Value Collection R80326903 Hex Head Cap Screw 3/8-16x12

Product Description

The VALUE COLLECTION R80326903 is a partially threaded hex head cap screw designed for heavy-duty fastening applications where corrosion resistance and dimensional stability are critical. Sized at 3/8-16 UNC thread with a 12-inch length under head, this fastener is manufactured from 18-8 stainless steel with an uncoated finish. The partial threading configuration allows it to function as a shoulder-style fastener in applications that require a smooth shank for alignment, load distribution, or clearance fits. Installers working in corrosive or wet environments rely on 18-8 stainless construction to resist rust without surface coatings that can degrade over time.

This fastener is suited for use in plumbing, HVAC equipment mounting, pool and spa mechanical assemblies, electrical enclosure fabrication, and general industrial construction where a standard UNC 3/8-16 thread pattern is specified. The 12-inch length under head makes it appropriate for through-bolting thick material stacks, structural components, or equipment frames where shorter fasteners fall short. Sold individually per package with a minimum order quantity of 5 units.

Key Features

• 3/8-16 UNC thread provides broad compatibility with standard taps, nuts, and threaded inserts
• 12-inch length under head accommodates deep through-bolt applications
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Partially threaded shank allows for shear-load and alignment applications
• Uncoated finish eliminates coating thickness variation for precision fits
• Inch measurement system; length measured under head per standard convention

Compatibility

Designed as a direct-fit replacement or new-install fastener for any application calling for a 3/8-16 UNC hex head cap screw with a 12-inch length under head in 18-8 stainless steel.

Installation Notes

Install using a standard 9/16-inch hex wrench or socket driver sized for a 3/8-inch hex head cap screw. Verify thread engagement depth and confirm the mating nut or tapped hole is rated for 3/8-16 UNC before torquing. Power down or de-energize any associated equipment before fastening into electrical or HVAC assemblies. Do not mix stainless fasteners with dissimilar metals in submerged or highly conductive environments without consulting applicable codes for galvanic compatibility.
