Holo-krome 76594 Hex Socket Cap Screw M30 X 3.50 160mm

Product Description

The HOLO-KROME 76594 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features an M30 x 3.50 thread profile and a 160 mm (approximately 6.3 inches) length under head. Manufactured from alloy steel to material grade 12.9, this fastener delivers high tensile strength suitable for demanding load-bearing connections. The black oxide coating provides a degree of corrosion resistance and reduces surface reflectivity. It is driven with a hex (Allen) key socket tool. This fastener meets ANSI B1.13M, ISO 4762, and ISO 898-1 standards.

This cap screw is used in precision mechanical assemblies, heavy equipment, machine tools, hydraulic systems, and structural joints where high-clamp-load fasteners are required. The M30 x 3.50 thread size places it in the heavy-duty range, making it appropriate for large-bore flanges, press frames, industrial machinery, and similar applications requiring a high-grade metric socket fastener. Installation is typically performed by maintenance machinists, millwrights, or mechanical contractors working to engineered torque specifications.

Key Features

• M30 x 3.50 metric thread form per ANSI B1.13M and ISO 4762
• 160 mm length under head (approximately 6.3 inches)
• Alloy steel construction at material grade 12.9 for high tensile strength
• Black oxide finish for mild corrosion resistance and low-reflectivity surface
• Hex socket drive for high-torque installation with standard Allen key tooling
• Conforms to ISO 898-1 mechanical property requirements for fasteners

Compatibility

Designed as a standard metric hex socket cap screw for use in any application requiring an M30 x 3.50 thread size and 160 mm length under head per ISO 4762 dimensional specifications.

Installation Notes

Installation should be performed by a qualified machinist or mechanical tradesperson using a calibrated torque wrench and the correct hex key socket rated for M30 fasteners. Always consult the equipment manufacturer or applicable engineering documentation for the required torque specification before installation. Ensure mating threaded holes are clean, free of debris, and properly tapped to M30 x 3.50 before driving the fastener. De-energize and lock out all equipment before servicing any mechanical assembly.
