights, and assembly technicians working on precision mechanical assemblies, jigs, fixtures, and industrial equipment.

This screw is used in metric mechanical assemblies where a countersunk, flush-mount fastener is required. The M10x1.5 thread size and 20 mm length are common in medium-duty structural and machine-component applications. The black oxide finish provides a mild level of corrosion resistance suitable for indoor and controlled-environment use. The DIN 7991 standard makes this fastener directly interchangeable with other components sourced to the same specification. Typical users include maintenance technicians, fabricators, and OEM assembly operations.

Key Features

• 12.9 grade alloy steel construction for high tensile and proof-load strength
• 90-degree flat head seats flush with the work surface for low-profile assemblies
• 6 mm hex socket drive for standard Allen key or hex bit engagement
• Fully threaded along the 20 mm overall length for maximum thread engagement
• Black oxide finish reduces surface reflectivity and provides mild corrosion protection
• Manufactured to DIN 7991 standard for consistent dimensional interchangeability

Compatibility

Designed as a DIN 7991-compliant replacement or standard-fit fastener for metric assemblies requiring an M10x1.5 countersunk hex socket cap screw with a 90-degree flat head profile.

Installation Notes

Installation is performed with a 6 mm hex key or hex bit driver. The mating hole must be countersunk to a 90-degree angle to achieve proper head seating and flush-surface results. Verify thread engagement depth in the receiving material before final torque to avoid stripping. On critical structural joints, consult published torque tables for 12.9 grade M10 fasteners and use a calibrated torque wrench.
