Holo-krome 69458 Low Socket Cap Screw M8x1.25 16mm

Product Description

The HOLO-KROME 69458 is a metric low socket cap screw designed for applications where standard cap screw head height creates a clearance problem. It features an M8x1.25 coarse thread, a 16mm length measured under the head, and a 5mm head height — roughly half the profile of a standard socket cap screw. The hex socket drive accepts a 6mm hex key. Manufactured from alloy steel with a black oxide finish, it carries a property class 10.9 rating, indicating high tensile strength suitable for demanding mechanical assemblies. Licensed machinists, millwrights, and maintenance technicians are the typical installers.

This fastener is used in precision mechanical assemblies, machine tool fixtures, automotive components, and industrial equipment where a low-profile head is required to avoid interference with adjacent parts or mating surfaces. The fully threaded and partially threaded configuration options accommodate both through-hole and blind-hole installations. Its metric dimensioning makes it appropriate for equipment built to international or OEM metric standards.

Key Features

• Low socket cap head profile — 5mm head height reduces clearance conflicts in tight assemblies
• M8x1.25 coarse thread with 6G thread fit class for consistent engagement and fit
• Property class 10.9 alloy steel for high tensile and proof load strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 6mm hex socket drive compatible with standard metric hex keys and hex bit drivers
• Conforms to ANSI B1.13M and ISO 4762 fastener standards

Compatibility

Designed as an OEM-style metric fastener for use in assemblies requiring an M8x1.25 low socket cap screw to ANSI B1.13M or ISO 4762 specifications.

Installation Notes

Installation requires a 6mm hex key or hex socket driver. Verify the tapped hole thread class and depth before installation to ensure proper engagement. Do not exceed the rated property class torque specifications for class 10.9 M8 fasteners as published in applicable standards. Black oxide finish offers limited corrosion protection — apply thread lubricant or anti-seize compound if the installation environment involves moisture or dissimilar metals.
