Value Collection 43149 M6x1 Flat Socket Cap Screw 12.9

Product Description

The VALUE COLLECTION 43149 is a metric flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies. The 90-degree flat head seats flush with or below the work surface when installed in a properly chamfered hole. Drive engagement is achieved through a 4 mm hex socket. The screw is manufactured from 12.9 grade alloy steel, which is among the highest strength grades available for metric fasteners, making it suitable for high-load and vibration-prone assemblies. A black oxide finish provides mild corrosion resistance and reduces surface glare. Overall length is 30 mm and the fastener is fully threaded along its entire shank.

This fastener is used across a wide range of industrial, mechanical, and OEM assembly applications where a low-profile, flush-mount fastening solution is required. Common installation environments include machine frames, fixtures, tooling plates, and precision equipment housings. The M6x1 thread pitch is a standard metric coarse thread, widely encountered in both light and heavy mechanical fabrication. Installation is performed by machinists, millwrights, maintenance technicians, and mechanical assemblers working to DIN 7991 or equivalent specifications.

Key Features

• 90-degree flat head for flush or countersunk installation
• 4 mm hex socket drive for standard Allen key or hex bit engagement
• 12.9 grade alloy steel for high tensile and proof load capacity
• Fully threaded shank along the entire 30 mm length
• Black oxide finish for mild corrosion resistance and low-glare surface
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as an OEM-style metric flat socket cap screw for use in any application requiring an M6x1 countersunk hex socket fastener conforming to DIN 7991.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 4 mm hex key or hex socket bit. The mating hole must be chamfered to the appropriate 90-degree countersink angle to allow proper head seating. Torque to the value specified by the engineering drawing or assembly standard for 12.9 grade M6 fasteners. Ensure the work piece is de-energized or de-pressurized before disassembling any fastened component in a live system.
