Screws and Nuts – Precision Fasteners by Ashish International
Screws and Nuts Manufacturer & Supplier in India
Screws and nuts are fasteners used to join, fix, and hold parts together in machines, structures, and support systems. A screw is a threaded fastener that turns into a material or a nut to clamp parts tightly, while a nut is a threaded block that pairs with a bolt or screw to lock a joint in place. Together with bolts and washers, screws and nuts are the basic building blocks of almost every assembly, from a steel frame to an electrical panel. They come in many types, sizes, and materials, and in finishes that resist rust. In MEP (mechanical, electrical, and plumbing) and support work, the right screws and nuts hold channel, brackets, and clamps firmly together. Ashish International is a screws and nuts manufacturer and exporter based in Ludhiana, India, with over 25 years of experience producing fasteners and support fittings to global quality standards. Choosing quality screws and nuts keeps every joint strong and secure.
What are screws and nuts?
Screws and nuts are two of the most common fasteners used to hold things together. A screw has a thread a spiral groove running along its body, so it can bite into a material or screw into a nut and pull parts tight. A nut is a small block with a threaded hole that matches a bolt or screw; when the two are tightened, they clamp the joint firmly. Used with washers and bolts, they make joints that can be tightened, loosened, and reused. In support systems, screws and nuts fix strut channel, brackets, and clamps together, and they appear in almost every product on the Ashish International products page. They matter because a joint is only as strong as the fastener holding it. For example, a single channel support may use several nuts and bolts to lock a bracket and clamp in place. Screws and nuts are threaded fasteners that clamp parts together to make strong, reusable joints.
What is the difference between screws, nuts, and bolts?
People often group screws nuts and bolts together, but each has a distinct job. A screw is a threaded fastener that usually turns directly into a material like wood, metal, or plastic or into a threaded hole, using its own thread to grip. A bolt is also threaded, but it is normally used with a nut: the bolt passes through the parts and the nut tightens on the other side, clamping them together; a foundation or anchor bolt is one example. A nut is the threaded block that pairs with a bolt or screw to complete the joint. A long threaded bar with no head, called a stud or threaded rod, takes a nut at each end. In short, when people say nuts bolts and screws, they mean the family of threaded fasteners that hold assemblies together. For example, a bolt and nut clamp two plates, while a self-tapping screw fixes a sheet straight to a frame. A screw grips a material, a bolt pairs with a nut, and a nut completes the joint.
What are the types of screws and nuts?
There are many types of screws and nuts, each made for a different job. They are usually grouped by how they grip and what they fix.
Common screws
Machine screws fix into a threaded hole or nut and are used in machines and panels. Self-tapping screws cut their own thread into sheet metal or plastic. Set screws lock a part onto a shaft. The right screw depends on the material and the load.
Common nuts
Hex nuts are the standard six-sided nuts used with bolts everywhere. Lock nuts (nylon-insert or all-metal) resist loosening under vibration. Wing nuts can be tightened by hand for quick adjustment. Each type matches a different need for strength or speed.
Specialty nuts: cage, channel, and more
Some nuts are made for special jobs. Cage nuts and screws are used in server racks and panels, where a square nut sits in a spring cage clipped into a rail. Channel and spring nuts lock into strut channel for support systems. For unusual sizes or shapes, custom fabricated fasteners can be made to order.
Types of screws and nuts range from machine and self-tapping screws to hex, lock, cage, and channel nuts.
Where are screws and nuts used?
Screws and nuts are used in almost every industry, because nearly everything built from parts needs fasteners to hold it together. In MEP and support work, they lock strut brackets, pipe clamps, and beam clamps onto channel, and fix cantilever arms to uprights. In machinery, they hold parts, panels, and covers; in electrical work, they secure enclosures, racks, and cable supports; and in construction, they join steel and fix fittings. The right fastener for the job keeps assemblies safe and easy to service, since a bolted joint can be undone for maintenance. Using the wrong size or grade, by contrast, can lead to loose or failed joints. For example, a vibrating machine needs lock nuts so its bolts do not shake loose over time. Screws and nuts hold together MEP supports, machinery, panels, and steel structures across every industry.
How to choose a screws and nuts manufacturer and supplier?
Choosing the right screws and nuts and a reliable maker keeps every joint strong. First, match the fastener to the job the right type, size, thread, and grade for the load and material. Get the thread and size right, since a mismatched screw and nut will not hold. Next, choose the material and finish: galvanized or plated mild steel for general use, or stainless steel for damp or corrosive sites. Quality is critical, because a weak or badly threaded fastener can fail; look for screws and nuts manufacturers that match the strength and accuracy of established global brands, run a certified, quality-controlled facility, and back their products with proper quality assurance. A good supplier should offer a wide range from one place and handle both bulk and urgent orders. Finally, ask about custom or white-label production for special fasteners or your own brand. For example, sourcing channel, clamps, and fasteners from one maker ensures every thread matches. Choose screws and nuts by type, size, grade, and a manufacturer with proven quality control.

Q2. What is the difference between a screw and a bolt?
A screw usually turns directly into a material or a threaded hole, using its own thread to grip. A bolt is normally used with a nut, passing through the parts so the nut can tighten and clamp them together.
Q3. What are the main types of nuts?
Common nuts include hex nuts for general use, lock nuts that resist vibration, wing nuts for hand tightening, cage nuts for racks and panels, and channel or spring nuts that lock into strut channel.
Q4. What is a cage nut?
A cage nut is a square nut held in a spring-steel cage that clips into the square holes of a rack rail or panel. It is used with a matching screw to mount equipment in server racks and enclosures.
