Value Collection 151343PR Set Screw 1/2-13 X 5/8 in Flat Point

Product Description

The VALUE COLLECTION 151343PR is a flat point set screw designed for secure, non-permanent clamping and positioning applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this 1/2-13 UNC threaded fastener measures 5/8 inches in overall length and is driven with a 1/4-inch hex key. Its flat point distributes load across the mating surface without marring, making it well suited for locking collars, hubs, and shaft components where surface integrity matters. Conforms to ASME/ANSI B18.3 and ASTM F912 standards. Installed by machinists, millwrights, and maintenance technicians across industrial and commercial equipment.

This set screw is used in mechanical power transmission assemblies including shaft collars, gear hubs, pulleys, and similar rotating components in industrial machinery, HVAC equipment, and general manufacturing equipment. The flat point style is appropriate where the mating shaft or component must not be deformed or dimpled. It is a standard UNC fractional-inch fastener, compatible with common 1/4-inch hex key tooling.

Key Features

• Flat point design prevents marring or deformation of mating shaft surfaces
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 1/2-13 UNC thread for broad compatibility with standard tapped holes
• 5/8-inch overall length suits moderate-depth engagement applications
• 1/4-inch hex drive accepts standard hex keys and Allen wrenches
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and material standards

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for any mechanical assembly requiring a 1/2-13 UNC flat point set screw with a 1/4-inch hex drive in a 5/8-inch overall length.

Installation Notes

Set screws of this type are installed by machinists, millwrights, or maintenance technicians using a calibrated hex key. Ensure the tapped hole is clean and free of debris before installation. Always de-energize and lock out equipment before servicing any rotating assembly. Do not overtighten, as Grade 8 alloy set screws can strip smaller tapped holes if torque is not controlled.
