Value Collection 601191PR Set Screw 10-32 X 2-1/2 in Cup Point

Product Description

The VALUE COLLECTION 601191PR is a Grade 8 alloy steel set screw designed for high-strength fastening applications where a flush or recessed hold is required. Measuring 10-32 UNF thread by 2-1/2 inches in overall length, this screw features a cup point tip that bites into mating surfaces to resist rotation and axial movement. A 3/32-inch hex drive accepts a standard hex key for installation. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, it is suited for precision assemblies, mechanical collars, shafts, and similar industrial or trade applications.

This set screw is appropriate for use wherever a headless, flush-seated fastener is needed, such as securing shaft collars, pulleys, gears, or mechanical linkages in HVAC equipment, pump assemblies, and general mechanical systems. The cup point profile provides reliable grip on both hardened and soft metal shafts. It is typically installed by maintenance technicians, millwrights, or HVAC/mechanical service professionals working on rotating or assembled components.

Key Features

• Grade 8 alloy steel construction for high tensile and proof load strength
• Cup point tip grips shaft or mating surface to prevent slippage
• 10-32 UNF thread for precise, fine-pitch engagement
• 3/32-inch hex drive compatible with standard hex keys and Allen wrenches
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• 2-1/2-inch overall length accommodates deeper shaft engagement or thicker collars

Compatibility

Designed as an OEM-style or replacement set screw for mechanical assemblies requiring a 10-32 UNF, headless cup-point fastener in Grade 8 alloy steel.

Installation Notes

Installation is performed using a 3/32-inch hex key torqued to the appropriate value for the mating assembly per the equipment manufacturer's specifications. Ensure the mating shaft or bore surface is clean and free of debris before seating the cup point. Confirm the thread engagement is complete and the cup point is properly positioned before applying load. Follow applicable ASME or equipment-specific fastener guidelines when servicing rotating assemblies.
