Value Collection 706430PR Set Screw 5/16-18 X 3/4 in Half Dog

Product Description

The VALUE COLLECTION 706430PR is a half dog point set screw designed for precision fastening applications where a defined contact point is required. Sized at 5/16-18 UNC thread by 3/4 inches overall length, this screw is machined from austenitic Grade A2 stainless steel, offering solid corrosion resistance in wet, chemical, or outdoor service environments. Drive engagement is through a 5/32-inch hex socket. The fastener meets ASME/ANSI B18.3 and ASTM F880 standards, making it a specification-grade component for industrial and mechanical assemblies. Machinists, maintenance mechanics, and MRO technicians are the typical installers.

This set screw fits applications where a half dog point is specified to engage a mating hole or flat on a shaft, collar, or hub assembly. The half dog point provides positive axial location and moderate holding force without requiring a full cone or cup point contact. Common use cases include shaft collars, gear hubs, pulleys, and mechanical couplings in light to medium industrial settings. Grade A2 stainless is suitable for mildly corrosive environments and food-adjacent equipment where carbon steel fasteners are not appropriate.

Key Features

• Half dog point geometry for positive shaft or bore location
• 5/16-18 UNC thread — standard fractional inch coarse thread pitch
• 3/4 inches overall length for medium-depth engagement
• Austenitic Grade A2 stainless steel for corrosion resistance
• 5/32-inch hex socket drive — standard hex key compatible
• Meets ASME/ANSI B18.3 and ASTM F880 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-use set screw for mechanical assemblies requiring a 5/16-18 UNC half dog point fastener in stainless steel.

Installation Notes

Installation is performed by maintenance mechanics or machinists using a calibrated 5/32-inch hex key or T-handle driver. Ensure the mating shaft or component is clean and free of burrs before seating the half dog point. De-energize and lock out any rotating equipment before servicing assemblies that contain set screws. Do not over-torque — confirm torque requirements against the assembly drawing or equipment service manual.
