Value Collection 703430PR Set Screw 5/16-18 X 3/4 in Flat Point

Product Description

The VALUE COLLECTION 703430PR is a 5/16-18 x 3/4 inch flat point set screw machined from austenitic Grade A2 stainless steel. It drives with a 5/32 inch hex key and is manufactured to ASME/ANSI B18.3 and ASTM F880 standards. The flat point style distributes clamping force across a surface without marring or deforming the workpiece, making it the right choice where point contact damage is a concern. This fastener suits machinists, pipefitters, millwrights, and maintenance technicians working with collars, hubs, and shaft-mounted components that require a corrosion-resistant hold.

This set screw is suited for applications where stainless steel is required for corrosion resistance or cleanliness compliance. Typical install scenarios include shaft collars, set-collar assemblies, valve stems, and mechanical drive components in HVAC, plumbing, and light industrial environments. The UNC thread form is the standard for inch-series threaded holes in machinery and equipment manufactured to North American specifications. Minimum order quantity is 10 pieces; each package contains 1 piece.

Key Features

• Flat point eliminates workpiece marring and distributes load evenly across the bearing surface
• Austenitic Grade A2 stainless steel provides corrosion resistance in wet or chemical-exposed environments
• 5/32 inch hex drive compatible with standard L-keys and T-handle hex drivers
• 5/16-18 UNC thread is a common North American inch-series standard for wide tooling compatibility
• Manufactured to ASME/ANSI B18.3 and ASTM F880 for dimensional and mechanical consistency

Compatibility

Designed as a standard-dimension inch-series set screw for use in any 5/16-18 UNC threaded hole requiring a flat point and stainless steel construction.

Installation Notes

Set screws of this type are installed by machinists, millwrights, or maintenance technicians using a 5/32 inch hex key. Always ensure the mating threaded hole is clean and free of debris before installation. De-energize and lock out any rotating or pressurized equipment before servicing shaft-mounted components. Do not exceed the torque range appropriate for Grade A2 stainless fasteners in this thread size, as over-torquing can gall stainless threads.
