Value Collection 43150 M6x1 Flat Socket Cap Screw 12.9

Product Description

The VALUE COLLECTION 43150 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 90-degree flat head driven by a 4 mm hex socket and is fully threaded along its 35 mm overall length. Manufactured from 12.9 grade alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance in a low-profile form factor. It is suited for mechanical assemblies, jigs, fixtures, and precision equipment where head protrusion must be minimized. Installation is performed by machinists, millwrights, and maintenance technicians working to metric fastener standards.

This screw is used in metric fastening applications where a countersunk seat is required. The M6x1 thread pitch and 35 mm length make it a common choice for medium-duty clamping and structural connections in machine components, tooling plates, and industrial equipment. The black oxide finish reduces light reflection and provides a degree of surface protection in dry or lightly oiled environments. It conforms to DIN 7991 fastener standards.

Key Features

• 90-degree flat head profile for flush or countersunk seating
• 4 mm hex socket drive for precise torque application
• 12.9 alloy steel grade for high tensile and proof load strength
• Black oxide finish for reduced reflectivity and surface protection
• Fully threaded M6x1 shank at 35 mm overall length
• Conforms to DIN 7991 fastener standard

Compatibility

Designed for use in metric-threaded M6x1 countersunk holes conforming to DIN 7991 specifications, suitable for machine assemblies and tooling applications that require a flush fastener seating surface.

Installation Notes

Install using a 4 mm hex key or socket driver. Ensure the mating countersink is machined to the correct 90-degree included angle before installation. Do not exceed the torque rating appropriate for 12.9 grade M6 fasteners as specified in the applicable engineering standard. Apply a thread lubricant or anti-seize if required by the assembly specification.
