Value Collection C93053 Set Screw 3/8-16 X 5/8 in Grade 8

Product Description

The VALUE COLLECTION C93053 is a Grade 8 alloy steel set screw designed for high-stress fastening applications where a flush or below-surface installation is required. Featuring a knurled cup point, this screw bites into the mating surface to resist rotation and axial movement under load. The 3/8-16 UNC thread and 5/8-inch overall length make it a standard choice for securing collars, pulleys, gears, and similar components to shafts. A 3/16-inch hex key drive allows for precise torque application in confined spaces. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards. Supplied in a package quantity of 25 units.

This set screw is suited for use in mechanical assemblies found in HVAC equipment, motors, pumps, and general industrial machinery. The knurled cup point provides positive grip on both hardened and unhardened shaft materials. Grade 8 alloy steel construction gives it the tensile strength needed in vibration-prone environments such as fan assemblies, blower wheel hubs, and drive components. It is a standard UNC-threaded fastener appropriate for any trade or maintenance professional working with rotating mechanical assemblies.

Key Features

• Knurled cup point for positive grip and resistance to axial and rotational movement

• 3/8-16 UNC thread for compatibility with standard inch-series tapped holes
• 3/16-inch hex key drive for use in tight or recessed installation points
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Sold in a pack of 25 units

Compatibility

Designed as a standard 3/8-16 UNC set screw for use in any tapped hole or threaded collar requiring a 5/8-inch overall length Grade 8 fastener with a knurled cup point.

Installation Notes

Installation is performed with a 3/16-inch hex key. Ensure the mating threaded hole is clean and free of debris before installation. De-energize and lock out any equipment before accessing rotating assemblies. Do not substitute a lower-grade fastener in applications specifying Grade 8 tensile requirements.
