Holo-krome 69528 Low Socket Cap Screw M10x1.5 45mm

Product Description

The HOLO-KROME 69528 is a metric low socket cap screw engineered for applications where head clearance is limited. Manufactured from alloy steel to material grade 10.9, this fastener delivers high tensile strength in a reduced-profile head geometry. The black oxide finish provides mild corrosion resistance and a consistent matte appearance. The M10x1.5 coarse thread is partially threaded along a 45 mm length measured under the head, and the hex socket drive accepts an 8 mm hex key. Machinists, millwrights, and mechanical assemblers install this type of fastener in confined spaces where a standard socket cap head would interfere with adjacent components.

This screw is suited for precision mechanical assemblies, machine tool fixturing, jig and fixture fabrication, and industrial equipment maintenance. The low-profile head reduces the standoff height compared to a standard socket cap, making it a common choice in tight-clearance bolt patterns on machine bases, guards, and brackets. The 6.5 mm head height and 8 mm hex socket allow installation with standard metric hex keys or ball-end drivers in restricted access areas.

Key Features

• Low socket cap head profile — 6.5 mm head height for clearance-critical installations
• M10x1.5 coarse metric thread, 45 mm length under head, partially threaded
• Alloy steel at material grade 10.9 for high tensile and proof load performance
• Black oxide finish for mild corrosion resistance and reduced light reflection
• 8 mm hex socket drive compatible with standard metric hex keys and drivers
• Conforms to ANSI B1.13M and ISO 4762 fastener standards

Compatibility

Designed as a metric replacement or direct-fit fastener for M10x1.5 coarse thread applications requiring a low-profile socket cap head per ANSI B1.13M and ISO 4762.

Installation Notes

Install and remove using an 8 mm hex key or ball-end driver; avoid worn or undersized keys that can round the socket. Confirm thread class 6G fit with the mating tapped hole before final assembly. Verify proper torque using a calibrated torque wrench per the assembly specification for grade 10.9 fasteners. Black oxide alone provides limited corrosion protection — apply a compatible thread lubricant or sealant if the service environment requires additional protection.
