Value Collection 601497BR Set Screw 7/8-14 Cup Point Alloy Steel

Product Description

The VALUE COLLECTION 601497BR is a cup point set screw engineered for secure, flush fastening in mechanical assemblies. Manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards, this fully threaded fastener features a 7/8-14 UNF thread profile and measures 1-1/4 inches in overall length. The cup point geometry bites into mating surfaces to resist rotation and axial movement under load, making it well suited for shaft-collar, gear-hub, and fixture-retention applications. Installation is performed with a 1/2-inch hex key. Machinists, millwrights, and maintenance technicians commonly specify this fastener where a recessed drive and positive point engagement are required.

This set screw is used in shaft collars, shaft-mounted sprockets, pulleys, gears, and similar mechanical components across light industrial and commercial applications. The 7/8-14 UNF thread is a fine-pitch designation appropriate for assemblies where precise axial positioning and vibration resistance are priorities. The cup point seats against the shaft surface without requiring a flat, distributing clamping force over a small circular contact area.

Key Features

• Cup point geometry provides positive grip on round shafts without requiring a machined flat
• 7/8-14 UNF fine-pitch thread for precise positioning and vibration resistance
• Alloy steel construction to ASTM F912 grade for high hardness and tensile strength
• Conforms to ASME/ANSI B18.3 dimensional standards
• 1/2-inch hex drive — installed with a standard hex key or Allen driver
• 1-1/4 inches overall length suits medium shaft-collar depths

Compatibility

Designed as an OEM-style replacement or service fastener for any mechanical assembly requiring a 7/8-14 UNF cup point set screw conforming to ASME/ANSI B18.3 and ASTM F912 standards.

Installation Notes

Installation should be performed by a qualified machinist, millwright, or maintenance technician familiar with threaded fastener procedures. Ensure the mating bore and threads are clean and free of debris before engagement. Use a properly sized 1/2-inch hex key to achieve adequate seating torque; do not use an undersized key, as this risks rounding the drive socket. De-energize and lock out all rotating equipment before installing or removing set screws per applicable LOTO procedures.
