Value Collection R63266960 Set Screw 5/16-18 X 1-1/2 in

Product Description

The VALUE COLLECTION R63266960 is a cup point set screw designed for secure fastening applications in mechanical assemblies. Manufactured from Grade 18-8 stainless steel, this fastener offers solid corrosion resistance suitable for general industrial and trade use. The screw features a 5/16-18 UNC thread with an overall length of 1-1/2 inches and is driven by a 3/32-inch hex key. Cup point set screws are used to lock components such as collars, pulleys, and gears onto shafts, creating a positive bite into the mating surface. Installation requires a standard hex key driver.

This set screw is suited for use in HVAC equipment, plumbing assemblies, electrical panel components, and general mechanical systems where shaft-to-hub locking is required. The 5/16-18 UNC thread size is a common standard in residential and light commercial trade applications. Grade 18-8 stainless steel construction makes it appropriate for environments with moderate moisture exposure. This fastener is sold individually per package with a minimum order quantity of 100 pieces.

Key Features

• Cup point geometry bites into shaft surface for positive locking without additional hardware
• Grade 18-8 stainless steel construction provides corrosion resistance in moderate-exposure environments
• 5/16-18 UNC thread standard ensures broad compatibility with standard tapped holes
• 3/32-inch hex drive allows use with common hex key sets found in most trade toolkits
• Overall length of 1-1/2 inches suits deeper engagement requirements in collars and hubs

Compatibility

Designed as a standard UNC-thread cup point set screw for use in mechanical assemblies requiring 5/16-18 threaded fastener positions with cup point engagement.

Installation Notes

Set screws are installed by licensed mechanics, HVAC technicians, and maintenance professionals using a properly sized hex key — in this case, 3/32 inch. Always de-energize and lock out equipment before accessing rotating components such as pulleys, couplings, or fan hubs. Do not overtighten, as excessive torque can strip threads or damage the mating shaft surface. Confirm thread engagement before applying final seating force.
