Holo-krome 76593 Hex Socket Cap Screw M30 X 3.50 Alloy Steel

Product Description

The HOLO-KROME 76593 is an M30 x 3.50 hex socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. Manufactured from alloy steel to material grade 12.9, it delivers exceptional tensile strength for demanding fastening requirements. The black oxide coating provides mild corrosion resistance and reduces light reflection during assembly. With a 140 mm length under head and a hex socket drive, this fastener is installed with a standard hex key or Allen-type driver. It conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 standards, making it suitable for use in precision-tolerance metric assemblies.

This screw is used in heavy-duty machine building, tooling fixtures, hydraulic component mounting, and general industrial fabrication where a metric grade 12.9 cap screw is specified. The M30 thread size and 140 mm under-head length suit thick-section clamping and deep through-bolt applications. Maintenance technicians, machine builders, and industrial contractors regularly specify this fastener when maximum clamp load is required in a compact-head format. It is sold individually and can be ordered in single-unit quantities.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load ratings
• Black oxide finish provides mild corrosion resistance and a clean appearance
• Hex socket drive compatible with standard metric Allen keys and socket bits
• Conforms to ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards
• 140 mm length under head suits thick-section and deep-reach clamping applications

Compatibility

Designed as a standard metric hex socket cap screw for use in any application specifying an M30 x 3.50 pitch, grade 12.9 fastener per ISO 4762 or ANSI B1.13M.

Installation Notes

Installation should be performed by a qualified mechanic or industrial technician familiar with metric fastener torque requirements for grade 12.9 hardware. Ensure mating threads are clean and free of debris before installation. Do not mix metric and unified thread fasteners in the same assembly. Consult the equipment manufacturer or applicable torque specification table for proper clamp-load values before final tightening.
