Holo-krome 76080 Hex Socket Cap Screw M4 X 0.70 25mm Grade 12.9

Product Description

The HOLO-KROME 76080 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. Manufactured from alloy steel at material grade 12.9, it delivers the tensile strength required for demanding clamping and structural connections. The M4 x 0.70 thread profile with a 25 mm length under head makes it well-suited for precision assemblies where a clean, recessed drive is needed. The black oxide coating provides a degree of corrosion resistance and reduces light reflection in service environments. Installation requires a hex key or Allen driver. This screw is sold as an individual unit with a minimum order quantity of 100 pieces.

This fastener is appropriate for residential and commercial mechanical assemblies, machinery, HVAC equipment mounting, electrical enclosure hardware, and general industrial fabrication. The fully threaded shank allows maximum thread engagement across the full 25 mm length, making it effective in through-hole and blind-hole applications where consistent clamping force is required. It is commonly installed by millwrights, mechanical contractors, HVAC technicians, and industrial maintenance professionals working within metric fastener specifications.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• M4 x 0.70 metric thread with 25 mm length under head, fully threaded
• Black oxide finish for mild corrosion resistance and reduced glare
• Hex socket drive for recessed installation with Allen key or hex bit driver
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a standard metric hex socket cap screw compatible with M4 x 0.70 threaded assemblies conforming to DIN 912 and ISO 4762 dimensional specifications.

Installation Notes

Installation is performed using a correctly sized hex key or Allen driver to prevent rounding of the socket drive. Confirm thread engagement depth and hole preparation meet the fastener standard specifications before torquing. De-energize and lock out any equipment before replacing or installing fasteners in powered assemblies. Do not substitute grade 12.9 screws in applications specifying a different material grade without engineering review.
