Holo-krome 76376 Hex Socket Cap Screw M12 X 1.75 Alloy Steel

Product Description

The HOLO-KROME 76376 is a fully threaded hex socket cap screw designed for high-strength fastening in precision mechanical and structural assemblies. It carries an M12 x 1.75 metric thread with a 45 mm length under the head, and is manufactured from alloy steel at material grade 12.9 — one of the highest strength classes in the ISO fastener system. A black oxide finish provides mild corrosion resistance and reduces light reflection. This screw is tightened with a hex (Allen) drive, making it well suited for recessed installations where a standard hex head would not clear. Mechanical contractors, millwrights, and industrial maintenance technicians are the typical installers.

This screw is used across a broad range of industrial, mechanical, and commercial applications where a compact, high-clamping-force fastener is required. Typical uses include machinery frames, hydraulic components, gearboxes, flanges, and structural steel fabrication. The M12 thread size and 45 mm under-head length suit medium-to-heavy-duty connections in both OEM manufacturing and field maintenance contexts. It meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards, confirming dimensional and mechanical compliance for international and domestic specifications.

Key Features

• Grade 12.9 alloy steel construction for maximum tensile and proof load strength
• Fully threaded along the 45 mm under-head length for maximum thread engagement
• Hex socket drive allows installation in tight or recessed clearances
• Black oxide finish for mild corrosion resistance and a low-reflectance appearance
• Conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a metric hex socket cap screw to DIN 912 and ISO 4762 dimensional standards, making it a direct-fit replacement or OEM-style fastener in any application specifying an M12 x 1.75 grade 12.9 socket head cap screw.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with metric fastener torque requirements for grade 12.9 hardware. Always verify the mating threaded hole meets the same metric pitch and class before installation. Use a calibrated torque wrench with the correct hex key bit to achieve the required clamp load without over-torquing. Lubrication of the thread and under-head bearing surface is recommended when specified by the equipment manufacturer.
