Value Collection -30604-45 Hex Head Cap Screw 316 Ss

Product Description

The VALUE COLLECTION -30604-45 is a hex head cap screw designed for industrial and commercial fastening applications where corrosion resistance is a primary concern. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, this fastener features a 1-8 UNC thread size and a 4.5-inch length under the head. The partial thread configuration provides reliable clamping force and is well suited for through-bolt and joint-fastening scenarios. Plumbers, pipefitters, marine contractors, and general trade mechanics working in corrosive or wet environments rely on Grade 316 stainless fasteners for their superior resistance to chlorides and saltwater exposure compared to Grade 304.

This cap screw is appropriate for use in environments subject to moisture, chemical exposure, or outdoor conditions. Typical applications include pipe flange assemblies, equipment mounting in wet mechanical rooms, marine and coastal installations, and food-processing or chemical-plant maintenance. The 1-8 UNC thread is a coarse thread standard, making it compatible with standard UNC-tapped holes and nuts of the corresponding size. The partially threaded shank allows the unthreaded portion to act as a precision bearing surface in bolted joints.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in chloride-rich and marine environments
• 1-8 UNC coarse thread standard for compatibility with standard tapped holes and nuts
• 4.5-inch length under head accommodates thicker flange or structural connections
• Partially threaded shank provides a bearing surface and improves shear-load performance in bolted joints
• Bright, uncoated finish maintains dimensional accuracy and allows inspection of the base material
• Hex drive head for use with standard wrenches and sockets — no special tooling required

Compatibility

Designed as a standard UNC hex head cap screw for use with 1-8 UNC tapped holes, nuts, and threaded inserts per inch fastening standards.

Installation Notes

Install using a properly sized open-end, box-end, or socket wrench matched to the hex head drive size. Ensure mating threads and tapped holes are clean and free of debris before installation. Grade 316 stainless fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound to threads before torquing. Follow applicable mechanical and structural codes for torque requirements based on joint material and application.
