Value Collection 601523BR Set Screw 1-8x5 in Cup Point

Product Description

The VALUE COLLECTION 601523BR is a cup point set screw designed for secure, flush fastening applications where a protruding head is not acceptable. Manufactured from alloy steel to the ASTM F912 material grade, this fastener meets ASME/ANSI B18.3 dimensional standards. It features a 1-8 UNC thread size, an overall length of 5 inches, and a 9/16-inch hex drive socket. Cup point geometry bites into the mating surface to resist rotation and axial movement under load. Machinists, millwrights, and maintenance technicians install this type of fastener routinely in shaft collars, pulleys, gears, and mechanical assemblies.

This set screw is suited for general industrial and mechanical maintenance applications where a headless, internally driven fastener is required. The 1-8 UNC coarse thread pitch is common in heavy mechanical assemblies and works well in steel, cast iron, and similar base materials. The 5-inch overall length accommodates deeper engagement requirements in thick hubs or collars. Typical use cases include securing rotating components to shafts in industrial machinery, HVAC equipment drives, and pump assemblies.

Key Features

• Cup point tip bites into shaft surface for strong resistance to rotation and axial displacement
• 1-8 UNC coarse thread for reliable engagement in heavy mechanical assemblies
• 5-inch overall length suits deep hub and collar applications
• Alloy steel construction rated to ASTM F912 for high strength and hardness
• 9/16-inch hex socket drive compatible with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 dimensional standards for consistent fit

Compatibility

Designed as an OEM-style replacement or standard stock fastener for mechanical assemblies requiring a 1-8 UNC headless set screw with a cup point and 5-inch overall length.

Installation Notes

Installation is performed by qualified machinists, millwrights, or maintenance technicians using an appropriate 9/16-inch hex key or Allen driver. Always de-energize and lock out equipment before servicing rotating components. Apply consistent torque to seat the cup point firmly against the shaft without stripping the socket. Do not substitute a smaller or worn hex key, as rounding the socket will make removal difficult.
