Value Collection 601369PR Cup Point Set Screw 9/16-12

Product Description

The VALUE COLLECTION 601369PR is a cup point set screw designed for mechanical assemblies where a threaded fastener must apply concentrated clamping force against a shaft or mating surface. Manufactured from alloy steel to ASTM F912 and dimensioned to ASME/ANSI B18.3, this screw features a 9/16-12 UNC thread, a 5/8 inch overall length, and a 1/4 inch internal hex drive. The cup point geometry bites into the mating surface to resist rotation and axial movement. Machinists, millwrights, and maintenance mechanics are the primary installers of this fastener type.

This set screw is appropriate for use in shaft collars, shaft couplings, pulleys, gears, sprockets, and similar rotary or linear mechanical components across light industrial, commercial, and OEM production environments. The UNC thread form is the standard coarse-pitch series used throughout North American mechanical assemblies. The 9/16-12 thread diameter is suitable for medium-to-heavy duty holding applications where fine-thread set screws would be undersized.

Key Features

• Cup point geometry provides concentrated contact force to resist shaft movement
• Alloy steel construction for high tensile and torsional strength
• Meets ASTM F912 material and mechanical property requirements
• Dimensioned to ASME/ANSI B18.3 for standardized fit and interchangeability
• 1/4 inch internal hex drive accepts standard hex keys and hex-socket tooling
• UNC (9/16-12) coarse thread for broad compatibility with standard tapped holes

Compatibility

Designed as a standard ASME/ANSI B18.3 cup point set screw for any 9/16-12 UNC tapped hole application requiring ASTM F912 alloy steel fasteners.

Installation Notes

Set screws of this type are installed by machinists or maintenance mechanics using a 1/4 inch hex key or socket driver. Ensure the mating hole is clean and correctly tapped to 9/16-12 UNC before installation. Do not exceed the recommended seating torque for the drive size, as overdriving can strip the hex socket or damage the mating surface. Consult applicable machinery or equipment manufacturer specifications for torque and preload requirements.
