Value Collection R63006282 Set Screw 5/16-18 X 1-1/2 in

Product Description

The VALUE COLLECTION R63006282 is a cup point set screw designed for mechanical assemblies where a fastener must apply clamping force without protruding above a surface. The 5/16-18 UNC thread size and 1-1/2 inch body length make it suitable for medium-duty shaft-to-hub, collar, or fixture locking applications. Driven with a square drive tool, the cup point bites into the mating surface to resist rotation and axial movement. Constructed from Grade 18-8 stainless steel, the fastener offers corrosion resistance suitable for wet, humid, or chemically exposed environments. Machinists, millwrights, and mechanical technicians are the primary installers.

This set screw is used in a wide range of industrial and commercial applications including motor shaft collars, shaft couplings, pulleys, sprockets, and adjustable mechanical fixtures. The cup point geometry concentrates clamping load at a defined contact area, providing reliable holding power without requiring a through-hole. It is appropriate for use on steel, aluminum, and other common shaft materials. The minimum order quantity is 5 pieces per order.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard tapped holes
• 1-1/2 inch length under head for extended engagement depth
• Cup point geometry concentrates clamping force to resist shaft rotation and axial movement
• Square drive for high torque application with a square-drive wrench or bit
• Grade 18-8 stainless steel construction provides corrosion resistance in wet or humid environments

Compatibility

Designed as a standard 5/16-18 UNC cup point set screw for use in any tapped hole or threaded collar matching that thread specification.

Installation Notes

Installation is typically performed by machinists or mechanical technicians using a square-drive wrench or bit matched to the drive recess. De-energize and lock out any rotating machinery before installing or adjusting set screws on shafts or couplings. Verify that the tapped hole thread class matches the fastener thread tolerance before final tightening. Do not use impact drivers on stainless steel set screws, as galling of the threads can occur.
