Value Collection 703431PR Set Screw 5/16-18 X 1 in Flat Point Ss A2

Product Description

The VALUE COLLECTION 703431PR is a 5/16-18 x 1 inch flat point set screw manufactured from austenitic Grade A2 stainless steel. It is driven by a 5/32 inch hex key and conforms to ASME/ANSI B18.3 and ASTM F880 standards. Set screws of this type are headless fasteners used to secure a component — such as a collar, gear, pulley, or sprocket — against a shaft by applying direct clamping force at the point contact. The flat point style distributes load across the bearing surface without marring the shaft, making it well suited for applications where the shaft must remain undamaged and repositionable. Machinists, millwrights, and maintenance technicians are the typical installers.

This set screw is used across a wide range of industrial, mechanical, and trade applications including HVAC equipment assemblies, pump and motor shaft retention, and general mechanical fabrication. The 5/16-18 UNC thread size is a common fractional-inch coarse thread found in standard shaft collars, set collar assemblies, and equipment manufactured to inch-standard specifications. The austenitic stainless steel construction makes it appropriate for installations exposed to moisture, mild chemicals, or environments where corrosion resistance is required.

Key Features

• Flat point tip protects shaft surfaces from marring during tightening
• 5/32 inch hex drive for standard Allen key or hex bit installation
• Austenitic Grade A2 stainless steel provides corrosion resistance in wet or chemically active environments
• 5/16-18 UNC coarse thread for compatibility with standard inch-system collars and hardware
• Conforms to ASME/ANSI B18.3 and ASTM F880 dimensional and material standards
• Overall length measurement of 1 inch provides adequate engagement depth for most standard collar thicknesses

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 5/16-18 UNC flat point set screw with a 5/32 inch hex drive, conforming to ASME/ANSI B18.3 and ASTM F880.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a 5/32 inch hex key or Allen-drive bit. De-energize and lock out all rotating equipment before installing or adjusting set screws. Ensure the shaft and collar bore are clean and free of debris before seating the fastener. Do not overtighten, as excessive torque can deform the flat point or damage the mating shaft surface.
