Value Collection 601257PR Set Screw 5/16-24 X 1-1/2 in Cup Point

Product Description

The VALUE COLLECTION 601257PR is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies. It features a 5/16-24 UNF thread and measures 1.5 inches in overall length. The cup point digs into the mating surface to resist rotation and axial movement without requiring a through-hole. Manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards, it delivers reliable clamping force in demanding industrial and mechanical applications. Installation requires a 5/32-inch hex key. This screw is suited for machinists, maintenance technicians, and mechanical contractors working on shaft collars, gears, pulleys, and similar components.

Cup point set screws like the 601257PR are commonly used in light to medium-duty shaft-to-hub connections in manufacturing equipment, conveyor systems, and general mechanical assemblies. The 5/16-24 UNF thread provides finer thread engagement compared to UNC equivalents, making it appropriate for applications requiring precise adjustment or reduced vibration loosening. Sold in minimum order quantities of 100 pieces per order, this part is suited for production runs or facilities that maintain bulk fastener inventory.

Key Features

• Cup point geometry bites into the mating shaft surface to resist rotation and axial displacement
• 5/16-24 UNF thread for fine-pitch engagement and precise positional control
• Alloy steel construction meets ASTM F912 material grade requirements
• Conforms to ASME/ANSI B18.3 dimensional standard for hex socket set screws
• 5/32-inch hex drive compatible with standard hex keys and L-wrenches
• 1.5-inch overall length suits deeper shaft engagement applications

Compatibility

Designed as an OEM-style and aftermarket replacement set screw for mechanical assemblies requiring a 5/16-24 UNF cup point fastener conforming to ASME/ANSI B18.3 and ASTM F912 standards.

Installation Notes

Installation is performed with a 5/32-inch hex key or L-wrench. De-energize and lock out any equipment before accessing shaft assemblies. Ensure the mating shaft surface is clean and free of debris before seating the cup point. Follow applicable industry torque guidelines for 5/16-24 set screws and inspect for full thread engagement before returning equipment to service.
