Value Collection 30597 Hex Cap Screw 3/8-16 Grade 316 Ss

Product Description

The VALUE COLLECTION 30597 is a partially threaded hex head cap screw designed for general mechanical fastening in corrosion-resistant applications. It features a 3/8-16 UNC thread and measures 2-1/4 inches in length under the head. Manufactured from Grade 316 stainless steel with a bright uncoated finish, this fastener offers strong resistance to chlorides, moisture, and mild chemical exposure. It is installed using a standard hex wrench or socket driver. Maintenance technicians, pipefitters, and millwrights commonly use this fastener wherever stainless hardware is required to meet corrosion or sanitary standards.

This fastener is suited for use in wet environments, marine-adjacent installations, food-processing equipment, pool and water treatment equipment, and HVAC or plumbing assemblies where standard zinc-plated hardware would corrode prematurely. The 3/8-16 UNC thread pattern is one of the most common inch-series coarse-thread sizes, making this screw a frequent replacement or service part across a wide range of commercial and industrial equipment. Partial threading allows the unthreaded shank to serve as a precise locating or bearing surface in bolted joints.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet or chloride-rich environments
• 3/8-16 UNC coarse-thread pattern for broad compatibility with standard inch-series tapped holes
• Partial threading provides an unthreaded shank section for use as a locating or load-bearing surface
• Bright uncoated finish — no risk of coating delamination or galvanic incompatibility with stainless hardware
• 2-1/4-inch length under head accommodates moderate-depth bolted assemblies

Compatibility

Designed as a standard inch-series hex head cap screw for any application requiring a 3/8-16 UNC partially threaded fastener in Grade 316 stainless steel.

Installation Notes

Install using a properly sized hex socket or open-end wrench. Always verify thread engagement depth and torque to the equipment manufacturer's specification for 3/8-16 stainless fasteners. Avoid contact with dissimilar metals in highly conductive or submerged environments to minimize galvanic corrosion risk. Power down or depressurize any assembly before removing or replacing structural fasteners.
