Value Collection 706343PR Set Screw 10-32 X 1/2 in Half Dog Point

Product Description

The VALUE COLLECTION 706343PR is a 10-32 x 1/2 inch half dog point set screw manufactured from austenitic Grade A2 stainless steel. It is driven with a 3/32 inch hex key and meets ASME/ANSI B18.3 and ASTM F880 standards. Half dog point set screws seat into a matching drilled hole or locating feature on a shaft, providing positive axial and rotational location without relying solely on tip pressure. The stainless steel construction resists corrosion in wet, chemical, or outdoor service environments. This fastener is sold individually but requires a minimum order quantity of 100 pieces, making it suited for production, MRO, or maintenance stocking applications.

This set screw is used in light mechanical assemblies where a shaft or component must be positively located and locked in place. Common applications include shaft collars, pulleys, couplings, and gears across HVAC equipment, pumps, fans, and general mechanical assemblies. The UNF 10-32 thread size is standard in smaller mechanical devices and instrument hardware. The half dog point extends beyond the body end to engage a corresponding hole in the mating part, providing more positive location than a cup or cone point.

Key Features

• Half dog point engages a drilled locating hole for positive shaft positioning
• 10-32 UNF thread provides fine thread engagement in thin or small-diameter bosses
• Austenitic Grade A2 stainless steel resists corrosion and oxidation
• 3/32 inch internal hex drive accepts standard hex keys and L-wrenches
• Meets ASME/ANSI B18.3 and ASTM F880 dimensional and material standards
• 1/2 inch overall length suits medium-depth threaded bosses and collars

Compatibility

Designed as a standard 10-32 UNF half dog point set screw for use in any mechanical assembly requiring ASME/ANSI B18.3 compliant fasteners in that thread size and length.

Installation Notes

Set screws are installed by mechanics and maintenance technicians using a 3/32 inch hex key or L-wrench. Ensure the mating shaft has a properly sized locating hole aligned with the set screw before tightening. De-energize and lock out any rotating equipment before installation or removal. Do not overtighten stainless steel fasteners, as galling can occur — applying an anti-galling lubricant to the threads is a common field practice.
