Holo-krome 76585 Hex Socket Cap Screw M30 X 3.50 Metric

Product Description

The HOLO-KROME 76585 is a fully threaded hex socket cap screw in M30 x 3.50 metric thread, designed for high-load mechanical and structural fastening applications. Manufactured from alloy steel with a Material Grade 12.9 rating, it delivers exceptional tensile and yield strength suited for demanding industrial and trade use. The screw features a black oxide coating that provides mild corrosion resistance and a clean, low-reflectance finish. The 90 mm length under head accommodates thick assemblies and flanged joints where positive clamping force is critical. Installation requires a hex socket driver or Allen key of the appropriate metric size. This fastener meets ANSI B1.13M, ISO 4762, and ISO 898-1 standards.

The HOLO-KROME 76585 is used across industrial machinery, heavy equipment assembly, structural steel fabrication, and mechanical systems requiring high-strength metric fasteners. The M30 thread size places this fastener in heavy-duty service categories typical of commercial and industrial installations rather than light residential work. Maintenance technicians, millwrights, pipefitters, and heavy equipment mechanics frequently specify Grade 12.9 alloy steel socket cap screws for critical joint applications where standard hardware-grade fasteners would be inadequate.

Key Features

• M30 x 3.50 metric thread - heavy-duty size for high-load structural and mechanical joints
• 90 mm length under head - accommodates thick flanges and deep-stack assemblies
• Fully threaded shank for maximum thread engagement along the entire fastener length
• Grade 12.9 alloy steel construction - among the highest standard strength grades for metric fasteners
• Black oxide finish for mild corrosion resistance and reduced surface reflectance
• Meets ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style and aftermarket replacement hex socket cap screw for M30 x 3.50 metric threaded applications conforming to ISO 4762 socket head cap screw geometry and ISO 898-1 mechanical property requirements.

Installation Notes

Installation requires a properly sized metric hex socket key or driver rated for Grade 12.9 fastener torque loads - use calibrated torque tooling appropriate to the joint specification. Always degrease or treat mating surfaces per the assembly specification before installation. De-energize or lock out any equipment before servicing fastened assemblies in electrical or mechanical systems. Do not substitute a lower-grade fastener in any joint originally designed for Grade 12.9 hardware.
