Import 6912 8X40 Low Socket Cap Screw M8x1.25 40mm

Product Description

The IMPORT 6912 8X40 is a metric low socket cap screw designed for applications requiring a reduced-profile head with high clamping strength. Manufactured from alloy steel with a black oxide finish, this fastener meets ANSI B1.13M standards and carries a material grade of 10.9, indicating a tensile strength of 120,000 psi. The M8x1.25 coarse thread and hex socket drive make it suitable for use in confined spaces where a standard cap screw head would interfere with surrounding components. It is installed using a 6mm hex key.

This screw is suited for mechanical assemblies, equipment fabrication, and maintenance applications where a low-profile fastener is required. The partially threaded shank, with 22mm of thread length on a 40mm body, provides a clamping zone free of thread engagement. The black oxide finish offers mild corrosion resistance and reduces light reflection, making it common in industrial, automotive, and precision equipment contexts. Installation is performed by machinists, maintenance technicians, and field service professionals working on metric-spec equipment.

Key Features

• Low socket cap head profile at 5mm head height reduces clearance requirements
• Grade 10.9 alloy steel construction with 120,000 psi tensile strength
• M8x1.25 coarse thread per ANSI B1.13M metric fastener standard
• Partially threaded with 22mm thread length on a 40mm fastener body
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Hex socket drive accepts a 6mm hex key for installation in tight spaces

Compatibility

Designed as a metric replacement or service fastener for any assembly specifying an M8x1.25 low socket cap screw per ANSI B1.13M, with a 40mm length under head and 22mm thread engagement.

Installation Notes

Installation requires a 6mm hex key or Allen driver. Ensure mating threads are clean and free of debris before driving the fastener. Apply thread lubricant or thread-locking compound as specified by the equipment manufacturer. Do not exceed the rated tensile strength of the fastener by over-torquing, and always follow the torque specifications provided by the equipment OEM for Grade 10.9 metric fasteners.
