Value Collection R63263884 Set Screw 5/8-11 X 1/2 in Cup Point

Product Description

The VALUE COLLECTION R63263884 is a cup point set screw designed for mechanical fastening applications where a secure, non-projecting hold is required. Manufactured from 18-8 stainless steel, this fastener resists corrosion and light chemical exposure, making it a reliable choice in demanding environments. The 5/8-11 UNC thread designation indicates a coarse-thread profile with 11 threads per inch, sized for 5/8-inch threaded bores. At 1/2 inch in overall length, it is well suited for compact assemblies. Drive is via a 5/16-inch hex key. This screw is used by machinists, millwrights, and maintenance technicians across industrial and mechanical settings.

This set screw is commonly used to secure collars, pulleys, gears, sprockets, and similar components onto shafts without a projecting head. The cup point bites into the shaft surface to resist rotational and axial movement. Typical applications include general manufacturing equipment, conveyor systems, and mechanical assemblies where a flush or recessed fastener profile is required. It is sold individually with a minimum order quantity of one.

Key Features

• Cup point geometry bites into shaft surface to resist slipping under load
• 18-8 stainless steel construction resists corrosion and oxidation
• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes
• 1/2-inch overall length fits compact collar and hub assemblies
• 5/16-inch hex drive accepts standard hex keys and Allen-style wrenches
• Sold as individual unit with no minimum quantity requirement beyond one piece

Compatibility

Designed as a standard UNC coarse-thread set screw for use in any 5/8-11 tapped bore requiring a cup point, non-projecting fastener in corrosion-resistant stainless steel.

Installation Notes

Set screws of this type are installed by machinists and maintenance technicians using a 5/16-inch hex key. Ensure the mating bore is clean and free of debris before threading the screw in by hand to confirm proper thread engagement. Tighten to the assembler's standard procedure for stainless steel fasteners, taking care not to overtighten, as 18-8 stainless is susceptible to galling. De-energize or lock out any rotating equipment fully before servicing components secured by this fastener.
