Value Collection 703429PR Set Screw 5/16-18 X 1/2 in Flat Point

Product Description

The VALUE COLLECTION 703429PR is a flat point set screw designed for secure, non-marring clamping and positioning applications in mechanical assemblies. Manufactured from austenitic Grade A2 stainless steel, this fastener delivers strong corrosion resistance suited to wet, outdoor, and chemically exposed environments. The 5/16-18 UNC thread and 1/2-inch overall length make it a common choice in shaft collars, pulleys, and fixture components. Driven by a 5/32-inch hex key, it conforms to ASME/ANSI B18.3 and ASTM F880 standards, ensuring dimensional accuracy and consistent performance in precision-critical installations. Machinists, millwrights, and maintenance technicians routinely specify this size and grade for stainless-compatible assemblies.

This set screw is used in residential and commercial mechanical systems wherever a flush or recessed fastening point is required without protruding hardware. Flat point geometry distributes clamping force across the mating surface, reducing the risk of shaft damage compared to cup or cone point configurations. Typical applications include motor shaft retention, collar locking, and set-position locking in HVAC equipment components, pump assemblies, and general mechanical systems requiring stainless hardware.

Key Features

• 5/16-18 UNC thread with 1/2-inch overall length for precise fit in standard tapped holes
• Flat point geometry minimizes surface damage on mating shafts and seats
• Austenitic Grade A2 stainless steel provides excellent corrosion resistance
• 5/32-inch hex drive for standard Allen key installation
• Meets ASME/ANSI B18.3 and ASTM F880 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard 5/16-18 UNC flat point set screw suitable for any tapped bore or assembly requiring this thread size, drive type, and stainless steel material grade.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a calibrated 5/32-inch hex key. Ensure the mating threaded bore is clean and free of debris before driving the screw. Do not exceed the torque capacity of the stainless steel fastener, as over-torquing Grade A2 material can cause galling. De-energize and lock out any rotating equipment before servicing assemblies that incorporate this fastener.
