At BoltCraft Manufacturing, we don’t just sell hex nuts—we deliver solutions for businesses that don’t have time for hardware failures.

That’s exactly what our hex nuts are for—reliable, rugged, and ready for action.

You’ve got deadlines to meet, and the last thing you need is a nut that strips, corrodes, or doesn’t fit quite right. Our finished hex nuts are precision-made for industrial, agricultural, and construction use—because we know that in your line of work, every bolt counts.

Hex Nut Dimensions That Fit Right, Every Time

There’s nothing worse than reaching for a nut and realizing it just doesn’t fit. Too tight, too loose—it’s a small thing, but it can throw off your whole project. That’s why every one of our hex nut dimensions is manufactured with surgical precision, ensuring a snug, secure fit whether you’re working on bolts, rods, screws, or custom fabrication.

We sell hex nuts that stick to the highest industry specifications, ensuring every hex nut meets nominal size standards for accurate across flats measurements. If your project needs something specific – we have it in stock. No guesswork, no second-guessing—just hex nuts that fit the first time, every time.

Hex Nut Sizes for Every Job—Big or Small

From delicate machinery parts to enormous structural beams, every job requires the right size for the right situation. That’s why our range of hex nut sizes covers everything from small machine screws to heavyweight industrial fasteners.

Need something for a precision-fit assembly line? We’ve got you covered with fine thread finished hex nuts that ensure reliable fastening for even the most sensitive applications. Tackling a massive construction project? Our larger hex nut sizes are built to handle the load—and then some.

Top Lock Nut Grade C Zinc—A Secure Grip That Won’t Budge

You ever tighten something down and still feel that nagging worry it might slip loose later? Yeah, not with this nut. Our Top Lock Nuts grips like a vice and doesn’t let go. Designed for high-stress environments—think heavy machinery, agricultural equipment, and industrial applications—this nut keeps everything locked in tight, even under serious strain.

Also available in a flange style too, it’s crafted from high-strength carbon steel, ensuring that the threads stay solid even under extreme pressure.

Finish Hex Nuts—Tough Finishes for Tough Jobs

Every project has its own unique challenges, and sometimes the little details, like the nut’s finish, make all the difference. That’s why we offer finished hex nuts in a variety of materials and finishes to suit every need:

• Grade 304 Stainless Steel – This one’s your go-to for marine projects, food processing plants, or any environment where moisture could be a problem.
• Grade 5 Zinc – It’s versatile, durable, and great for general industrial work.
• Grade 8 Zinc Yellow – Built for high-stress environments like construction/heavy equipment, offering exceptional strength.

Each nut we sell is designed with precise across flats width, proper thickness, and accurate corner angles to ensure reliable fastening every time. Every hex nut meets or exceeds industry specifications.

Hex Lock Nuts and Top Lock Nuts—Fight Back Against Vibration

Vibration is the silent killer of industrial machinery. One loose nut, and suddenly, you’re dealing with downtime, repair costs, or worse. Our hex lock nuts and top lock nuts are engineered specifically to handle those shaky environments. Here’s what we offer:

• Hex Lock Nut Nylon Insert Grade C Zinc Yellow – This nut adds extra grip thanks to a nylon insert, preventing loosening from movement.
• Hex Lock Nut Nylon Insert Zinc – Same reliable design, with corrosion-resistant zinc plating for enhanced durability.
• Top Lock Nut Grade C Zinc – All metal lock nut, designed with a special top locking mechanism equivalent to grade 8

Each lock nut meets or exceeds required specifications, ensuring precise dimensions across flats, correct thread pitch, and sufficient corner angles for secure fastening.

Machine Screw Hex Nuts and Flange Lock Nuts—The Unsung Heroes

Not every fastener needs to handle a thousand-pound load. Sometimes, you just need reliability for lighter-duty jobs, and that’s where our Machine Screw Hex Nuts Zinc shine. Perfect for securing small screws, they’re easy to install, easy to remove, and built to last with precise thread dimensions and consistent flat width.

For those jobs that need extra grip, our Non-Serrated Flange Lock Nuts Grade G Black Phosphate and Serrated Flange Hex Lock Nuts Zinc provide excellent resistance against loosening—no matter how much vibration your project throws their way.
