Value Collection 704431PR Set Screw 5/16-18 X 1 in Cone Point

Product Description

The VALUE COLLECTION 704431PR is a 5/16-18 x 1-inch cone point set screw manufactured from austenitic Grade A2 stainless steel. Set screws of this type are fully threaded, headless fasteners used to secure a component — such as a collar, gear, pulley, or sprocket — against a shaft by applying direct point pressure. The cone point tip bites into the mating surface for firm, positive retention. Drive is a 5/32-inch hex socket (Allen key). This fastener meets ASME/ANSI B18.3 and ASTM F880 standards, making it suitable for applications where dimensional accuracy and material traceability are required.

Austenitic Grade A2 stainless steel provides good corrosion resistance, making this set screw appropriate for light industrial, marine-adjacent, food-processing-adjacent, and general mechanical applications where carbon steel would be prone to rust or staining. The UNC thread form (5/16-18) is the standard coarse-pitch thread used throughout North American mechanical assemblies. Installers working on HVAC components, pump assemblies, conveyor systems, or similar equipment will find this fastener a practical choice for shaft-to-hub retention tasks.

Key Features

• Cone point tip provides positive shaft engagement and firm holding force
• Austenitic Grade A2 stainless steel for corrosion resistance in demanding environments
• 5/16-18 UNC coarse thread — standard North American thread pitch
• 5/32-inch hex socket drive; compatible with standard Allen key sets
• Meets ASME/ANSI B18.3 and ASTM F880 dimensional and material standards
• Headless design allows flush or sub-flush installation in tapped through-holes

Compatibility

Designed as a standard 5/16-18 UNC cone point set screw for use in any tapped hole or threaded assembly calling for this thread size, length, point type, and stainless steel material grade.

Installation Notes

Installation requires a 5/32-inch hex key or Allen driver. Ensure the receiving hole is properly tapped to 5/16-18 UNC before driving the screw. De-energize and lock out any machinery before servicing shaft-mounted components secured by set screws. Avoid over-torquing, which can deform the cone point or strip the socket; tighten to the fastener manufacturer's recommended torque range for the thread size and material class.
