Holo-krome 76412 Hex Socket Cap Screw M12 X 1.75 Alloy Steel

Product Description

The HOLO-KROME 76412 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and maintenance assembly work. It features an M12 x 1.75 thread profile with a 100 mm length under head and partial threading along the shank. Manufactured from alloy steel at material grade 12.9, it delivers high tensile strength suited to demanding clamping loads. The black oxide finish provides mild corrosion resistance and reduces light reflection in finished assemblies. This fastener is installed using a standard hex key or Allen driver and is a common choice for machine builders, maintenance technicians, and industrial contractors.

The 76412 is used wherever a high-strength metric socket cap screw is required, including machine frames, gearboxes, hydraulic component mounting, fixtures, and structural steel subassemblies. Its partially threaded shank allows for precise shear load transfer through the unthreaded grip zone, making it well suited to applications where the fastener passes through a clearance hole before engaging a threaded bore. This screw conforms to ANSI B1.13M, DIN 912, and ISO 4762 standards, so it fits into internationally toleranced assemblies without modification.

Key Features

• M12 x 1.75 metric thread form, partially threaded shank for shear load applications
• 100 mm length under head provides generous grip range for thick material stacks
• Alloy steel construction at grade 12.9 for high tensile and proof load capacity
• Black oxide finish offers mild corrosion resistance and low-reflectance appearance
• Hex socket drive accepts standard metric Allen keys and hex bit drivers
• Conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-fit metric fastener for any assembly specifying a DIN 912 or ISO 4762 M12 x 1.75 socket cap screw at grade 12.9 with a 100 mm length under head.

Installation Notes

Installation should be performed by a qualified mechanic or assembly technician familiar with metric fastener torque requirements for grade 12.9 hardware. Always verify the mating thread is clean and free of debris before installation, and use calibrated torque equipment to achieve the design clamping load specified in the assembly documentation. Do not mix metric and unified inch fasteners in the same threaded bore. Applying a thread lubricant or anti-seize compound will alter torque-tension relationships and should only be done when called out by the engineering specification.
