Value Collection MP42783 Hex Socket Cap Screw M12x1.75

Product Description

The VALUE COLLECTION MP42783 is a fully threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fabrication work, and industrial equipment. The screw features an M12 x 1.75 metric thread with a 40 mm length under head. It is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces surface reflectivity. The material grade is 12.9, indicating high tensile strength suited for demanding clamping and load-bearing connections. Drive type is internal hex, compatible with standard metric hex keys and socket drivers.

This fastener is used across a wide range of trade and industrial applications including HVAC equipment mounting, pump and motor assembly, structural steel fabrication, and general mechanical maintenance. The M12 x 1.75 thread size and 40 mm under-head length make it a common choice when a fully threaded, high-strength cap screw is required. It conforms to DIN 912 and ISO 898-1 standards, making it appropriate for applications where fastener specification compliance is required.

Key Features

• M12 x 1.75 metric thread, fully threaded along the 40 mm under-head length
• Grade 12.9 alloy steel construction for high tensile and yield strength
• Black oxide finish for mild corrosion resistance and low-glare appearance
• Internal hex drive compatible with standard metric hex keys and socket drivers
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M12 x 1.75 tapped holes in machinery, mechanical assemblies, and fabricated structures where a Grade 12.9 fastener is specified.

Installation Notes

Installation is performed by maintenance technicians, millwrights, pipefitters, or HVAC mechanics using a metric hex key or socket driver sized for M12 socket cap screws. Ensure the receiving threaded hole is clean and correctly tapped to M12 x 1.75 before installation. De-energize and lock out any equipment before fastener replacement or assembly work. Do not substitute a lower-grade fastener in applications that specify Grade 12.9.
