Value Collection R63232924 Set Screw 3/4-10 X 1 in Cup Point Ss

Product Description

The VALUE COLLECTION R63232924 is a 3/4-10 UNC set screw designed for secure, flush fastening in mechanical assemblies. The cup point configuration bites into the mating surface to resist rotation and axial movement without requiring a through-hole or protruding fastener head. Constructed from Grade 18-8 stainless steel, this fastener resists corrosion in wet, humid, or mildly chemical environments. Drive engagement is achieved with a 3/8-inch hex key. Overall length is 1 inch, and the thread standard is UNC. Machinists, millwrights, and maintenance technicians typically install these in shaft collars, couplings, and similar components.

Cup point set screws see common use in industrial equipment, HVAC component assemblies, motor shaft retention, and general mechanical installations where a permanent or semi-permanent hold-down is needed. The 3/4-10 thread size suits medium-to-large shaft collar applications. Grade 18-8 stainless steel construction makes this fastener appropriate for installations where carbon steel would corrode prematurely, including outdoor mechanical enclosures and wet mechanical rooms. This fastener is sold individually.

Key Features

• 3/4-10 UNC thread for compatibility with standard coarse-thread tapped holes
• Cup point design grips mating surface to prevent loosening under vibration
• Grade 18-8 stainless steel construction resists rust and corrosion
• 3/8-inch hex drive for use with standard Allen wrenches or hex keys
• 1-inch overall length suits a range of collar thicknesses and shaft diameters
• Headless design allows flush or below-surface installation

Compatibility

Designed as a standard 3/4-10 UNC cup point set screw suitable for shaft collars, couplings, pulleys, and mechanical assemblies that accept a coarse-thread headless fastener in this size.

Installation Notes

Installation requires a 3/8-inch hex key or Allen wrench; verify the receiving tapped hole is clean and free of debris before threading. Power down and de-energize any rotating equipment before servicing fasteners on shafts or couplings. Do not overtighten beyond the torque capacity of the 18-8 alloy, and confirm the cup point seats fully against the shaft surface to achieve proper holding force. Follow applicable machinery safety standards and facility lockout/tagout procedures during installation.
