Value Collection 704107PR Set Screw 4-40 X 1/4 in Cone Point Ss A2

Product Description

The VALUE COLLECTION 704107PR is a 4-40 UNC stainless steel set screw with a cone point tip, manufactured to Austenitic Grade A2 material standards. This headless fastener is driven by a 0.050-inch hex key and measures 1/4 inch in overall length. It meets ASME/ANSI B18.3 and ASTM F880 standards, making it suitable for precision fastening applications where corrosion resistance and dimensional consistency are required. Machinists, maintenance technicians, and assembly professionals use cone point set screws to lock components onto shafts or rods by biting directly into the mating surface.

This set screw is suited for light-duty shaft locking, collar positioning, and mechanical assembly applications where a small-diameter, fine-thread fastener is needed. The 4-40 thread size and 1/4-inch length are common in instrumentation, small motor assemblies, and precision mechanical components across industrial and commercial maintenance environments. The cone point geometry concentrates clamping force at a single contact point, providing positive retention on soft or hardened shaft materials.

Key Features

• Thread size 4-40 UNC for precise engagement in fine-thread applications
• Cone point tip concentrates holding force for positive shaft locking
• Austenitic Grade A2 stainless steel resists corrosion in wet or chemical environments
• 0.050-inch hex key drive for compact, recessed installation
• Meets ASME/ANSI B18.3 and ASTM F880 dimensional and material standards
• Overall length of 1/4 inch for low-profile, space-constrained assemblies

Compatibility

Designed as a standard 4-40 UNC cone point set screw for use in any application requiring an ASME/ANSI B18.3 compliant headless fastener in that thread size and length.

Installation Notes

Installation is performed with a 0.050-inch hex key; confirm the mating threaded hole is clean and free of debris before driving. De-energize and lock out any equipment before servicing assemblies that contain set screws on rotating shafts. Do not overtighten, as the cone point can permanently deform soft shaft materials. Follow applicable facility maintenance procedures and torque guidelines for 4-40 stainless fasteners as specified in your engineering documentation.
