Holo-krome 87084 Flat Socket Cap Screw M6x1 Alloy Steel

Product Description

The HOLO-KROME 87084 is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 90-degree flat head with a 4 mm hex socket drive and is fully threaded along its 10 mm overall length. The screw is manufactured from 12.9 grade alloy steel and finished with black oxide for basic corrosion resistance. Thread size is M6x1, conforming to ANSI B1.13M and ISO 10642 standards with a 4G thread fit class. Machinists, toolmakers, and mechanical assembly technicians install this fastener where high tensile strength and a low-profile head seating are required.

This flat socket cap screw is suited for precision mechanical assemblies, fixtures, jigs, dies, and machine components where the head must sit flush with or below the workpiece surface. The 90-degree countersunk head geometry is standard for metric tooling and machine-tool applications across light and heavy industrial environments. Its 12.9 material grade indicates a high-strength fastener appropriate for demanding load-bearing joints in both OEM manufacturing and MRO maintenance settings.

Key Features

• 90-degree flat head seats flush in countersunk holes per ISO 10642
• 12.9 alloy steel material grade delivers high tensile and proof load strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 4 mm hex socket drive for standard Allen key or hex bit installation
• Fully threaded M6x1 shank over 10 mm overall length
• Conforms to ANSI B1.13M and ISO 10642 fastener standards

Compatibility

Designed as a metric countersunk socket cap screw conforming to ISO 10642, suitable for use in any M6x1 threaded countersunk hole meeting the 90-degree flat head seat specification.

Installation Notes

Installation requires a 4 mm hex key or hex socket bit. Ensure the mating countersink is machined to a 90-degree included angle before seating the fastener. Torque to the value specified by the joint designer based on material grade and clamping requirements. Do not mix metric and unified thread systems in the same assembly.
