Value Collection 101575PR Set Screw 1/2-13 X 1 in Cup Point

Product Description

The VALUE COLLECTION 101575PR is a cup point set screw designed for industrial and mechanical fastening applications. It features a 1/2-13 UNC thread with an overall length of 1 inch and is driven by a 1/4 inch hex key. Manufactured from Grade 8 alloy steel, this set screw meets ASME/ANSI B18.3 and ASTM F912 standards. The cup point geometry bites into the mating shaft or surface to resist rotation and axial movement under load. Machinists, maintenance technicians, and assembly professionals install this type of fastener when securing collars, pulleys, gears, and similar components to shafting.

This set screw is suited for heavy-duty industrial and mechanical assemblies where a reliable, non-projecting fastener is required. The cup point is the most common point style for general-purpose shaft locking, making it appropriate for use in conveyor systems, machine tools, pumps, and power transmission equipment. Sold individually, with a minimum order quantity of 100 pieces.

Key Features

• 1/2-13 UNC thread for compatibility with standard inch-series tapped holes
• 1 inch overall length provides deep engagement in the threaded bore
• Cup point geometry grips shaft surface to resist rotation and axial movement
• Grade 8 alloy steel construction for high tensile and torsional strength
• 1/4 inch hex drive accepts standard hex keys and hex-bit sockets
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as an OEM-style replacement or production fastener for any application requiring a 1/2-13 UNC cup point set screw with a 1 inch overall length and 1/4 inch hex drive.

Installation Notes

Installation is performed with a 1/4 inch hex key or hex-bit driver. Ensure the tapped hole is clean and free of debris before threading the set screw in. Apply the appropriate preload torque per the assembly specification and relevant industry standards. Never use the set screw to replace a fastener with a different point type, thread size, or material grade without verifying equivalency.
