Value Collection 101111PR Set Screw 5-40 X 3/16 in Cup Point

Product Description

The VALUE COLLECTION 101111PR is a cup point set screw sized 5-40 UNC by 3/16 inches overall length, manufactured from Grade 8 alloy steel. It is driven by a 1/16 inch hex key and seats with a cup point that bites into the mating shaft to resist rotational and axial movement. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards. It is used by machinists, millwrights, and maintenance technicians to secure collars, pulleys, gears, and similar components onto shafts without a protruding head, keeping the assembly flush and snag-free.

The 101111PR is suited for light-duty mechanical assemblies where a compact, headless fastener is required. Typical applications include shaft collar retention, set collar locking, and inline component positioning on small-diameter shafts in industrial equipment, HVAC drive assemblies, and general mechanical systems. The 5-40 thread size targets smaller shaft diameters where space is limited. Minimum order quantity is 100 pieces per order.

Key Features

• Cup point geometry grips mating shaft surface to resist rotation and axial shift
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 1/16 inch hex drive for standard hex key installation in tight spaces
• 5-40 UNC thread for precise engagement on small-diameter shaft components
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design keeps installed profile flush with the surrounding surface

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 5-40 UNC cup point set screw with a 1/16 inch hex drive.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 1/16 inch hex key or Allen driver. Ensure the mating shaft and threaded hole are clean and free of debris before installation. De-energize and lock out any equipment before servicing components that incorporate set screws. Do not exceed rated torque for the thread size and grade; consult published fastener torque tables for 5-40 Grade 8 alloy steel.
