Value Collection 111189PR Set Screw 10-24 X 3/4 in Grade 8

Product Description

The VALUE COLLECTION 111189PR is a 10-24 x 3/4 inch knurled cup point set screw manufactured from Grade 8 alloy steel. Set screws of this type are headless fasteners used to secure a component — such as a collar, gear, or pulley — to a shaft by applying direct pressure through the threaded body. The knurled cup point bites into the mating surface for positive holding force while resisting loosening under vibration. The 3/32 inch hex drive accepts a standard hex key. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards. It is installed by maintenance technicians, millwrights, and mechanical contractors in a wide range of industrial and mechanical assemblies.

This set screw is suited for shaft-to-hub clamping applications in mechanical power transmission, HVAC equipment assemblies, pump drives, fan hubs, and similar rotating or fixed mechanical connections. The knurled cup point design is appropriate where moderate indentation of the shaft surface is acceptable and where vibration resistance is a priority. The UNC thread form and fractional inch sizing make this compatible with standard inch-series tapped holes commonly found in domestic mechanical equipment and assemblies. This part is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• Knurled cup point provides strong holding force and vibration resistance
• Grade 8 alloy steel construction for high tensile and torsional strength
• 3/32 inch hex drive compatible with standard hex keys and L-wrenches
• UNC thread standard for compatibility with inch-series tapped holes
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard inch-series set screw for use in any 10-24 UNC tapped hole requiring a knurled cup point fastener with a 3/4 inch overall length.

Installation Notes

Installation requires a 3/32 inch hex key or Allen wrench. Power down and de-energize all rotating equipment before installing or adjusting set screws. Ensure the mating shaft and tapped hole are clean and free of debris before threading. Do not exceed the torque rating of the tapped material when seating the screw against the shaft.
