Value Collection -30604-44 Hex Head Cap Screw 316 Ss

Product Description

The VALUE COLLECTION -30604-44 is a partially threaded hex head cap screw sized at 1-8 x 4 inches, manufactured from Grade 316 stainless steel with an uncoated finish. Grade 316 stainless steel provides elevated corrosion resistance compared to Grade 304, making it well suited for wet, chemical, or marine environments. The UNC (Unified National Coarse) thread standard ensures broad compatibility with standard inch-series fastener applications. Partial threading allows the unthreaded shank to act as a shoulder or pivot point where needed. This fastener is installed by maintenance professionals, contractors, pipefitters, and fabricators working across a range of industrial and commercial applications.

This hex head cap screw is appropriate for structural fastening, equipment assembly, and process piping or chemical handling installations where corrosion resistance is a priority. The 4-inch length under head and 1-8 thread size make it a common choice for heavier mechanical connections in both indoor and outdoor settings. Minimum order quantity is 5 pieces.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in harsh and wet environments
• UNC thread standard for compatibility with standard inch-series nuts and tapped holes
• Partially threaded shank provides a bearing surface for shoulder or pivot applications
• Uncoated finish maintains base material corrosion properties without additional coating variables
• Hex drive head for installation with standard wrenches or sockets

Compatibility

Designed for use with standard UNC 1-8 inch-series nuts, threaded inserts, and tapped holes in structural, mechanical, and process equipment assemblies.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for the head. Always verify thread engagement depth and mating thread condition before final torque. When fastening into stainless steel components, apply an appropriate anti-seize compound to prevent galling between mating stainless surfaces. Follow applicable mechanical or structural codes for torque and fastener specifications.
