Value Collection R63266449 Set Screw 10-24 X 0.25 in Cup Point

Product Description

The VALUE COLLECTION R63266449 is a 10-24 UNC set screw designed to lock shafts, collars, pulleys, and similar components without protruding above the mating surface. The cup point configuration bites into the mating material to provide firm holding force under rotational and axial loads. Constructed from 18-8 stainless steel, this fastener resists corrosion in wet or chemically active environments. It measures 0.25 inches in overall length and is driven with a 0.09375-inch (3/32 inches) hex key. These screws are a standard choice for mechanical assemblies in HVAC equipment, pump housings, and light industrial fixtures where a flush or recessed fastener is required.

This set screw is suited for use in residential and light commercial mechanical assemblies. Typical applications include securing set collars to shafts on blower wheels, motor couplings, and valve stems. The 10-24 UNC thread is one of the most common thread sizes found in HVAC and general mechanical equipment, making this screw a practical stock item for service vans and shop inventories. The stainless steel construction makes it appropriate for outdoor, damp, or mildly corrosive environments where carbon steel fasteners would degrade prematurely.

Key Features

• Cup point geometry grips the mating shaft surface to resist rotation and axial movement
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor service conditions
• 10-24 UNC thread is a widely standardized size compatible with common taps and thread gauges
• 0.25-inch overall length suits shallow boss and collar applications
• 3/32-inch hex drive works with standard hex keys and L-wrenches found in most trade toolkits
• Headless design sits flush or below the surface, eliminating snag points in rotating assemblies

Compatibility

Designed as a standard 10-24 UNC replacement or stock set screw for use in any mechanical assembly requiring a cup-point, headless fastener in this thread size and length.

Installation Notes

Installation requires a 3/32-inch hex key or Allen wrench; ensure the key is fully seated before applying torque to avoid rounding the socket. De-energize and lock out any rotating equipment before accessing the fastener. Do not overtighten into soft materials such as aluminum shafting, as the cup point can permanently deform the substrate. Stainless fasteners are susceptible to galling on stainless mating threads; apply an appropriate anti-seize compound if both mating parts are stainless steel.
