Value Collection 704104PR Set Screw 4-40 Cone Point A2

Product Description

The VALUE COLLECTION 704104PR is a 4-40 UNC cone point set screw manufactured from austenitic stainless steel to Austenitic Grade A2 standards. At 3/16 inches in overall length, this headless fastener is driven by a 0.050-inch hex key and seats against a shaft or bore surface using its hardened cone point to resist rotational and axial movement. It meets ASME/ANSI B18.3 and ASTM F880 dimensional and performance standards. Maintenance technicians, millwrights, and assembly professionals install these screws in precision mechanical assemblies where corrosion resistance and positive point engagement are required.

This set screw is suited for light-duty shaft-to-hub locking applications in environments where stainless steel is specified for corrosion resistance. Typical installations include motor shafts, collars, knobs, and small mechanical assemblies found in HVAC equipment, plumbing components, and general industrial machinery. The cone point geometry concentrates clamping force at a single contact point, making it appropriate for permanent or semi-permanent installations on hardened or soft shaft materials.

Key Features

• Cone point geometry provides concentrated axial holding force on shaft or bore surfaces
• Austenitic Grade A2 stainless steel construction resists corrosion in wet or chemically active environments
• Meets ASME/ANSI B18.3 and ASTM F880 standards for dimensional accuracy and performance
• 0.050-inch hex key drive for installation in tight or recessed access areas
• 4-40 UNC thread for compatibility with standard inch-series tapped holes
• 3/16-inch overall length suits shallow engagement applications

Compatibility

Designed for use in any standard 4-40 UNC tapped through-hole or blind hole requiring a cone point set screw per ASME/ANSI B18.3.

Installation Notes

Installation requires a 0.050-inch hex key torque driver. Ensure the mating tapped hole is clean and free of debris before threading the screw. De-energize and lock out any equipment before servicing shaft-mounted components. Avoid overtightening, as cone point contact can permanently mark or deform soft shaft materials.
