Value Collection 601248PR Set Screw 5/16-18 X 2-3/4 in

Product Description

The VALUE COLLECTION 601248PR is a headless cup point set screw designed for secure fastening in mechanical assemblies where a flush or recessed installation is required. Made from alloy steel, this fastener offers solid holding strength for shaft-to-hub connections, collars, and similar applications. It measures 2-3/4 inches in overall length with a 5/16-18 UNC thread and is driven by a 5/32-inch hex key. The cup point geometry bites into the mating surface to resist rotation and axial movement without requiring a protruding head. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards.

Cup point set screws like the 601248PR are common in industrial and mechanical maintenance work. Typical applications include securing pulleys, sprockets, gears, and shaft collars to rotating shafts. They are installed wherever a low-profile fastener is needed inside a threaded bore. This part is sold individually but requires a minimum order of 10 units, making it suitable for shop stock or field kit replenishment for maintenance technicians and millwrights.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard tapped bores
• 2-3/4-inch overall length suits deeper engagement applications
• Cup point tip bites into shaft surface to resist axial and rotational slip
• Alloy steel construction provides high tensile and torsional strength
• 5/32-inch hex drive accepts standard hex keys and L-wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 5/16-18 UNC headless cup point set screw with a 5/32-inch hex drive and 2-3/4-inch overall length.

Installation Notes

Installation is typically performed by maintenance technicians or millwrights using a 5/32-inch hex key or Allen driver. De-energize and lock out the equipment before servicing any shaft or rotating assembly. Thread the set screw into the tapped bore by hand before applying the hex key to avoid cross-threading. Tighten to contact with the shaft surface — do not over-drive, as cup points can deform the shaft if excessive force is applied.
