Value Collection R63260262 Set Screw 4-40 X 5/8 in Cup Point

Product Description

The VALUE COLLECTION R63260262 is a 4-40 UNC threaded cup point set screw manufactured from 18-8 stainless steel. At 5/8 inches in overall length, it is driven with a 0.050-inch hex key and seats with a cup point that bites into the mating shaft to resist rotation and axial movement. The 18-8 stainless steel construction provides corrosion resistance suitable for indoor and light outdoor mechanical assemblies. This screw is sold in a package quantity of one unit with a minimum order quantity of 100 pieces, making it appropriate for production or maintenance applications requiring consistent stock of a specific fastener.

Cup point set screws in this size range are widely used in mechanical and electromechanical assemblies to secure collars, pulleys, knobs, gears, and similar components to shafts. The 4-40 thread is common in light-duty instrument, HVAC control, and small motor applications. The stainless steel grade makes this fastener a practical choice where mild corrosion resistance is needed without the cost of higher-alloy materials. Trades such as HVAC technicians, electricians, and mechanical maintenance professionals frequently stock this size for field and shop repairs.

Key Features

• 4-40 UNC thread standard for compatibility with fine-threaded light-duty assemblies
• Cup point geometry bites into shaft surface to resist rotation and axial displacement
• 18-8 stainless steel construction for corrosion resistance in moderate environments
• 0.050-inch hex key drive for installation in confined or recessed locations
• 5/8-inch overall length suits collars and hubs with adequate wall depth

Compatibility

Designed as a standard 4-40 UNC cup point set screw suitable for use in any threaded assembly or tapped hole conforming to 4-40 UNC thread specifications.

Installation Notes

Installation requires a 0.050-inch hex key. Ensure the mating threaded hole is clean and free of debris before driving the screw. Apply only enough torque to seat the cup point firmly against the shaft without stripping the small thread. Stainless steel fasteners are susceptible to galling — use a thread-lubricating compound appropriate for stainless if repeated removal is anticipated.
