Value Collection 43172 M10x1.5 Flat Socket Cap Screw 12.9

Product Description

The VALUE COLLECTION 43172 is a metric flat socket cap screw designed for flush or countersunk fastening applications in industrial and mechanical assemblies. Sized at M10x1.5 with an overall length of 50 millimeters, it uses a 6 millimeter hex socket drive and features a 90-degree flat head profile that seats flush with the mating surface when properly installed. The fastener is partially threaded and manufactured from 12.9 grade alloy steel, placing it among the highest strength classifications for metric fasteners. A black oxide finish provides a measure of corrosion resistance and reduces light reflection in precision assemblies. This screw is installed by machinists, maintenance technicians, and mechanical assemblers working with metric hardware.

This fastener is suited for high-load, close-tolerance applications where a low-profile or flush head is required. Typical uses include machine tool fixtures, industrial equipment frames, jigs, and structural mechanical assemblies where the M10x1.5 thread pitch and 12.9 material grade are specified. Its partial threading is appropriate for clamping applications where a smooth shank is needed in the grip zone. This fastener conforms to DIN 7991 and uses the metric thread standard.

Key Features

• 12.9 alloy steel construction delivers high tensile and proof load strength for demanding fastening applications
• 90-degree flat head with hex socket drive allows flush or countersunk installation in prepared holes
• 6 millimeter hex socket drive compatible with standard metric hex keys and socket tooling
• Partial threading provides an unthreaded shank in the grip zone for clamping and alignment
• Black oxide finish for reduced reflectivity and moderate corrosion resistance
• Conforms to DIN 7991 fastener standard for dimensional consistency

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for use in any application specifying an M10x1.5 thread, 50 millimeter overall length, and 12.9 grade alloy steel. Compatible with standard metric countersunk hole patterns prepared for a 90-degree flat head profile.

Installation Notes

Installation requires a 6 millimeter hex key or socket driver torqued to the value specified in the applicable engineering standard for 12.9 grade M10 fasteners. Ensure the receiving material is prepared with a properly dimensioned countersunk hole per DIN 7991 specifications before installation. De-energize and lock out any equipment before servicing fasteners on live machinery per applicable safety procedures. Do not substitute a lower-grade fastener in applications where 12.9 grade is specified by design.
