Value Collection 141049PR Set Screw 10-24 5/16 in Half Dog Grade 8

Product Description

The VALUE COLLECTION 141049PR is a 10-24 UNC alloy steel set screw with a half dog point, manufactured to Grade 8 strength and conforming to ASME/ANSI B18.3 and ASTM F912 standards. At 5/16 inches in overall length, this screw is driven with a 3/32-inch hex key and provides a positive mechanical stop or locating function where the half dog point engages a mating hole or groove in the workpiece. Grade 8 alloy steel construction delivers the high torsional and tensile strength required for demanding fastening applications. This fastener is typically installed by machinists, millwrights, and maintenance technicians working in industrial or mechanical assembly environments.

Half dog point set screws are widely used in shaft-to-hub connections, collars, couplings, pulleys, and similar mechanical assemblies where the point must seat into a drilled locating hole to prevent axial or rotational movement. The 10-24 thread is a coarse unified national thread, common in light-to-medium duty mechanical components. These screws suit both original equipment assembly and field repair or replacement work across manufacturing, HVAC equipment, and general industrial machinery.

Key Features

• Half dog point for positive engagement with mating locating holes in collars and couplings
• Grade 8 alloy steel construction for high tensile and torsional strength
• 10-24 UNC thread for broad compatibility with standard tapped components
• 3/32-inch hex drive for precise torquing with a standard hex key or Allen wrench
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• 5/16-inch overall length suits shallow hub and collar applications

Compatibility

Designed as a standard replacement or assembly fastener for any 10-24 UNC tapped hole requiring a half dog point set screw per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a 3/32-inch hex key. Always de-energize and lock out equipment before servicing any shaft or rotating assembly. Ensure the mating locating hole is clean and free of burrs before seating the half dog point. Do not exceed the rated drive torque for the fastener size, and inspect threads for damage before installation.
