Value Collection 601107PR Set Screw 5-40 X 1 in Cup Point

Product Description

The VALUE COLLECTION 601107PR is a cup point set screw designed for clamping and positioning applications where a headless fastener is required. Manufactured from alloy steel, it provides the strength needed to hold shafts, collars, and similar components firmly in place. The screw features a 5-40 UNC thread with an overall length of 1 inch and is driven with a 1/16 inch hex key. It meets ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional accuracy and material consistency. This type of fastener is installed by machinists, millwrights, and mechanical contractors in light-duty mechanical assemblies.

Cup point set screws are commonly used in shaft collars, pulleys, gears, and knobs where the cup point bites into the mating surface to resist rotation and axial movement. The 5-40 thread size and 1 inch length make this screw suited for small-diameter shafts and precision mechanical components found in instrumentation, light machinery, and electronic assemblies. Minimum order quantity is 10 pieces.

Key Features

• Cup point geometry bites into mating surface for positive grip on shafts and collars
• Alloy steel construction provides strength and wear resistance
• 5-40 UNC thread for use in small-diameter precision applications
• 1/16 inch hex drive compatible with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below surface to avoid interference with moving parts

Compatibility

Designed as a standard-dimension replacement or new-installation set screw for any 5-40 UNC tapped hole application requiring a cup point, headless hex-drive fastener per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 1/16 inch hex key. Always de-energize and lock out any rotating equipment before installing or adjusting set screws. Thread the screw in by hand to avoid cross-threading, then torque to the assembly requirement using an appropriate hex driver. Inspect the mating shaft surface for burrs that could prevent full seating of the cup point.
