Value Collection 601453BR Set Screw 3/4-16 X 3/4 in Cup Point

Product Description

The VALUE COLLECTION 601453BR is a cup point set screw designed for secure, no-protrusion fastening in shafts, collars, and mechanical assemblies. Manufactured from alloy steel to ASTM F912 material grade, this fastener meets ASME/ANSI B18.3 dimensional standards. It features a 3/4-16 UNF thread size, a 3/4-inch overall length, and a 3/8-inch hex key drive. The cup point bites into the mating surface to resist rotation and axial movement without the need for a nut. Machinists, millwrights, and maintenance technicians install this screw where a flush or recessed fastener is required in power transmission and mechanical positioning applications.

This set screw is suited for use in shaft-to-hub connections, set collar assemblies, and mechanical stops across a range of industrial and commercial equipment. The UNF thread form provides fine thread engagement, making it appropriate for applications requiring precise depth adjustment or higher thread strength in thinner materials. It is sold in a minimum order quantity of 10 units, with a package quantity of 1 per unit.

Key Features

• Cup point geometry bites into shaft surface to resist torque and axial shift
• Alloy steel construction rated to ASTM F912 material grade for high strength
• 3/4-16 UNF thread for fine-pitch engagement and precise depth control
• 3/8-inch hex key drive compatible with standard hex wrenches and Allen keys
• Meets ASME/ANSI B18.3 dimensional standard for consistent fitment
• Headless design sits flush or below the surface, eliminating snag points

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any mechanical assembly requiring a 3/4-16 UNF cup point set screw conforming to ASME/ANSI B18.3.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated 3/8-inch hex key or Allen wrench. Disengage and lock out power to any rotating equipment before installing or adjusting set screws. Ensure the mating shaft is clean and free of burrs before driving the screw to full seating depth. Do not exceed the design torque rating of the assembly; overtightening alloy steel set screws can damage soft shafts or strip the hex socket.
