Holo-krome 76384 Hex Socket Cap Screw M12x1.75 55mm

Product Description

The HOLO-KROME 76384 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and equipment assembly settings. Manufactured from alloy steel with a black oxide coating, this fastener carries a material grade of 12.9, placing it among the highest tensile-strength classifications available for metric screws. The M12 x 1.75 thread size and 55 mm length under head make it well suited for applications requiring a secure, corrosion-resistant connection. Installation requires a standard hex key or Allen driver. Electricians, millwrights, and mechanical contractors regularly specify 12.9-grade fasteners where joint integrity under load is critical.

This screw is used in machinery assembly, structural fastening, die and mold work, hydraulic equipment, and general industrial applications where a high-clamp-load fastener is required. Its fully threaded shank ensures consistent thread engagement across the entire grip length, making it appropriate for thinner material stacks and close-tolerance bolt patterns. The black oxide finish provides mild corrosion resistance and reduces surface glare in finished assemblies.

Key Features

• Material grade 12.9 alloy steel for maximum tensile and proof-load strength
• Black oxide coating provides mild corrosion resistance and a clean, low-glare finish
• Fully threaded shank for consistent engagement in thinner material applications
• Hex socket drive (Allen key) for high-torque fastening in confined spaces
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as an OEM-style and replacement metric hex socket cap screw for M12 x 1.75 threaded applications conforming to DIN 912 and ISO 4762 specifications.

Installation Notes

Installation is performed with a properly sized hex key or Allen driver rated for the applied torque. Always verify thread engagement depth and mating material hardness before installation, as 12.9-grade fasteners can strip lower-grade tapped holes under full preload. De-energize or shut down any equipment before fastener replacement or assembly work. Follow applicable machinery safety standards and torque specifications from the equipment OEM when tightening.
