Value Collection 603387PR Set Screw 1/2-13 X 1-1/4 in Flat Point

Product Description

The VALUE COLLECTION 603387PR is a 1/2-13 x 1-1/4 inch flat point set screw manufactured from Grade 8 alloy steel. It is driven by a 1/4 inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards. The flat point style is suited for applications where the contact surface must not be marred or where the screw bears against a hardened surface. Thread pitch follows the UNC standard. Overall length is measured as 1-1/4 inches. Machinists, maintenance technicians, and mechanical assemblers install this fastener in shaft collars, hubs, pulleys, and similar mechanical assemblies.

This set screw is used in light and heavy industrial maintenance, general mechanical assembly, and machine shop applications. The Grade 8 alloy steel construction provides the high tensile strength required in clamping and locking applications where standard steel fasteners are insufficient. The UNC 1/2-13 thread size is a common standard dimension found across a wide range of mechanical components and tooling.

Key Features

• 1/2-13 UNC thread, 1-1/4 inch overall length for reliable clamping depth
• Flat point geometry prevents gouging or deforming the mating shaft surface
• Grade 8 alloy steel delivers high tensile and proof load strength
• 1/4 inch hex drive accepts standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards

Compatibility

Designed as a standard UNC replacement or new-installation set screw for mechanical assemblies requiring a 1/2-13 thread, 1-1/4 inch length, and flat point contact style.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 1/4 inch hex key. Verify thread engagement depth is adequate for the clamping load before tightening. De-energize and lock out any rotating equipment before servicing shaft assemblies that use set screws. Do not substitute a lower-grade fastener in applications requiring Grade 8 tensile strength.
