IMScrews 3/8-16 X 5-1/2" Carriage Bolts – Round Head & Square Neck, Full Thread, 304 Stainless Steel (18-8), Pack Of 1

About This Product

These IMScrews carriage bolts are heavy-duty fasteners built the right way.

Each one is 3/8-inch diameter by 5-1/2 inches long, with a 16-thread-per-inch pitch—that's the standard coarse thread for this size.

They're fully threaded from head to tip, which gives you maximum grip when you're tightening into wood, metal, or other materials.

The round head and square neck are classic carriage bolt design: the square neck bites into the material so the bolt won't spin when you're tightening the nut on the other side.

Made from 304 stainless steel (also called 18-8), they've got excellent corrosion resistance—rust is not a problem, indoors or out.

Great for deck building, furniture assembly, automotive repairs, or any project that needs a clean, strong mechanical connection.
Easy to install with standard wrenches or sockets.
Just drill your hole, pop it in, and crank down.

Solid, reliable, and ready for tough jobs.
