Value Collection R80326981 Hex Cap Screw 3/8-16 X 6-1/2 in 18-8 Ss

Product Description

The VALUE COLLECTION R80326981 is a partially threaded hex head cap screw designed for secure fastening in structural, mechanical, and industrial applications. It features a 3/8-16 UNC thread size and a 6-1/2 inch length under head, making it well suited for assemblies that require a long grip length with a fully engaged threaded zone at the nut end. The fastener is manufactured from 18-8 stainless steel, providing corrosion resistance in wet, outdoor, and mildly chemical environments. The uncoated finish preserves the natural surface of the material. Machinists, maintenance technicians, pipefitters, and general contractors commonly use this size in equipment mounting, flange work, and structural framing.

This hex cap screw is appropriate for use in residential and commercial construction, HVAC equipment mounting, plumbing fixture installation, and general mechanical assembly where a standard UNC 3/8-16 thread pattern is specified. The partial threading provides a smooth shank section that resists shear loads and allows precise clamping in thick or multi-layer material stacks. It is sold individually with a minimum order quantity of 5 pieces.

Key Features

• 3/8-16 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• 6-1/2 inch length under head to accommodate thick assemblies and long grip requirements
• Partially threaded shank resists shear loading and allows controlled clamping force
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Uncoated finish retains natural stainless surface for applications where coatings are restricted
• Standard hex drive head works with common wrenches and sockets

Compatibility

Designed for use with standard 3/8-16 UNC inch-series hex nuts, washers, and tapped components in general mechanical and structural fastening applications.

Installation Notes

Installation should be performed by a qualified technician or tradesperson familiar with fastener torque requirements for 3/8-16 stainless steel hardware. Use a properly sized hex wrench or socket to avoid rounding the head. When fastening into tapped holes, verify thread engagement depth meets the requirements of the application before applying final torque. Avoid mixing stainless steel fasteners with dissimilar metals in corrosive environments where galvanic action may be a concern.
