Value Collection 706107PR Set Screw 4-40 X 1/4 in Half Dog Point

Product Description

The VALUE COLLECTION 706107PR is a 4-40 UNC stainless steel set screw with a half dog point, designed for precision fastening applications where a protruding locating point is needed to engage a mating hole or slot. Manufactured from Austenitic Grade A2 stainless steel, this screw offers solid corrosion resistance for use in wet, chemical, or outdoor environments. It measures 1/4 inch in overall length and is driven with a 0.050-inch hex key. The fastener meets ASME/ANSI B18.3 and ASTM F880 standards, making it a reliable choice for industrial, mechanical, and instrumentation assembly work.

This set screw is suited for light-duty holding and positioning applications typical in small mechanical assemblies, instrument panels, and equipment where a 4-40 threaded socket is specified. The half dog point provides a short cylindrical nose that locates into a drilled hole on a shaft or mating component, resisting axial movement without marring shaft surfaces as aggressively as a cup point. Machinists, mechanical assemblers, and maintenance technicians are the primary installers of this fastener type.

Key Features

• 4-40 UNC thread size for compatibility with standard 4-40 tapped holes
• Half dog point geometry for positive shaft or component location
• Austenitic Grade A2 stainless steel construction for corrosion resistance
• 0.050-inch hex drive for precise torque application with standard hex keys
• Meets ASME/ANSI B18.3 and ASTM F880 fastener standards
• 1/4 inch overall length suitable for thin hubs and shallow socket applications

Compatibility

Designed as a standard replacement or production fastener for any assembly specifying a 4-40 UNC half dog point set screw with a 0.050-inch hex drive and 1/4 inch overall length per ASME/ANSI B18.3.

Installation Notes

Install using a calibrated 0.050-inch hex key; avoid using worn or undersized keys that can strip the drive socket. Ensure the mating component has a properly sized dog point receiver hole to allow the half dog point to seat fully. De-energize and lock out any equipment before accessing the assembly. Apply thread-locking compound only if specified by the equipment manufacturer, as removal of stainless fasteners from stainless tapped holes without lubrication can result in galling.
