Holo-krome 76479 Hex Socket Cap Screw M16 X 2.00 140mm

Product Description

The HOLO-KROME 76479 is a metric hex socket cap screw designed for high-load fastening applications in industrial, mechanical, and equipment assembly environments. The M16 x 2.00 thread profile and 140 mm length under head make it well suited for heavy structural connections where precision threading and clamping force are critical. Manufactured from alloy steel to material grade 12.9, this screw delivers exceptional tensile strength. The black oxide finish provides a baseline level of corrosion resistance and reduces light reflection, making it a standard choice for machinery, tooling fixtures, and fabricated assemblies. Installation is performed with a hex socket driver or Allen wrench.

This screw is used in industrial maintenance, machine assembly, and fabrication settings where metric fasteners are specified. The partially threaded shank allows for controlled clamping without thread engagement through the full grip length, which is important in precision bolted joints. It is appropriate for both OEM assembly and MRO replacement applications requiring a Grade 12.9 alloy steel fastener conforming to metric standards.

Key Features

• M16 x 2.00 metric thread for heavy-duty clamping applications
• 140 mm length under head with partial threading for controlled grip
• Grade 12.9 alloy steel construction for high tensile and proof load ratings
• Black oxide finish for corrosion resistance and low-reflectivity appearance
• Hex socket drive for high-torque installation with standard Allen tooling
• Conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as an OEM-style and MRO replacement metric hex socket cap screw for applications requiring an M16 x 2.00 thread, 140 mm length under head, and Grade 12.9 alloy steel per DIN 912 and ISO 4762 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and the appropriate hex socket bit. Always de-energize and lock out equipment before servicing fastened assemblies. Do not substitute a lower material grade fastener in joints originally specified for Grade 12.9. Follow applicable equipment manufacturer torque specifications for the joint design.
