Holo-krome 76056 M4 X 0.70 Hex Socket Cap Screw 8mm

Product Description

The HOLO-KROME 76056 is a metric hex socket cap screw designed for high-strength fastening applications requiring a compact, recessed-drive profile. It features an M4 x 0.70 thread form and an 8 mm length under head, with full threading along the shank. Manufactured from alloy steel at material grade 12.9, it delivers high tensile and proof load capacity. The black oxide coating provides moderate corrosion resistance and reduces light reflection, making it well-suited for precision assemblies, tooling, and mechanical components. Licensed trades and production maintenance technicians typically specify this fastener where space is limited and a flush or countersunk hex-drive is required.

This fastener is used in a broad range of industrial, mechanical, and equipment assembly applications. The M4 thread size and 8 mm length under head suit it for light structural and precision component fastening in both OEM manufacturing and field service contexts. It is fully threaded, which allows engagement across the entire fastened joint. Typical installations include machine frames, fixtures, guards, and similar assemblies where a socket head profile is preferred over an external hex. Sold individually per package, with a minimum order quantity of 100 pieces.

Key Features

• M4 x 0.70 metric thread form, fully threaded shank
• 8 mm length under head for compact, space-constrained fastening
• Grade 12.9 alloy steel construction for high tensile strength
• Black oxide finish for moderate corrosion resistance and low reflectivity
• Hex socket (internal hex) drive for high torque transfer in tight spaces
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as an OEM-style and general-purpose replacement hex socket cap screw for metric M4 x 0.70 threaded applications conforming to DIN 912 and ISO 4762 dimensional standards.

Installation Notes

Installation requires an appropriately sized metric hex key or socket bit driver; consult the fastener manufacturer or relevant standard for applicable torque values based on grade and joint conditions. Ensure mating threads are clean and free of debris before installation. Do not mix metric and unified thread fasteners in the same assembly. Grade 12.9 fasteners should not be substituted with lower-grade hardware without engineering review.
