Holo-krome 87124 Flat Socket Cap Screw M8x1.25

Product Description

The HOLO-KROME 87124 is a metric flat socket cap screw designed for flush or countersunk fastening applications in industrial and mechanical assemblies. It features a 90-degree flat head driven by a 5 mm hex socket and is fully threaded along its 16 mm overall length. Manufactured from 12.9 grade alloy steel with a black oxide finish, it delivers high tensile strength and moderate corrosion resistance. This screw is specified to ANSI B1.13M and ISO 10642 fastener standards, making it suitable for precision-critical assemblies where dimensional accuracy and material grade matter. Installation is typically performed by machinists, maintenance technicians, and mechanical assemblers.

This screw is well suited for applications requiring a low-profile, countersunk head that sits flush with or below the mating surface. Common use cases include machine tool fixtures, jigs, structural brackets, and equipment housings where head protrusion would interfere with mating components or clearance requirements. The M8x1.25 thread size and fully threaded body provide secure engagement across a range of material thicknesses. Minimum order quantity is 100 pieces.

Key Features

• 90-degree flat head with 5 mm hex socket drive for countersunk installations
• M8x1.25 metric thread, fully threaded over 16 mm overall length
• 12.9 grade alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Conforms to ANSI B1.13M and ISO 10642 fastener standards
• Thread fit class 4G for consistent metric thread engagement

Compatibility

Designed as a standard metric countersunk fastener compatible with M8x1.25 tapped holes in machinery, fixtures, and structural assemblies conforming to ISO 10642 and ANSI B1.13M specifications.

Installation Notes

Installation requires a 5 mm hex key or socket driver. Ensure the mating material is drilled and countersunk to the correct 90-degree angle before driving the screw. Power down or de-energize any equipment before fastener service on live assemblies. Follow applicable torque guidelines for 12.9 grade M8 fasteners as specified by the equipment manufacturer or relevant industry standards.
