Value Collection 43173 Flat Socket Cap Screw M10x1.5

Product Description

The VALUE COLLECTION 43173 is a metric flat socket cap screw designed for applications requiring a low-profile, flush-seating fastener. It features a 90-degree countersunk flat head driven by a 6 mm hex socket. The screw is manufactured from 12.9 grade alloy steel, which is among the highest strength grades available for metric fasteners. A black oxide finish provides mild corrosion resistance and a consistent dark appearance. The M10x1.5 thread designation indicates a 10 mm nominal diameter with a 1.5 mm thread pitch. Overall length is 60 mm, fully threaded. This fastener conforms to DIN 7991 standard and is suited for machine assembly, structural mounting, and mechanical fabrication work performed by machinists, millwrights, and maintenance technicians.

This flat socket cap screw is used in applications where the fastener head must sit flush with or below the surface of the mating material. Typical installations include machinery frames, jigs, fixtures, tooling plates, and equipment housings. The hex socket drive allows torque to be applied in tight or recessed clearances where an open-end or box wrench cannot reach. The 12.9 alloy steel construction makes it appropriate for high-load, high-stress assemblies in industrial and manufacturing environments. Minimum order quantity is 25 pieces.

Key Features

• 90-degree flat countersunk head sits flush with or below the work surface
• 12.9 grade alloy steel provides high tensile and proof load strength
• 6 mm hex socket drive for use with standard Allen or hex key tooling
• Fully threaded along the 60 mm overall length for maximum thread engagement
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Conforms to DIN 7991 fastener standard for dimensional consistency

Compatibility

Designed as a standard metric replacement or stock fastener for any assembly requiring a DIN 7991 M10x1.5 flat socket cap screw in 12.9 alloy steel with black oxide finish.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or millwrights using a 6 mm hex key or Allen driver. Ensure the mating countersink angle is machined to 90 degrees to match the head geometry of this fastener. Clean threads and verify correct hole depth before driving. Do not exceed the rated clamp load for 12.9 grade hardware, and use calibrated torque tooling when specified by the assembly engineer.
