Value Collection 706105PR Set Screw 4-40 X 3/16 in Half Dog A2

Product Description

The VALUE COLLECTION 706105PR is a 4-40 UNC threaded set screw with a half dog point, manufactured from austenitic grade A2 stainless steel. Measuring 3/16 inches in overall length, this fastener is driven by a hex key (0.0500 inch hex key size) and meets ASME/ANSI B18.3 and ASTM F880 standards. Set screws of this type are used to secure components onto shafts or within assemblies without a protruding head. The A2 stainless steel construction provides corrosion resistance suitable for general industrial, mechanical, and light marine applications. Sold in minimum order quantities of 100 pieces per order.

This set screw is suited for light mechanical assemblies where a flush or recessed fastener is required. The half dog point provides positive location and partial engagement into a mating hole or flat on a shaft, making it appropriate for use in collars, shaft couplings, knobs, pulleys, and similar components. It is commonly specified in instrumentation, light machinery, and precision assembly work where a 4-40 thread is the design standard.

Key Features

• Half dog point for positive shaft or bore location and partial engagement
• 4-40 UNC thread for use in fine, light-duty fastening applications
• Austenitic grade A2 stainless steel for corrosion resistance
• Hex drive (0.0500 inch key size) for installation in confined spaces
• Meets ASME/ANSI B18.3 and ASTM F880 fastener standards
• Overall length of 3/16 inches for compact assembly profiles

Compatibility

Designed as a standard 4-40 UNC half dog point set screw for use in any assembly or component specifying a 4-40 threaded headless fastener with a half dog point and hex drive.

Installation Notes

Installation is performed with a 0.0500 inch hex key. Ensure the mating threaded hole is clean and free of debris before driving the screw. Torque the fastener to the assembly specification for 4-40 stainless hardware to avoid galling, which is common with austenitic stainless fasteners. An anti-galling compound is recommended when threading stainless steel into stainless steel.
