Value Collection 141031PR Set Screw 8-32 X 1/2 in Half Dog

Product Description

The VALUE COLLECTION 141031PR is an alloy steel set screw with a half dog point, sized 8-32 x 1/2 inches overall length. It is driven by a 5/64 inch hex key and manufactured to ASME/ANSI B18.3 and ASTM F912 standards at Grade 8 material strength. Set screws of this configuration are used to secure components onto shafts or inside housings without a protruding head. The half dog point provides a short cylindrical tip that locates into a mating hole or detent, resisting axial movement under load. Licensed tradespeople and maintenance technicians across mechanical, HVAC, and industrial service work encounter this fastener type routinely.

This set screw is suited for mechanical assemblies where a flush or recessed fastener is required. Common applications include locking collars, pulleys, gears, and shaft-mounted components in HVAC equipment, pumps, and general machinery. The UNC thread standard ensures broad compatibility with standard inch-series tapped holes at the 8-32 thread pitch. Minimum order quantity is 100 pieces, sold as individual units per package.

Key Features

• Half dog point provides positive location into a mating hole or detent for secure axial retention
• Grade 8 alloy steel construction for high tensile and torsional strength
• 5/64 inch hex drive for use with standard hex keys or L-wrenches
• UNC 8-32 thread standard for compatibility with common inch-series tapped holes
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• 1/2 inch overall length suits shallow to medium-depth set screw applications

Compatibility

Designed as a standard-geometry replacement or stock fastener for mechanical assemblies using 8-32 UNC tapped holes requiring a half dog point set screw per ASME/ANSI B18.3.

Installation Notes

Installation is typically performed by mechanical technicians, HVAC service professionals, or millwrights using a 5/64 inch hex key or matching L-wrench. De-energize and lock out all rotating or powered equipment before installing or removing set screws. Ensure the mating tapped hole is clean and free of debris before threading in the fastener. Do not exceed the torque capacity of the 8-32 thread; use a calibrated torque driver when the application requires controlled preload.
