Holo-krome 87092 M6x1 Flat Socket Cap Screw 12.9 Alloy Steel

Product Description

The HOLO-KROME 87092 is a metric flat socket cap screw designed for flush or countersunk fastening applications requiring high tensile strength. Built from 12.9 grade alloy steel with a black oxide finish, this screw delivers superior clamping force in tight-tolerance assemblies where standard cap screws will not seat flush. The 90-degree flat head profile mates with standard countersunk holes, while the 4 mm hex socket drive allows precise torque application with a hex key. Fully threaded along its 16 mm overall length with an M6x1 thread form, it conforms to ANSI B1.13M and ISO 10642 standards. Licensed mechanical contractors, industrial maintenance technicians, and precision assembly professionals regularly specify this fastener.

This fastener is suited for machine frames, fixtures, tooling plates, and structural assemblies where a low-profile flush-mount connection is required. The M6x1 thread size and full threading make it appropriate for through-hole and tapped-hole installations in metal components. The black oxide finish provides mild corrosion resistance and reduces light reflection in optical or precision instrument assemblies. It is commonly used in manufacturing, industrial equipment, and mechanical assembly environments where high-grade metric fasteners are specified.

Key Features

• 12.9 alloy steel material grade for high tensile and proof load strength
• 90-degree flat head seats flush in standard countersunk holes per ISO 10642
• 4 mm hex socket drive for precise torque delivery with standard hex keys
• Fully threaded M6x1 over entire 16 mm length for maximum thread engagement
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Conforms to ANSI B1.13M and ISO 10642 fastener standards

Compatibility

Designed as an OEM-style metric flat socket cap screw for use in countersunk applications requiring an M6x1 thread pattern and 12.9 grade alloy steel per ISO 10642 and ANSI B1.13M specifications.

Installation Notes

Installation is performed by qualified mechanical assemblers or maintenance technicians using a 4 mm hex key or hex bit driver. Ensure the mating countersink angle is 90 degrees to achieve proper head seating and load distribution. Verify tapped hole depth and thread class compatibility before installation - this fastener carries a 4G thread fit class. De-burr and clean countersunk holes prior to fastener seating to prevent galling on the black oxide finish.
