Value Collection R57001265 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R57001265 is a partially threaded hex head cap screw designed for secure fastening in structural and mechanical assemblies. Sized at 5/8-11 with a 3-3/4 inch length under head, it follows the Unified National Coarse (UNC) thread standard. Constructed from 18-8 stainless steel with no additional coating, this fastener resists corrosion in wet, chemical-exposed, or outdoor service environments. It is suited for use by industrial maintenance technicians, HVAC installers, plumbers, and general tradespeople who need a reliable, corrosion-resistant fastener for equipment mounting, pipe supports, or structural connections.

This fastener is appropriate for both light commercial and residential applications where a 5/8-11 UNC thread pattern is specified. The partial thread configuration provides a stronger grip in through-bolt and clamped-joint installations where the unthreaded shank bears shear load. Common install scenarios include equipment base mounting, unistrut and pipe hanger assemblies, mechanical room structural connections, and general trade fabrication work requiring stainless steel hardware.

Key Features

• 5/8-11 UNC thread size for compatibility with standard inch-system hardware
• 3-3/4 inch length under head for deep-grip fastening applications
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Partially threaded shank improves shear strength in clamped-joint assemblies
• Uncoated finish — no plating to chip, flake, or contaminate sensitive environments

Compatibility

Designed as a standard 5/8-11 UNC hex head cap screw compatible with any inch-system nut, tapped hole, or threaded insert using the same thread specification.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 5/8-inch bolt head. Ensure mating threads are clean and free of debris before driving. Apply thread lubricant or anti-seize compound appropriate for stainless steel to prevent galling, which is common with 18-8 fasteners under high torque. Power down or de-energize any adjacent equipment before working in mechanical or electrical enclosure environments.
