Holo-krome 69480 Low Socket Cap Screw M8x1.25 40mm

Product Description

The HOLO-KROME 69480 is a metric low socket cap screw designed for applications where a reduced head profile is required. It features an M8x1.25 coarse thread, a 40 mm length measured under the head, and is manufactured from grade 10.9 alloy steel with a black oxide finish. The 5 mm head height keeps the fastener below surrounding surfaces in tight or recessed installations. A 6 mm hex socket drive provides positive engagement for installation and removal torque. This fastener meets ANSI B1.13M and ISO 4762 standards and carries a 6G thread fit class, making it suitable for precision mechanical assemblies in industrial, tooling, and machinery applications.

This screw is used in applications where standard socket cap head clearance is insufficient, such as side-by-side bolt patterns, thin flanges, and close-tolerance assemblies. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it appropriate for both indoor mechanical assemblies and tooling fixtures. Maintenance technicians and machine builders working with metric fastener specifications will find this screw suitable for structural and clamping functions requiring grade 10.9 strength.

Key Features

• Low socket cap head profile at 5 mm head height for recessed or space-restricted installations
• Grade 10.9 alloy steel construction for high tensile and proof load strength
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• M8x1.25 coarse thread with 6G thread fit class for controlled engagement
• Meets ANSI B1.13M and ISO 4762 standards for metric socket cap screws
• Partially threaded shank for shear load capability and precise hole location

Compatibility

Designed as an OEM-style metric fastener for use in machinery, tooling fixtures, and mechanical assemblies requiring a low-profile M8 socket cap screw per ANSI B1.13M and ISO 4762.

Installation Notes

Installation requires a 6 mm hex key or hex socket driver. Verify that mating threaded holes conform to the 6G fit class tolerance before installation. Power down or de-energize any equipment before servicing fastened assemblies. Do not exceed the rated tensile strength of the fastener when applying torque, and always follow the equipment manufacturer's specified torque procedures.
