Value Collection 703371PR Set Screw 1/4-20 X 1/2 in Flat Point

Product Description

The VALUE COLLECTION 703371PR is a 1/4-20 UNC flat point set screw used to lock or position components on shafts, housings, or assemblies without protruding above the surface. Manufactured from Austenitic Grade A2 stainless steel, this fastener resists corrosion in wet, chemical, or outdoor environments where carbon steel hardware is not appropriate. It measures 1/2 inch in overall length and is driven with a 1/8 inch hex key. Compliance with ASME/ANSI B18.3 and ASTM F880 confirms dimensional accuracy and mechanical performance to recognized industry standards. Maintenance technicians, millwrights, and general contractors commonly install this type of hardware during equipment assembly and repair.

Flat point set screws are suited for applications where the mating surface must not be marred or where the screw bears against a flat-ground shaft. Typical uses include securing collars, sprockets, pulleys, and knobs on shafts in light-to-medium duty mechanical assemblies. The stainless steel construction makes this screw a practical choice for HVAC equipment enclosures, plumbing trim hardware, pool equipment fittings, and marine-adjacent environments where moisture exposure is a concern. The 1/4-20 UNC thread is one of the most common inch-series thread forms, making this screw broadly compatible with standard tapped holes across a wide range of manufactured equipment.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard inch-series tapped holes
• Flat point profile prevents shaft marring and suits flush-bearing applications
• Austenitic Grade A2 stainless steel provides corrosion resistance in wet and chemical environments
• 1/8 inch hex drive for use with standard hex keys and L-wrenches
• Meets ASME/ANSI B18.3 and ASTM F880 dimensional and performance standards
• Headless profile sits fully below or flush with the mating surface

Compatibility

Designed as an OEM-style replacement or general-use fastener for any assembly requiring a 1/4-20 UNC flat point set screw with a 1/8 inch hex drive.

Installation Notes

Set screws of this type are installed by maintenance technicians and millwrights using a 1/8 inch hex key or L-wrench. Ensure the tapped hole is clean and free of debris before threading the screw. Do not exceed the torque range appropriate for 1/4-20 stainless steel fasteners, as A2 stainless is subject to galling if over-torqued without lubrication. Applying a small amount of anti-seize compound to the threads is a common practice when installing stainless fasteners into stainless or aluminum tapped holes.
