Value Collection R68449264 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R68449264 is a hex socket cap screw designed for fastening applications that demand corrosion resistance and reliable clamping force. Machined from 18-8 stainless steel, this fastener features a 5/8-11 UNC thread and measures 2 inches in length under the head. Drive engagement is through a 1/2-inch internal hex socket, which accepts a standard Allen or hex key drive tool. This screw is suited for maintenance, fabrication, and mechanical assembly work across industrial, commercial, and trade service environments. Licensed tradespeople and skilled technicians install these fasteners wherever a socket-drive cap screw profile is required.

This screw is a general-purpose fastener appropriate for use in structural, mechanical, and equipment assembly applications. The 5/8-11 UNC coarse thread is compatible with standard inch-series tapped holes and nuts of the same designation. The 18-8 stainless steel construction makes it a practical choice in wet, outdoor, or mildly corrosive environments such as HVAC equipment enclosures, plumbing supports, pool equipment frames, and general mechanical assemblies where carbon steel fasteners would be subject to rust or staining.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• 5/8-11 UNC coarse thread for compatibility with standard inch-series tapped holes and nuts
• 2-inch length under head suits moderate-depth fastening applications
• 1/2-inch internal hex socket drive for secure torque transfer with Allen or hex key tools
• Socket cap head profile allows installation in recessed or space-constrained locations

Compatibility

Designed as a standard replacement or stocking fastener for applications requiring a 5/8-11 UNC hex socket cap screw in 18-8 stainless steel.

Installation Notes

Installation is performed with a 1/2-inch hex key or Allen driver; confirm the driver is fully seated before applying torque to avoid rounding the socket. Verify that the mating tapped hole or nut is also 5/8-11 UNC before driving the fastener. Inspect threads for damage or contamination before assembly. Stainless steel fasteners are susceptible to galling — applying an appropriate anti-seize compound to the threads is a common field practice to prevent seizure during installation or future removal.
