Value Collection 601538BR Set Screw 1-14 Cup Point Alloy Steel

Product Description

The VALUE COLLECTION 601538BR is a cup point set screw designed for secure, no-protrusion fastening in mechanical assemblies. Threaded 1-14 UNF and measuring 2.5 inches in overall length, this screw is driven with a 9/16-inch hex key and meets the ASME/ANSI B18.3 and ASTM F912 standards. It is manufactured from alloy steel, which provides the hardness and shear strength required for high-load holding applications. The cup point digs into the mating surface to resist rotation and axial movement under vibration or dynamic load. Machinists, maintenance technicians, and industrial assemblers install this type of fastener across a broad range of shaft, collar, and hub applications.

This set screw is suited for use in manufacturing, MRO maintenance, and industrial equipment assembly where a flush or below-surface fastener is required. The fine 1-14 UNF thread pitch allows precise axial positioning and produces a strong clamp load relative to torque applied. Typical applications include locking collars, pulleys, gears, and couplings onto shafts in both light and heavy industrial settings.

Key Features

• Cup point geometry bites into mating surface for positive anti-rotation hold
• 1-14 UNF fine thread for precise positioning and high clamp load
• 2.5 inches overall length accommodates deep or thick hub installations
• Alloy steel construction rated to ASTM F912 for hardness and tensile strength
• 9/16-inch hex drive compatible with standard hex keys and T-handles
• Conforms to ASME/ANSI B18.3 dimensional standard

Compatibility

Designed as a standard ASME/ANSI B18.3 cup point set screw for any application requiring a 1-14 UNF thread and 2.5-inch overall length in alloy steel.

Installation Notes

Installation requires a calibrated 9/16-inch hex key or Allen driver; use of an undersized or worn key risks rounding the socket. Power down and de-energize all rotating equipment before inserting or removing set screws. Ensure the mating shaft is clean and free of burrs before seating the cup point. Consult applicable machinery OEM specifications for recommended tightening procedures on critical shaft-locking applications.
