Questions And Answers On Hex Bolts

What Tool Is Used With A Hex Bolt?

A wrench or ratchet is most frequently used in the installation and adjustment of hex bolts, although a variety of tools will work with their hexagonal head shape. Grips will work as well.

They can be turned using hand tools in the case of lighter applications. Heavy-duty hex bolts will usually require electrically powered tools.

What Is The Difference Between A Hex Bolt And A Hex Cap Screw?

Hex bolts and hex cap screws have a few key differences. Hex cap screws are sometimes called finished hex bolts. Their body dimensions have tighter tolerances.

They have a chamfered end and a washer face on the underside of the head. This feature distributes load as the screw is tightened in place.

Hex bolts are somewhat similar in appearance but they have a flat end. They also lack a washer face below their head.

What Is A Hex Bolt?

Hex bolts are a type of structural fastener. They are characterized by a hexagonal head and machine threading. They are used with a nut and washer as part of a fastener assembly or they are installed directly into a tapped hole.

Hex bolts may sometimes be referred to as hex caps.

What Does A Hex Bolt Look Like?

Hex head bolts have a flat, hexagonal head shape and a fully or partially threaded shaft.

When these bolts are partially threaded, they will have a smooth neck that extends from below the head. The shaft has a flat end and will accommodate a hexagonal-shaped nut or a construction anchor.

What Are The Advantages Of Hex Bolts?

Hex bolts carry many benefits that are based primarily on their form. Their hexagonal head can be gripped from multiple angles.

They can be tightened and loosened by hand, in light-duty applications, or by using varied installation tools. They are versatile and tough, making them useful in many structures.

What Are Hex Bolts Used For?

Hex bolts are used to establish connections between wood, steel, and other types of materials in structural applications. They are a common fastener for building and infrastructure settings, with placements including docks, bridges, and highways.

Hex bolts that feature a forged head can be used in a headed anchor bolt assembly and will facilitate the attachment of various hardware to concrete.

What Are Hex Bolts Made From?

Hex bolts made for structural settings will usually be manufactured from construction-grade materials that include carbon steel, stainless steel, and similar alloys. Hot dipped galvanization and zinc-coating may be applied to enhance resistance.

Hex bolts meant for use in light-duty applications may be manufactured using a variety of materials, including rigid polymers and other non-metal materials.

What Are Heavy Hex Bolts?

Heavy hex bolts are used to attach heavy structural parts. They are construction components that facilitate steel to steel connections. ASTM specifications for heavy hex bolts include A325 and A490.

Diameters for these bolts will range from 1/2-inch to 1 1/2-inch. They also have shorter thread lengths than standard-duty hex bolts.

How Are Hex Bolts Measured?

Length and diameter are the main measurements of a hex bolt. The diameter measurement is taken across the thickness of the bolt’s shaft. The length measurement is taken from the bottom of the bolts head, at the start of the neck, to the end of the shaft.

To correctly pair a bolt to the dimension of an installation, the depth of the installation piece or parts should suit the bolt’s length, while the width should suit the bolt’s diameter.

Are Hex Bolts Fully Threaded?

Hex bolts include partially threaded and fully threaded options.

Partially threaded hex bolts will have a smooth portion that extends from the bolt’s neck and may run as much as half the length of the shaft. They are used when good alignment and enhanced shear resistance are needed.

Fully threaded hex bolts are used when heavy-duty holding is required.
