Hillman Carriage Bolt, 3/8 in x 3-1/2 in, Grade 2, Hot Dipped Galvanized, Steel, Round Head, Coarse Thread, 50/CT

Built for outdoor jobs that need a steady hold and a clean finish.

Coarse thread and hot dipped galvanized steel for work that faces weather without the fuss.

Product Overview:

When you are working outside, the hardware has to pull its weight. This carriage bolt gives you a plain, dependable fix with Grade 2 steel and a hot dipped galvanized finish, so it stands up well in decks, docks, and other exposed spots. The round head sits clean, the coarse thread bites in with a sure feel, and the 3/8 inch by 3-1/2 inch size fits common outdoor builds without much drama. It is approved for treated lumber too, which is handy when you want the job done right the first time. Picture the assembly settling in tight, with less squeak and more calm.

Key Features:

• Grade 2 steel: Gives you a straightforward fastener that handles everyday outdoor building work without making a song and dance about it.
• Hot dipped galvanized finish: Adds a weather ready layer that helps the bolt hold up where rain, splash, and damp air show up.
• Coarse thread: Grips fast in wood, so you get a firmer pull and a steadier fit when the pieces start to come together.
• Round head design: Leaves a neat top side, which matters when you want the build to look tidy instead of clunky.
• Approved for treated lumber: Works with the kind of material you often reach for on outdoor projects, so you can set it in place and get moving.
• 50 count box: Keeps a decent supply on hand for repeat jobs, which saves you from running back mid project, and that is a relief.
