Value Collection 601441BR Set Screw 3/4-10 X 3.5 in Cup Point

Product Description

The VALUE COLLECTION 601441BR is a 3/4-10 UNC cup point set screw manufactured from alloy steel for high-strength clamping and locking applications. At 3.5 inches in overall length and driven by a 3/8-inch hex key, this fastener meets ASME/ANSI B18.3 and ASTM F912 standards. The cup point geometry bites into the mating surface to resist axial and rotational movement, making it a reliable choice in shaft-collar, pulley, and mechanical assembly applications. Machinists, millwrights, and maintenance technicians reach for this style of set screw when positive retention under vibration or load is required.

This set screw is suited for industrial and mechanical assembly environments where a UNC 3/4-10 threaded hole is present. Typical applications include securing collars, sprockets, pulleys, and couplings to shafts. The alloy steel construction handles the clamping torque required for larger-diameter fasteners in this size class without deformation at the drive or point.

Key Features

• Cup point geometry bites into shaft surface to resist rotation and axial movement
• 3/4-10 UNC thread for compatibility with standard coarse-thread tapped holes
• 3/8-inch hex drive for use with standard hex keys and Allen wrenches
• Alloy steel construction provides high hardness and tensile strength
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• 3.5-inch overall length suits deeper collars and extended engagement requirements

Compatibility

Designed for use in any application with a 3/4-10 UNC tapped hole requiring a cup point set screw per ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Installation requires a 3/8-inch hex key or Allen wrench; confirm the mating tapped hole is clean and free of debris before threading. De-energize or lock out any rotating equipment before installing or adjusting set screws on shafts or couplings. Do not exceed the torque capacity of the drive by using extended-handle tools unless the joint design calls for it. Thread engagement should be sufficient to develop full fastener load without bottoming the screw in a blind hole.
