The VALUE COLLECTION 88547526 is a cup point set screw designed for secure shaft-to-hub and collar locking applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile and torsional strength suitable for demanding industrial and mechanical service environments. The 1/2-13 UNC thread and 3/4-inch overall length make it a standard choice for medium-duty clamping tasks. A 1/4-inch hex drive socket is required for installation. Each package contains 13 screws, supporting small-batch repair work and maintenance stock.
This set screw is commonly used by millwrights, maintenance mechanics, and industrial service technicians working on pulleys, sprockets, shaft collars, couplings, and similar rotating equipment. The cup point geometry bites into the shaft surface to create a firm mechanical lock, making it well suited for static or low-vibration applications where a positive bite on the mating shaft is required.
Designed as a standard replacement or stock fastener for any mechanical assembly requiring a 1/2-13 UNC cup point set screw in Grade 8 alloy steel.
Installation is typically performed by a qualified mechanic or millwright using a 1/4-inch hex key or Allen wrench. Ensure the shaft and collar bore are clean and free of debris before threading the screw. De-energize and lock out all connected equipment before working on rotating assemblies per applicable LOTO procedures. Do not exceed the rated torque range for Grade 8 fasteners of this thread size as specified by the equipment manufacturer.
