Bolt Nuts for Carbon Steel Pipes

Bolts with Hex Heads

A hex bolt’s hexagonal head serves as a surface for grasping or twisting the bolt with a wrench, socket and ratchet, or drill/driver. Some hex bolts have threads that extend the whole length of the shank and are often used in threaded holes. They provide high grip strength because they distribute tension over the whole bolt. The thicker, unthreaded segment of a partially threaded bolt provides strength to the fastening process. Partially threaded hex bolts are also beneficial for operations that need more force to hold the workpieces together. Hex-head bolts are commonly used in construction and automotive applications.

Carriage Bolts

The domed head of a carriage bolt provides it with a smooth, polished appearance. It also adds a layer of safety and security since it does not have a driving surface like a hex-head bolt. Carriage bolts are fastened with washers and hex nuts after being inserted into pre-drilled holes. The nut is secured to the workpiece by a square area under the head, allowing you to attach it with a single wrench, socket, or driver bit. Carriage bolts are used in a wide range of applications, such as decks, furniture, and outdoor playsets.

Anchor Bolts

Anchor bolts are classified as either those meant for use in concrete foundations or those intended for use in a wall. L-bolts are intended for usage in wet concrete. While the concrete cures, the bolt is kept in place. L-bolts may be used to secure a deck post to a concrete pad. To secure retrofit anchor bolts in existing concrete, an adhesive is employed. When drilling into a wall stud is not possible, toggle bolts provide support for hanging things.

U-Bolts

U-bolts have two threaded shanks with a rounded or flattened appearance. Rounded U-bolts are used to secure pipe or conduit to a surface, while squared U-bolts are used to fasten things to a surface, such as a square post. The U-bolt is held in position against the item being secured by two nuts and a metal plate.

Eye bolts

Eye bolts have a loop or ring end and a threaded end for attaching a chain or rope to a wood, metal, or concrete surface. Eye bolts are designed to be used in pre-drilled holes and come with a matching nut. Screw eyes are similar in appearance but have coarser self-tapping threads and a pointed tip that enables them to be driven into a pilot hole in a woodwork item.

Stud Bolts

Stud bolts are threaded rods with threads on both ends, used to secure flanges together in piping systems or other applications where a nut is required on both ends of the bolt. They are commonly used in oil and gas, petrochemical, and power generation industries.

Lag Bolts

Lag bolts, also known as lag screws, have a coarse thread and a hexagonal head designed for use with a wrench or socket. They are used for securing heavy materials to wood, such as attaching lumber to concrete or wood-to-wood connections.

Tension Control Bolts

Tension control bolts feature a unique design with a spline section beneath the head and a cone-shaped washer. They are installed using a specialized wrench that breaks off the spline after reaching the proper tension, providing a reliable and controlled bolt preload. They are commonly used in structural steel connections.

Flange Bolts

Flange bolts have a washer-like flange under the head that distributes the load and provides a larger bearing surface. They are commonly used in automotive, plumbing, and machines.

Types of Nuts

In the industrial sector, there are various types of nuts used for fastening components together. Here are some common types of nuts:

Hexagon Nuts

Hex nuts have a six-sided driving surface. They are a common sort of nut used to connect wood and metal components with bolts of the same size and thread type.

Lock Nuts

Nylon lock nuts have a hexagonal head with an integrated nylon ring. When you tighten a lock nut onto a bolt, the threading of the bolt displaces or deforms the ring, causing friction and preventing loosening from slippage or vibration. A castle nut is a kind of locking nut that works by putting a pin or clip into a hole in the bolt. Rotation is restricted when notches etched into the nut come to rest on the pin.

Wing Nuts

Wing nuts are designed to be tightened and loosened without the need of tools; the wings allow you to tighten and loosen them with your thumb and finger. These nuts are used to make adjustments and removals quick and easy. They may be found on drum sets, light stands, and other items that need to be adjusted on a regular basis.

Cap Nuts

Cap nuts, sometimes known as acorn nuts, are domed and feature a hexagonal driving surface. They are often hand installable. They screw onto the exposed threads of a bolt or threaded rod to protect them and provide a decorative look. Cap nuts may be found in projects like outdoor playsets and fences.

Square Nuts

Square nuts have four flat sides and are designed to be used with square bolts or in channels or tracks where rotation prevention is required. They are commonly used in construction, machinery, and automotive applications.

These different types of nuts cater to specific performance advantages and application scenarios in various industries, ensuring secure fastening of components based on specific requirements and usage scenarios.
