Introduction to Heavy Hex Nuts

Heavy hex nuts are six-sided internally threaded fasteners, larger versions of common/standard hex nuts. They are primarily used in structural applications and are often paired with bolts to securely secure two or more materials together.
Manufacturing Process:
Hex nuts are molded from steel or stainless steel in various grades and are designed to withstand high temperature and pressure. They are typically dipped in zinc or mechanically galvanized to enhance corrosion resistance.
Available Sizes:
Hex nut sizes range from 7/16" and smaller to a maximum of about 3.25" and larger, depending on the material. Nuts in the 7/16" to 3.25" range are doubled chamfered (beveled); nuts larger than 7/16" may have a washer face bearing (bottom) surface and a chamfered top.
Hex nuts are available in several sub-types that differ based on the material and finish. They are also manufactured in different grades and astm specifications to suit specific applications.
Thread Type:
Heavy hex nuts are available in a variety of thread types. The most common are metric standard, hex, and socket nuts.
Stainless steel heavy hex nuts are typically used in a number of sectors, such as marine, construction, and industrial, where the fastener needs to endure severe pressure. These nuts are produced with thicker walls and threads to distribute the stress across a wider area, making them ideal for heavy loads.
They are also more durable than their lighter-duty counterparts and can withstand higher tensions and vibrations. They are a popular choice for securing larger, heavier items and can be installed without the need for other heavy-duty screws parts like studs or long bolts.
