Value Collection 605387PR Set Screw 1/2-13 X 1-1/4 in Oval Point

Product Description

The VALUE COLLECTION 605387PR is a 1/2-13 UNC set screw with an oval point, manufactured from Grade 8 alloy steel for high-strength clamping and holding applications. At 1-1/4 inches in overall length, this fastener is driven with a 1/4-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards. The oval point geometry distributes contact force over a curved surface, reducing damage to the mating workpiece while maintaining firm, reliable holding torque. Machinists, millwrights, and maintenance technicians commonly use this type of fastener in shaft collars, pulleys, and mechanical assemblies requiring repeatable positioning.

This set screw is suited for industrial and mechanical maintenance applications where a flush or below-surface fastener is required. The UNC thread form and Grade 8 alloy steel construction make it appropriate for high-load, vibration-prone environments such as rotating equipment and power transmission components. It is packaged individually and sold in a minimum order quantity of 5 pieces, making it practical for both bench stock replenishment and production use.

Key Features

• Oval point reduces marring and damage to shaft or mating surface during tightening
• Grade 8 alloy steel provides high tensile and proof load strength
• 1/2-13 UNC thread for broad tooling and tapping compatibility
• 1/4-inch hex drive compatible with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below the workpiece surface

Compatibility

Designed as a standard 1/2-13 UNC set screw replacement or new installation fastener for shaft collars, hubs, pulleys, and mechanical assemblies requiring a Grade 8 oval point fastener per ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a properly sized 1/4-inch hex key. Ensure all rotating equipment is fully de-energized and locked out before servicing any shaft or collar fasteners. Do not exceed the rated torque range for the thread size and grade; use a calibrated torque wrench when specifications are provided by the equipment manufacturer. Inspect the threaded bore for damage or debris before installation.
