Value Collection 202794 Hex Cap Screw 1/2-13x3 316 Ss

Product Description

The VALUE COLLECTION 202794 is a fully threaded hex head cap screw sized at 1/2-13 x 3 inches, manufactured from Grade 316 stainless steel with no additional coating applied. It follows the Unified National Coarse (UNC) thread standard, making it a direct fit for standard inch-system fastener applications. The 316 stainless steel alloy provides strong resistance to corrosion, pitting, and chemical exposure, particularly in chloride-rich and marine environments. This fastener is suited for mechanical assemblies, structural connections, and equipment installations where long-term corrosion resistance is required. Installation is performed by maintenance technicians, pipefitters, millwrights, and other trade professionals working in industrial, commercial, or outdoor service environments.

This hex head cap screw is used in applications where a fully threaded fastener is needed across the full 3-inch length under the head. Typical installations include pipe flange assemblies, pump and motor mounting, HVAC equipment frames, pool equipment enclosures, and other service environments exposed to moisture, salt air, or chemicals. The uncoated 316 stainless finish is appropriate for food-service, marine, chemical plant, and outdoor settings where zinc or cadmium-plated fasteners would be unsuitable.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in harsh and chloride-heavy environments
• Fully threaded along the entire 3-inch length under head, maximizing thread engagement in thinner materials or stacked assemblies
• 1/2-13 UNC thread size provides wide compatibility with standard inch-system nuts, inserts, and tapped holes
• Uncoated finish eliminates concerns about coating compatibility with stainless nuts or food-grade applications
• Hex drive head accommodates standard wrenches and sockets for reliable torque application

Compatibility

Designed for use with standard 1/2-13 UNC inch-series nuts, washers, and tapped holes in stainless or compatible alloy components. Suitable as a replacement or service fastener in any assembly requiring a fully threaded 1/2-13 x 3-inch hex cap screw in 316 stainless steel.

Installation Notes

Shut down and de-energize any equipment before disassembling fastened joints. Use a calibrated torque wrench and apply fastener torque values specified by the equipment manufacturer or applicable code. When mating 316 stainless fasteners, apply an anti-seize compound to the threads to prevent galling, which is a common issue with stainless-to-stainless contact. Follow applicable mechanical codes and equipment service manuals for proper torque sequences on flanged or multi-bolt assemblies.
