All fasteners serve the same purpose joining and securing two or more components mechanically. However, variations in type, quality, shape, and material have a substantial impact on the performance and service life of fasteners. Understanding the functional differences between the available types of fasteners, such as nuts, bolts, and washers, is necessary for selecting the proper fastener (and fastener supplier) for your project.
At Prashaant Steel & Alloys, we’re proud to offer a wide range of stock and custom fasteners that are strong, work well, and are priced reasonably. This guide describes a few of the kinds of fasteners we have in stock to help you choose the best one for your fastening job.
TYPES OF FASTENERS
Prashaant steel & Alloys manufactures a variety of fasteners, including bolts, nuts, and washers.
TYPES OF BOLTS
Bolts are one of the most useful structural connectors because they can be made in so many different ways to work with different materials and meet different strength needs. Most of the differences between these fasteners are in the thread type, length, and shape of the head. Different combinations of these features make bolts with different functions. For fitting, they usually need a hole drilled and a matching nut or part that has been tapped. Unlike screws, they are usually not tapered. Most of the time, the names of different types of bolts aren’t consistent and are sometimes used wrongly for screws. Because of this, it’s best to choose bolts based on your project’s needs rather than the exact name on a supplier’s website.
Some of the types of bolts that we manufacture at Bolt & Nut include:
Carriage bolts: Carriage bolts have a rounded or countersunk head with a square bottom that keeps them from moving after they are installed. They are used a lot with wood and brick.
Flange bolts: Flange bolts are a special kind of hex head bolt with a flange built in that acts as a washer to spread the load more evenly.
Plow bolts: Similar to carriage bolts, some plow bolts have a square-shaped countersunk top. Others have a domed design. These bolts are great for heavy-duty uses like industrial machinery..
Hex head bolts/ Hex Head Cap Screw: Hex head bolts are a type of bolt with a hexagonal head. They are part of a larger group of bolts that must be tightened with a wrench. There are many different lengths and ways to thread them. Hex Head Cap Screws are the most popular type of Hex Bolt. They have tighter tolerances than other types.
Square head bolts: Like hex head bolts, square head bolts are named for the shape of their heads, which is square. This head’s shape makes it easier for tools to grip, which makes fitting easier.
Socket Head Cap Screws/ Allen bolt: Socket head cap screws have a flat, chamfered top surface and smooth or knurled cylinder sides. Forged, heat-treated alloys are examples of high-strength fasteners that are made for the most demanding mechanical uses and have special alloy formulations.
Additional bolt types: We can also make anchor, belt (such as eye, hook, J, and U), countersunk, lag, and T-handle bolts to your specifications.
TYPES OF NUTS
Nuts come in many different forms, sizes, thread patterns, and materials. Even though your choice of nut is somewhat limited by the bolt you choose, especially in terms of size and fitting, you should still choose the nut head shape and material that works best for your project.We carry the following kinds of nuts:
Coupling nuts: A connection nut is a longer, cylindrical nut that connects two male threads. This part can be added to a project to make it longer.
Flange nuts: Flange nuts, like flange bolts, have a round flange that serves as an external washer and promotes more uniform weight distribution.
Hex nuts: Hexagonal in form are hex nuts. Although these bolts have a huge range of applications, installation calls for a wrench. Finished, semi-finished, hex flange, hex jam, hefty, and slotted hex nuts are among the varieties of hex nuts we offer.
Lock nuts: Lock nuts are used to hold other nuts in place and stop them from coming undone. They come in a variety of forms. Serrated Hex Flange, All Metal Lock Nuts with Top or Side Locking Features, and Nylon Inserts are some varieties of lock nuts.
Slotted nuts: Slotted nuts are made and built so that a cotter pin or a safety wire can be used to lock them together.
Square nuts: The square form of a square nut is what makes it a square nut. This head form makes the fastener have more surface area and more friction, which makes it less likely to come loose.
Wheel nuts: Wheel nuts are a large group of nuts that are used in different ways on car wheels.
Additional nut types: We can also make cap, castle, cone, Keps, thumb, and wing nuts to your specifications.
TYPES OF WASHERS
Washers are disk-shaped parts that work with other screws to give you more control over locking and friction. For more specific uses, these fasteners may also have teeth, indentations, and other structures that make them unique. In general, they do many things, like keep the fastener assembly from coming loose, cover the surface under the fastener, and spread the pressure more evenly during installation and use.
Compared to nuts and bolts, there are a lot less kinds of washers. But there are still important differences between the different types of washers. Like nuts, washers should go with the bolt you choose and be chosen for your specific fitting task.
Our range of standard washers includes:
Beveled washers: Beveled washers are formed with a slightly angled surface, allowing them to join materials that are not parallel to one another.
Flat washers: Flat washers are the most popular kind of washer. They have more surface area, which makes it easier to spread the load. There are different widths for different hold strengths.
Lock washers: Lock washers come in many different forms, like helices, toothed rings, cones, and springs. Each is made to stop fasteners from slipping in tough situations. They are often used in places where there is a lot of shaking.
Structural washers: Structural washers are one of the most heavy-duty washers you can buy. These thick screws are made to stand up to the heavy loads that come with building.
OTHER FASTENERS
Bolt & Nut also sells other types of fasteners, like dowels, hose and shaft couplings, nails, pins, rivets, rods, screws, shackles, and studs, both in stock and as special solutions.
EXTRA INFORMATION ABOUT FASTENERS
NBN suggests that you talk to a tech to figure out which fasteners to use in a given situation. When choosing a clip, there are a lot of things to think about. Other important things to think about are how each fastener works with the others to make a joint, use cases, thread patterns, and material and finishing choices. In the long run, hiring an engineer will save you money and stress.
Fasteners find use in a variety of industrial applications, including:
Agriculture: In the agricultural business, fasteners are used in field irrigation and filtration systems, drying units, and other farm equipment, buildings, and grain bins.
Automobiles and transportation: Fasteners are used to put together a wide range of vehicles, including cars, trucks, airplanes, and specialized building equipment.
Building and construction. Scaffolding and other support structures used in building and construction need a lot of fasteners to stay stable while in use.
Chemical refining. In chemical factories, high-performance, corrosion-resistant materials like stainless steel, tool alloys, and exotic metals are used to make fasteners. They are used in heat exchangers, tanks, and processing systems, among other things.
Marine. For marine decks, ramps, bulkheads, and tanks to endure prolonged exposure to saltwater, fasteners used in the industry must have excellent corrosion resistance. Materials such as stainless steel and aluminum are commonly used for marine fasteners.
Military. Military bolts are made to work in places with high temperatures, corrosive chemicals, and a lot of stress. Heat exchangers, pumps and engines for equipment, and processing equipment are all common uses.
Oil and gas. Like military fasteners, fasteners used in the oil and gas businesses must work well under high stress and corrosive conditions. These fasteners are used in handling equipment such as drilling rigs, tanks, and pumps.
Power generation. Fasteners for the power generation business are made of strong, corrosion-resistant materials like aluminum, copper, nickel alloys, stainless steel, and other steel alloys. Typical uses are in electrical tools, exhaust systems, motors and pumps, and storage containers.
RIGHT-HANDED VS LEFT-HANDED THREAD PATTERNS
Numerous fasteners, such as nuts and bolts, have threads to facilitate their function as fasteners. There are both right-handed and left-handed thread patterns available. Special circumstances necessitate left-handed (i.e., counterclockwise running) threads to resist forces that would otherwise cause the fastener to become loose.
FASTENER MATERIAL SELECTION & PLATING GUIDE
Fasteners come in a wide range of materials and styles. It is just as important to choose the right type, size, and style of fastener as it is to choose the right material and material finish.
Aluminum, carbon steel, and other alloys are the most popular types of materials used for fasteners. But makers also make fasteners out of other materials, like brass and plastic, for use in specific situations. For instance, silicone bronze is ideal for aquatic environments.
Finishing choices are also available to improve the look or function of the material, like making it stronger or less likely to rust. Some of the plating choices we offer for finishing are black oxide, hot-dip galvanizing, zinc plating, and chrome plating.
