Holo-krome 76392 Hex Socket Cap Screw M12 X 1.75 Alloy Steel

Product Description

The HOLO-KROME 76392 is a metric hex socket cap screw designed for high-strength fastening applications in industrial and mechanical assemblies. It features an M12 x 1.75 thread size with a 65 mm length under head and is partially threaded, making it suitable for applications requiring a bearing shoulder. Manufactured from alloy steel at material grade 12.9, it delivers exceptional tensile and proof-load strength. The black oxide finish provides corrosion inhibition and reduces light reflection in precision assemblies. A licensed mechanic, millwright, or maintenance technician is the typical installer for this fastener.

This screw is used in industrial machinery, tooling fixtures, structural mechanical assemblies, and equipment maintenance contexts where a Grade 12.9 metric fastener is specified. The internal hex drive accepts a standard metric hex key or hex bit driver. Its partial threading allows it to seat against an unthreaded shank for load transfer in close-tolerance bores. Applications span manufacturing, heavy equipment, and general mechanical maintenance where ANSI B1.13M or DIN 912 fastener standards are required.

Key Features

• M12 x 1.75 thread size with 65 mm length under head for precise fastening depth
• Grade 12.9 alloy steel construction for maximum tensile strength in high-load applications
• Partially threaded shank provides a load-bearing shoulder for close-tolerance assemblies
• Black oxide coating offers corrosion inhibition and a low-reflectance finish
• Internal hex drive for secure torque application with standard metric hex tools
• Meets ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style metric hex socket cap screw conforming to DIN 912 and ISO 4762 standards, suitable for M12 x 1.75 threaded holes in industrial and mechanical assemblies requiring Grade 12.9 fastener specifications.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a calibrated metric hex key or hex bit with an appropriate torque wrench. Always de-energize and lock out equipment before performing fastener service on powered machinery. Grade 12.9 fasteners should not be substituted with lower-grade hardware in high-load or safety-critical joints. Follow applicable machinery manufacturer torque specifications and relevant industry standards when determining final installation torque.
