Value Collection 101667BR Set Screw 3/4-10 X 1-1/2 in Cup Point

Product Description

The VALUE COLLECTION 101667BR is a 3/4-10 UNC cup point set screw manufactured from Grade 8 alloy steel. At 1-1/2 inches in overall length, this fastener is driven with a 3/8-inch hex key and seats with a cup point tip that bites into the mating surface to resist rotation and axial movement. Grade 8 alloy steel construction delivers high tensile strength, making this screw appropriate for heavy-duty clamping and locking applications in mechanical assemblies. It conforms to ASME/ANSI B18.3 and ASTM F912 standards. Licensed tradespeople and maintenance mechanics use this type of fastener in shaft-to-hub connections, collars, pulleys, and similar machine components.

This set screw is suited for industrial, commercial, and mechanical service applications where a headless, flush-seating fastener is required. The 3/4-10 UNC thread is a coarse-thread form common in power transmission components, motor mounts, and heavy mechanical assemblies. The cup point geometry is the most widely used set screw tip style, providing reliable grip on both hardened and unhardened shafts. It is sold in minimum order quantities of 10 units.

Key Features

• 3/4-10 UNC coarse thread for secure engagement in standard tapped holes
• Cup point tip grips shaft surfaces and resists loosening under vibration and torque loads
• Grade 8 alloy steel construction provides high proof load and tensile strength
• 3/8-inch hex drive accepts standard hex keys and Allen wrenches
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design allows flush or below-surface installation

Compatibility

Designed as a standard 3/4-10 UNC cup point set screw suitable for use in any tapped hole conforming to ASME/ANSI B18.3 specifications, including shaft collars, hubs, pulleys, gears, and similar mechanical components requiring a headless clamping fastener.

Installation Notes

Installation is performed by licensed mechanics or qualified maintenance personnel using a 3/8-inch hex key or Allen wrench. De-energize and lock out all equipment before installing or removing set screws in rotating assemblies. Verify that the tapped hole is clean and that the thread specification of the mating component matches 3/4-10 UNC before installation. Do not exceed the rated capacity of the mating material, and inspect the cup point and thread condition before reuse.
