Holo-krome 76416 Hex Socket Cap Screw M12 X 1.75 Alloy Steel

Product Description

The HOLO-KROME 76416 is a metric hex socket cap screw designed for high-strength fastening in precision mechanical assemblies. It features an M12 x 1.75 thread profile with a 110 mm length under head and is partially threaded to allow controlled clamping in through-hole and counterbored applications. Manufactured from alloy steel to material grade 12.9, it delivers exceptional tensile and proof load capacity. The black oxide coating provides moderate corrosion resistance and reduces surface galling during installation. This fastener is installed using a hex socket driver and is suited for machine builders, millwrights, and maintenance technicians working on industrial equipment.

This screw is used in applications requiring high-clamp-load fastening in metal-to-metal joints, structural machine frames, hydraulic manifolds, and precision fixtures. The partial threading engages the full thread length in the tapped hole while leaving the shank smooth in the clearance bore, which is standard practice for dowel-fit and tight-tolerance assemblies. Typical installers include industrial maintenance technicians, mechanical assemblers, and OEM machine builders working in manufacturing and process equipment environments.

Key Features

• M12 x 1.75 thread size with 110 mm length under head for deep-engagement fastening
• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Partially threaded shank for controlled clamping in clearance-bore applications
• Black oxide finish for moderate corrosion resistance and reduced galling
• Hex socket drive for torque application with standard hex key or socket tooling
• Conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style and replacement metric hex socket cap screw for industrial machinery, fixtures, and mechanical assemblies requiring an M12 x 1.75 partially threaded grade 12.9 fastener.

Installation Notes

Installation is performed by qualified mechanical assemblers or maintenance technicians using a calibrated torque wrench and the appropriate hex socket driver. De-energize and lock out all equipment before disassembling any fastened joints. Grade 12.9 fasteners require precise torque control to achieve proper clamp load without exceeding material yield limits; consult the equipment manufacturer torque specification table before installation. Do not substitute a lower-grade fastener in a joint designed for grade 12.9.
