Value Collection 141019PR Set Screw 8-32 Half Dog Point

Product Description

The VALUE COLLECTION 141019PR is an 8-32 x 1/4 inch half dog point set screw manufactured from Grade 8 alloy steel. Set screws of this type are headless fasteners used to secure a component — such as a collar, pulley, gear, or knob — against a shaft by applying axial clamping force through thread engagement alone. The half dog point provides a short cylindrical tip that seats into a mating hole or detent on the shaft, resisting rotation and axial movement without the need for a standard fastener head. Driven with a 5/64 inch hex key, this screw conforms to ASME/ANSI B18.3 and ASTM F912 standards. It is sized for applications requiring precise, low-profile clamping in tight assemblies.

This set screw is suited for use in light industrial, mechanical, and electromechanical assemblies where a half dog point is specified for positive shaft location. Typical applications include securing shaft collars, encoder wheels, small pulleys, and adjustment mechanisms in equipment where the set point must be repeatable and the mating shaft has a drilled detent. It is ordered in multiples of 100 units, making it appropriate for production runs or maintenance stock replenishment rather than single-unit service calls.

Key Features

• Half dog point tip seats into a drilled detent on the mating shaft for positive, repeatable location
• Grade 8 alloy steel construction provides high tensile and torsional strength relative to screw size
• 8-32 UNC thread for standard compatibility with tapped holes in common mechanical assemblies
• 5/64 inch hex drive allows installation with a standard hex key or Allen wrench in confined spaces
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design allows the fastener to sit fully flush or below the surface of the workpiece

Compatibility

Designed as a standard 8-32 UNC half dog point set screw per ASME/ANSI B18.3 and ASTM F912, suitable for any tapped 8-32 hole requiring a half dog point fastener in mechanical or electromechanical assemblies.

Installation Notes

Installation is performed with a 5/64 inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Confirm the mating shaft has a properly drilled detent sized for the half dog point before installation. De-energize and lock out any equipment before servicing assemblies that contain these fasteners. Thread engagement should span the full tapped depth of the receiving hole to ensure adequate holding force.
