Value Collection A996731 Hex Socket Cap Screw M4x0.70 25pk

Product Description

The VALUE COLLECTION A996731 is a partially threaded hex socket cap screw designed for precision fastening applications in mechanical assemblies, fixtures, and equipment. Built to M4 x 0.70 metric thread specifications with a 70 mm length under head, this screw is manufactured from Grade 12.9 alloy steel, making it one of the highest-strength fastener grades available. The black oxide finish provides moderate corrosion resistance and reduces light reflection on exposed surfaces. Conforming to DIN 912 and ISO 898-1 standards, this screw suits high-load applications where dimensional consistency and material strength are critical. Sold in a package of 25.

This fastener is commonly used in industrial machinery, CNC equipment, hydraulic assemblies, tool and die work, and structural mechanical components. The M4 thread size and 70 mm under-head length make it appropriate for medium-depth through-bolt and tapped-hole applications where a flush or low-profile head is required. Partial threading allows for controlled clamping force distribution in precision-fit applications. Installers and machinists working in fabrication, maintenance, and OEM assembly are the primary users of this screw type.

Key Features

• Grade 12.9 alloy steel construction for high tensile and yield strength
• M4 x 0.70 metric thread with 70 mm length under head
• Partially threaded shank for precise clamping in tapped holes
• Hex socket drive for torque-controlled installation with Allen keys or hex bits
• Black oxide finish for reduced surface reflectivity and mild corrosion resistance
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any M4 x 0.70 tapped hole application across industrial, mechanical, and equipment assembly environments.

Installation Notes

Installation is performed by machinists, maintenance technicians, and mechanical assemblers using a correctly sized hex key or socket bit. Always ensure the mating tapped hole is clean and free of debris before threading. Do not exceed the rated torque for Grade 12.9 M4 fasteners as specified in the applicable engineering documentation for the assembly. Apply thread-locking compound or preload as required by the design specification.
