Holo-krome 76596 M30 Hex Socket Cap Screw Alloy Steel

Product Description

The HOLO-KROME 76596 is a metric hex socket cap screw engineered for high-strength fastening in industrial, mechanical, and structural applications. It features an M30 x 3.50 thread size with a 240 mm length under head, manufactured from alloy steel with a black oxide finish coating. The grade 12.9 material rating places this fastener at the highest end of the metric strength scale, making it appropriate for applications that require significant clamping force and resistance to mechanical stress. It is installed using a hex drive tool and is well-suited for heavy equipment assembly, tooling, and machine frame construction.

This screw is used in applications requiring a strong, recessed-drive fastener where a flush or low-profile head is necessary. Grade 12.9 alloy steel construction makes it a common choice in hydraulic machinery, industrial presses, mold-making equipment, and structural steel assembly. It conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 standards, ensuring dimensional and mechanical property consistency across precision-fit applications in manufacturing and maintenance environments.

Key Features

• M30 x 3.50 thread size with 240 mm length under head for deep-reach fastening
• Grade 12.9 alloy steel construction for maximum tensile and yield strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Hex socket drive for high-torque installation with standard hex keys or socket drivers
• Meets ANSI B1.13M, ISO 4762, and ISO 898-1 dimensional and material standards

Compatibility

Designed as a standard metric hex socket cap screw suitable for M30 x 3.50 threaded bores and clearance holes in industrial machinery, structural assemblies, and heavy-duty mechanical equipment where ISO 4762 fastener geometry is required.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated torque wrench and the appropriate hex key or socket driver sized for the M30 cap screw head. Always de-energize, depressurize, or lock out equipment before servicing fasteners on live machinery. Do not mix metric and imperial fasteners in the same threaded application. Follow equipment manufacturer torque specifications and applicable industry standards for proper clamping load.
