Value Collection 151337PR Set Screw 1/2-13 X 1/2 in Flat Point

Product Description

The VALUE COLLECTION 151337PR is a Grade 8 alloy steel set screw designed for secure, flush-point fastening in mechanical assemblies. With a 1/2-13 UNC thread and 1/2 inch overall length, this flat point set screw applies clamping force without marring the mating surface. A 1/4 inch hex drive accepts a standard hex key for installation. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, this fastener is suited for use in industrial, HVAC, and trade equipment applications where reliable thread engagement and controlled point pressure are required.

This set screw is used in shaft-to-hub connections, collar positioning, and mechanical stop applications across residential and commercial equipment. The flat point design distributes load evenly and is preferred when the mating surface must remain undamaged. Typical install scenarios include motor shaft collars, pulley hubs, and adjustment mechanisms in HVAC equipment, pumps, and general mechanical assemblies. Installation is performed by licensed technicians or qualified maintenance personnel.

Key Features

• Grade 8 alloy steel construction for high tensile and proof load strength
• Flat point design prevents surface damage on mating components
• 1/2-13 UNC thread for broad compatibility with standard tapped holes
• 1/4 inch hex drive for use with common hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-use set screw for any application requiring a 1/2-13 UNC threaded flat point fastener with a 1/4 inch hex drive.

Installation Notes

Installation is typically performed by a qualified mechanic or maintenance technician using a calibrated hex key or Allen wrench sized to 1/4 inch. Ensure the tapped hole is clean and free of debris before threading the fastener. De-energize and lock out all rotating equipment before installing or removing set screws per applicable OSHA lockout/tagout procedures. Do not exceed the rated torque range for the thread size and grade as specified in applicable ASME standards.
