Value Collection 704469PR Set Screw 3/8-16 X 1/2 in Cone Point

Product Description

The VALUE COLLECTION 704469PR is a cone point set screw designed for secure, positive locking in mechanical assemblies where the point must seat into a mating surface or indent a shaft. Manufactured from austenitic Grade A2 stainless steel, this fastener provides good corrosion resistance in general industrial and light marine environments. It features a 3/8-16 UNC thread and measures 1/2 inch in overall length, driven by a 3/16-inch hex key. It conforms to ASME/ANSI B18.3 and ASTM F880 standards. Machinists, maintenance technicians, and assembly professionals install this type of fastener in collars, pulleys, gears, and shaft-mounted components.

This cone point set screw is suited for applications where a positive, non-slip hold on a shaft or similar round stock is required. The cone point geometry bites into the mating surface, resisting rotation and axial movement under load. Typical use cases include motor shaft collars, conveyor components, and rotating assemblies in light industrial, HVAC equipment, and general mechanical maintenance settings. The stainless steel construction makes it appropriate for environments with moisture exposure or mild chemical contact.

Key Features

• Cone point geometry seats into shaft material for positive locking and axial retention
• Austenitic Grade A2 stainless steel construction for corrosion resistance
• 3/8-16 UNC thread form for broad compatibility with standard tapped holes
• 3/16-inch hex drive for use with standard hex keys or Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F880 fastener standards
• 1/2-inch overall length suits shallow collar and hub applications

Compatibility

Designed as a standard-specification set screw for any tapped 3/8-16 UNC threaded hole requiring a cone point fastener in mechanical assemblies, collars, and shaft-mounted components.

Installation Notes

Installation is performed by threading the set screw into a pre-tapped 3/8-16 UNC hole using a 3/16-inch hex key. Ensure the shaft or mating surface is properly positioned before fully seating the cone point, as it will indent the surface upon tightening. Follow applicable torque guidelines for the assembly per the equipment manufacturer or applicable ASME standards. Use appropriate thread-locking compound or seating procedures as dictated by the application to prevent loosening under vibration.
