Holo-krome 69578 Low Socket Cap Screw M12x1.75 60mm

Product Description

The HOLO-KROME 69578 is a metric low socket cap screw designed for applications where standard cap screw head height creates clearance problems. Built from alloy steel with a black oxide finish, it carries a material grade of 10.9, indicating high tensile strength suited for demanding mechanical assemblies. The fastener measures M12x1.75 in thread size with a 60mm length under head and accepts a 10mm hex key drive. It is partially threaded along the shank. Installation is performed by maintenance technicians, millwrights, and mechanical assemblers working on equipment where tight tolerances or recessed mounting surfaces are required.

This screw is used in industrial machinery, structural assemblies, and mechanical equipment where metric fasteners are specified. The low-profile head keeps the fastener below or flush with surrounding surfaces, making it well suited for jigs, fixtures, tooling plates, and machine guarding. The black oxide finish provides mild corrosion resistance and reduces light reflection, which is useful in precision tooling and optical or robotic equipment environments. The M12 thread size and 10.9 grade make it appropriate for medium-to-high clamping force requirements in metalworking and fabrication settings.

Key Features

• Low socket cap head profile for clearance-sensitive installations
• M12x1.75 metric thread, conforming to ANSI B1.13M standard
• Material grade 10.9 alloy steel for high tensile and proof load strength
• Black oxide finish for mild corrosion resistance and low reflectivity
• Partially threaded shank for precise clamping and shoulder-style engagement
• 10mm hex socket drive for standard Allen key or hex bit installation

Compatibility

Designed as an OEM-style and replacement metric fastener for industrial machinery, fixtures, and mechanical assemblies specifying M12x1.75 low socket cap screws to ANSI B1.13M.

Installation Notes

Install and remove using a 10mm hex key or hex bit driver; use of an undersized key risks rounding the socket. Ensure mating threaded holes are tapped to M12x1.75 metric specification and are clean and free of debris before installation. Apply thread lubricant or thread-locking compound as specified by the equipment manufacturer. Follow applicable industry torque guidelines for grade 10.9 M12 fasteners when final tightening.
