Value Collection R63263324 Set Screw 1/2-13 X 3/8 in Cup Point

Product Description

The VALUE COLLECTION R63263324 is a 1/2-13 UNC stainless steel set screw with a cup point tip and hex drive socket. Sized at 3/8 inch overall length with a 1/4-inch hex key drive, this fastener is manufactured from 18-8 stainless steel, providing solid corrosion resistance in wet or chemically active environments. Cup point geometry bites into the mating shaft to resist rotation and axial movement without requiring a through-hole. It is a standard choice for shaft collars, pulleys, sprockets, and mechanical assemblies across HVAC, plumbing, and general mechanical trades.

This set screw is suited for residential and commercial mechanical applications where a flush or below-surface fastening point is required. Typical uses include securing rotating components to shafts, locking set collars, and holding sheaves in position. The 1/2-13 UNC thread is a widely used coarse-thread standard, making this screw compatible with tapped holes in common shaft collars and mechanical hardware throughout the trade. Licensed mechanics, millwrights, and general maintenance technicians are the typical installers.

Key Features

• Cup point tip creates a firm bite into shaft material to resist movement under load
• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• 1/2-13 UNC coarse thread for broad compatibility with standard tapped hardware
• 3/8-inch overall length suits compact collar and hub assemblies
• 1/4-inch hex key drive for precise torque application with standard Allen wrenches
• Headless design seats flush or below the surface of the mating component

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for any 1/2-13 UNC tapped set screw application requiring a cup point and 18-8 stainless steel material grade.

Installation Notes

Installation is performed by mechanical or maintenance technicians using a 1/4-inch hex key or Allen wrench. Always de-energize and lock out rotating machinery before servicing shaft-mounted components. Verify the mating tapped hole is clean and free of debris before threading the screw. Avoid over-tightening, which can deform the cup point or damage the shaft surface; apply torque according to the assembly manufacturer's specifications.
