Value Collection 42966 Set Screw M12 X 1.75 Cup Point Din 916

Product Description

The VALUE COLLECTION 42966 is a metric cup point set screw designed for secure shaft-to-hub and collar locking applications in industrial and mechanical assemblies. Manufactured from alloy steel to Grade 14.9 (45H), this fastener delivers high tensile strength and reliable holding force under demanding conditions. The cup point geometry bites into the mating surface to resist rotational and axial movement. Driven with a 6 mm hex key, the screw follows DIN 916 standards, ensuring dimensional consistency and interchangeability with other DIN 916-compliant hardware. Each pack contains 10 screws.

This set screw is suited for general mechanical, industrial maintenance, and MRO applications where a metric fastener with a recessed hex drive is required. Typical uses include securing pulleys, gears, collars, and couplings onto shafts. The M12 x 1.75 thread size and 14 mm overall length make it appropriate for medium-duty shaft assemblies found in manufacturing equipment, conveyors, and machine tools. Licensed tradespeople and maintenance technicians working on mechanical power transmission components are the primary installers.

Key Features

• Alloy steel construction, Grade 14.9 (45H) for high tensile and torsional strength
• Cup point tip bites into shaft surface to resist axial and rotational slippage
• DIN 916 standard ensures dimensional interchangeability with compatible metric fasteners
• Hex socket drive accepts a 6 mm hex key for recessed or flush installation
• M12 x 1.75 metric thread with 14 mm overall length suits medium-duty assemblies
• Sold in a pack of 10 screws for job-lot convenience

Compatibility

Designed as a DIN 916-compliant metric cup point set screw for use in any application requiring an M12 x 1.75 threaded socket set screw with a 6 mm hex drive.

Installation Notes

Installation is performed by maintenance technicians or millwrights using a 6 mm hex key or Allen driver. De-energize and lock out all machinery before accessing shaft assemblies. Thread the screw into the pre-tapped hole by hand first to confirm thread engagement, then tighten with the hex key to the torque value specified in the equipment service manual. Avoid over-driving, as the cup point can damage the shaft surface beyond the intended bite depth.
