Holo-krome 87100 M6x1 Flat Socket Cap Screw 12.9 Alloy Steel

Product Description

The HOLO-KROME 87100 is a metric flat socket cap screw engineered 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 25 mm overall length. Built from 12.9 grade alloy steel with a black oxide finish, the 87100 delivers high tensile strength and moderate corrosion resistance in a low-profile configuration. This fastener conforms to ANSI B1.13M and ISO 10642 standards, making it a reliable choice for precision mechanical assemblies. It is typically installed by machinists, maintenance technicians, and industrial assembly professionals.

The 87100 is suited for use in machine tool fixtures, equipment enclosures, precision jigs, and structural assemblies where the fastener head must sit flush with or below the mating surface. The M6x1 thread size and fully threaded shank make it appropriate for through-hole and tapped-hole applications in metal components. The black oxide finish reduces light reflection and provides a degree of surface protection in controlled environments. This screw is supplied individually per package with a minimum order quantity of 100 pieces.

Key Features

• 90-degree flat head profile for flush countersunk installations
• 4 mm hex socket drive for precise torque application
• 12.9 grade alloy steel construction for high tensile load capacity
• Black oxide finish for reduced reflectivity and mild corrosion resistance
• Fully threaded along entire 25 mm length
• Conforms to ANSI B1.13M and ISO 10642 fastener standards

Compatibility

Designed as an OEM-style metric flat socket cap screw for use in M6x1 tapped or through-hole applications conforming to ISO 10642 and ANSI B1.13M specifications.

Installation Notes

Installation is performed using a 4 mm hex key or hex socket driver. Ensure the mating countersink is machined to a 90-degree included angle to achieve full head seating. Verify thread fit class 4G compatibility with the receiving thread before installation. Follow applicable torque guidelines for 12.9 grade M6 fasteners as specified by your assembly engineering standards.
