Value Collection 131196PR Set Screw 1/2-13 X 3/4 in Oval Point

Product Description

The VALUE COLLECTION 131196PR is a Grade 8 alloy steel set screw designed for high-strength clamping and locking applications in mechanical assemblies. This socket set screw features a 1/2-13 UNC thread, measures 3/4 inches in overall length, and uses an oval point tip that allows it to seat against a surface with reduced marring compared to flat or cup-point designs. Driven by a 1/4-inch hex key, it conforms to ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance mechanics routinely install this type of fastener to secure collars, pulleys, gears, and similar components onto shafts.

This set screw is suited for general industrial, manufacturing, and mechanical maintenance environments where a flush or recessed fastener is required. The oval point makes it a practical choice when repeated removal and reinstallation is anticipated, as it bears against the mating surface without fully penetrating or deforming it. It is appropriate for use in both light and heavy machinery where a Grade 8 alloy steel fastener is specified by design or maintenance requirements.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Oval point tip reduces surface damage during clamping compared to cup or cone points
• 1/2-13 UNC thread form for broad compatibility with standard tapped holes
• 1/4-inch hex socket drive for use with standard Allen or hex key tools
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Fully recessed socket head allows flush installation in counterbored assemblies

Compatibility

Designed as an OEM-style replacement or standard-stock set screw for any mechanical assembly requiring a 1/2-13 UNC threaded socket set screw with an oval point and Grade 8 alloy steel material specification.

Installation Notes

Installation is typically performed by machinists, millwrights, or qualified maintenance mechanics using a 1/4-inch hex key or Allen wrench. De-energize and lock out any machinery before servicing components that use set screws. Ensure the mating tapped hole is clean and free of debris before threading the screw in by hand to confirm engagement before applying final torque. Refer to the applicable machinery manufacturer torque specifications for Grade 8 fasteners at this thread size.
