Value Collection 706423PR Set Screw 5/16-18 Half Dog Point Ss A2

Product Description

The VALUE COLLECTION 706423PR is a half dog point set screw designed for mechanical assemblies where a partial cylindrical point is needed to locate or hold a shaft without fully penetrating or damaging it. Sized at 5/16-18 UNC thread with an overall length of 5/16 inches, this fastener is driven with a 5/32-inch hex key. It is manufactured from austenitic Grade A2 stainless steel, providing corrosion resistance suitable for wet, outdoor, or chemically exposed environments. This screw meets ASME/ANSI B18.3 and ASTM F880 standards. Licensed machinists, maintenance technicians, and industrial mechanics are the primary installers.

The 706423PR is appropriate for use in shaft collars, pulleys, gears, and similar mechanical components where a half dog point is specified to engage a pre-drilled hole or flat on the mating part. The half dog point seats partially into a dimple or hole on the shaft, providing positive axial location while minimizing shaft surface damage. It is well suited for light industrial, HVAC, and general mechanical maintenance applications where stainless fasteners are specified for corrosion resistance.

Key Features

• Half dog point geometry for positive shaft location in pre-drilled or dimpled surfaces
• 5/16-18 UNC thread for broad compatibility with standard tapped holes
• 5/32-inch hex socket drive for use with standard Allen or hex key wrenches
• Austenitic Grade A2 stainless steel construction for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F880 fastener standards

Compatibility

Designed as an OEM-style or replacement set screw for any assembly specifying a 5/16-18 UNC half dog point set screw with a 5/32-inch hex drive and overall length of 5/16 inches.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/32-inch hex key or Allen wrench. Ensure the mating shaft has a properly sized and positioned dimple or drilled hole to accept the dog point before tightening. De-energize and lock out any machinery before servicing components containing set screws. Do not overtighten, as excessive torque can deform the socket or damage the mating shaft.
