Value Collection R56000268 Hex Head Cap Screw 7/8-9 X 5 in

Product Description

The VALUE COLLECTION R56000268 is a fully threaded hex head cap screw designed for industrial and trade fastening applications. Machined to 7/8-9 UNC thread specification with a 5-inch length under head, this fastener is manufactured from Grade 316 stainless steel with no additional coating. Grade 316 stainless provides elevated corrosion resistance compared to Grade 304, making it suitable for wet, chemical, or marine environments. The hex drive head accepts standard hex wrenches and sockets. At 0.4 pounds, it is a solid, full-bodied fastener intended for structural and mechanical assembly work.

This cap screw is used across a wide range of commercial and industrial applications where corrosion resistance is required. Common installation scenarios include marine hardware, food processing equipment, chemical processing systems, HVAC structural assemblies, plumbing equipment mounts, and outdoor or coastal installations. The UNC (Unified National Coarse) thread form is the standard for most inch-series fastener applications in North America, ensuring broad compatibility with tapped holes and standard hex nuts of the corresponding 7/8-9 thread size.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in harsh or wet environments
• Fully threaded along the full 5-inch length under head for maximum thread engagement
• 7/8-9 UNC thread form conforms to Unified National Coarse inch-series standards
• Uncoated finish maintains dimensional accuracy and avoids coating interference in tight tolerance applications
• Hex head drive accepts standard hex sockets and wrenches for torque application

Compatibility

Designed as a standard inch-series UNC hex head cap screw for use with any 7/8-9 tapped hole, hex nut, or coupling nut conforming to UNC thread standards.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or trade professional using a calibrated torque wrench or impact tool sized for the hex head. Always verify that mating threads are clean and free of debris before installation. When installing stainless steel fasteners, apply an anti-galling lubricant or anti-seize compound to the threads to prevent galling and seizure during tightening. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being serviced.
