Structural Bolts
Structural Bolts serve two main purposes: Connecting and securing parts in place.
Bolts are generally utilized as connectors to join together different sections of a product. Typically paired with nuts to help maintain and support the bolts.
Along with connecting different parts to structures, these bolts also help to secure the parts in place to ensure that they create a safe environment. To properly secure a part of a structure with the bolts, it is important to note how “snug” or tight the fit needs to be. Screwing the bolt in too much or too little could both have negative effects.
Structural bolts are an important and necessary part of building a sustainable infrastructure.
Nuts
Are you looking for the perfect pieces of hardware for a project? Perhaps you don’t know where to turn to find the bolts, pins, and other accessories that you need to finish up a project. Here at Centennial, you will find everything you need, including a variety of different types of NUTS. While they are just small pieces of hardware, nuts are some of the most important, as they keep things held securely in place. The following are some of the types of nuts that are available:
-
Acorn Caps – These are specifically used for both safety and appearance. For safety reasons, an acorn cap can be used to prevent the end of a bolt from cutting someone or something. For appearance, they make the finished project look neater without having the bolt hanging out.
-
Castles – These nuts are typically used for applications that are low-torque and are used as positive locking devices.
-
Locks – These include other types of hardware such as castles, and are great for locking a bolt in place. While there are different varieties available, all locks play an important role in keeping the bolt secure.
-
Square – Some applications call for a nut that is shaped a little differently. Square hardware is often used to avoid the sharp edges that appear on other nut types.
Washers
It's crucial to ensure that you have the appropriate materials for a construction project. There are various types of washers available, each designed for specific purposes. Below, you will find a summary of ten distinct washer types.
Different Varieties Washers can vary in shape, size, material, or design, such as:
-
Belleville washer: This washer has a slightly conical shape, allowing it to function as a spring.
-
Bevel washer: This washer is angled, making it ideal for use at an incline.
-
Bridge washer: This sturdy, oversized washer is suitable for use in wooden construction.
-
Cup washer: This washer has a recessed center that allows the bolt to sit flush.
-
Finishing washer: This washer is designed to create a smooth, polished finish for your project.
-
Flat washer: These versatile washers are the most commonly used type.
-
Lock washer: With teeth that prevent slipping or rotation, a lock washer is an excellent choice.
-
Neoprene washer: When a tight seal is required, a neoprene washer can provide a better grip than a metal washer.
-
Plate washer: A square washer provides a larger surface area for bearing than a round washer.
-
Torque washer: This washer has prongs on the underside to prevent slipping or rotation.
Rods & Studs
It might surprise some homeowners how much they ought to know about different types of construction materials in order to accurately carry out home improvement projects. You don't have to be a contractor to know what RODS & STUDS can be used for around your home.
Different Types for Different Projects
There are a lot of different types of rods & studs to choose from for all kinds of projects. You can get studs that are completely threaded, which is great if you need them to pass through something and can secure them with nuts on either side. Single end studs and double end studs are both perfect for anchoring. They have one end for driving into a material and another for screwing a nut in place. To secure your stud or rod, put it in place and then thread a washer (if needed) and a nut onto it.
Socket Head Cap Screws
A screw is a small tool that is designed to fasten two different materials together in order to provide support to a larger structure. Some screws are designed to fasten to complementary nuts via threads that are designed to fit together and secure the screw and nut together. Other screws are designed to secure directly to the object they are inserted into by cutting grooves directly into the soft material of the object that is being secured in place. Almost all screws are designed with a head on one end, which is typically flattened and allows for the screw to be physically turned and tightened. Some of the most demanding and high-heat mechanical projects require special screws called SOCKET HEAD CAP SCREWS.
What Is a Socket Head Cap Screw?
A socket head cap screw serves the same general purpose as a regular screw, but it is shaped differently and is designed specifically for very demanding applications. This type of screw has a hexagonal drive hole and a cylindrical head. It is a tension fastener of high strength that is often used in clamping assemblies and is designed to be very durable and reliable.
Coupling Nuts
Coupling Nuts are internally threaded fasteners used to connect two externally threaded rods. Essentially, this simple piece of hardware acts as a revolutionary bolt extension for those times when you need a little more room.
Variations
The hex design is the most common type of coupler. Similar to a standard hex bolt or hex nut, it has six flat sides that allow it to be tightened using a wrench. Basic versions are meant to join two rods of equal thread pitch and diameter.
A reduced coupling nut is a variation of the hex design. This joint connects two rods with different thread sizes, ultimately reducing or increasing the size of a bolt head.
The less common eye coupling nut is slightly different, as its entire assembly attaches to a beam or a truss, serving to vertically suspend a threaded rod or bolt.
Material
Most coupling nuts are made of carbon steel, which can be further galvanized or zinc-plated to reduce corrosion. Overall strength, as determined by ASTM, is based on size and material grade, assuming that the threaded distance is equal to or greater than the thread diameter.
Sizes
Size is determined by the width of the hole, or the externally threaded rod. Common sizes range from 3/8 " to 1 1/14" in diameter. Likewise, pitch refers to the distance between threads, which can be as high as 16 counts per inch. While joint also varies, most common applications settle for 1 to 3 inches.
Anchor Bolts
Hanging a shelf or picture on the wall can be an easy do-it-yourself project that only requires a few tools to get the job done. Many people, however, forget to use one of the most important supplies that can ensure that your decorations are securely fastened to the wall – WALL ANCHORS.
Staying Safe
If the item that you would like to hang on your wall is very heavy, there is a chance that a basic nail in drywall could pull free. This could result in injury to an individual or damage to your home. Solid wall anchors can ensure that your screw or nail is securely fastened either into the drywall or into a stud. If you have small children in your home, it is important that you use an anchor to keep photos up on the walls and the children’s furniture upright.
The Right Anchor
Different projects require the use of different types of anchors, so make sure that you know which one is the right option for the job you are doing. For example, construction anchors should be used for masonry projects that require heavy-duty fastening, while a self-tapping screw anchor is typically all that is needed to hang a picture frame.
Lindapter
An entirely new concept of connecting steel with the Lindsay Bolt Adapter. It was a fast, cost-effective and adjustable way to clamp steel beams together without time-consuming drilling or welding. Lindapter has evolved to become a world leading designer and manufacturer of steel clamping systems.
U Bolts
The first step in understanding when to use U BOLTS is becoming familiar with them. The bolt may be made from galvanized steel, bright zinc plated steel, or stainless steel. These fasteners are shaped like the letter U, with a pair of threaded arms that extend from the rounded base. The threaded ends are designed for use with screws and washers. In some cases, a crosspiece may be used to increase the security provided by the bolt. Just like other bolts, these fasteners are inserted into holes that have been pre-drilled.
The Right Fit for Many Applications
U bolts are about as versatile as they are strong, and they come in a large variety of sizes. Some of their most practical uses include:
-
Attaching items to poles, such as a utility pole
-
Securing wiring and cables to walls
-
Adding bolts to concrete surfaces (the rounded ends are sunk into wet concrete, with the threaded ends protruding from the surface)
-
Supporting pipework
-
Attaching signs to posts
-
Any general clamping
