We offer a wide range of metal bolts and studs. What is the difference between screws and bolts?
Bolts can be described as long shafts with a distinct head on one side. These are generally partially threaded.
A fully threaded bolt is referred to as a screw.

Known as lag bolts or lag screws or coach screws, these are among the toughest fasteners used in the industry. These extremely sturdy fasteners are usually used to connect heavy lumber or other heavy materials that bearing intensive loads. Their distinctive feature is their huge size with their starting size being approx. 20mm long and about 6mm thick. Lag screws have sharp lead thread points and are usually hex head.
Resistance welded fasteners are materially binding and can potentially eliminate the need for laborious welding operations. Premium resistance weld fasteners allow for additional components to be attached to an existing metal part, while allowing the fastener itself to stay permanently attached. Some of the different types of weld fasteners include weld nuts, weld studs and weld pins. Weld fasteners are a good solution for creating a super-strong and permanent connection between steel and the fastener. CD Studs or Capacitor Discharge Weld Studs, are mainly used in sheet metal applications.
Machine Screws are often used with nuts but also often tightened into tapped holes (without nuts). They might be considered a screw, or a bolt based on the Machinery’s Handbook distinction. In practice, they tend to be mostly available in smaller sizes up to M8. A quality assured range of machine Screws is available with us in various head and drive styles.
Hexagon socket Drive Screws with hexagon socket head have proved their worth in the machine and apparatus construction fields.
A self-tapping screw is a screw which can tap its own hole as it is driven into the material.
Common features are the screw thread covering the whole length of the screw from tip to head and a pronounced thread hard enough for the intended substrate, often case-hardened.
Some self-tapping screws are also self-drilling, which means that, in addition to the tap-like flute in the leading threads, there is also a preliminary drill-like fluted tip that looks
much like the tip of a center-drill. These screws combine a drilling action and the fastener installation itself into only one driving motion (instead of separate drilling, tapping, and
installing motions); they are thus very efficient in a variety of hard-substrate applications, from assembly lines to roofing.
Self Clinching Fasteners are easy to install fasteners that provide load carrying threads in metal sheets too thin to be tapped.
They provide strong load bearing male or female threads in thin steel and aluminium panels. Installation is neat and easy.
Our broad product range includes many different types of nuts.
Regular Hex and Square Nuts
A washer is a thin plate & most commonly has a disk-shape with a hole in middle.
In addition, Washers are also used for locking a device and reducing the vibration. These locking washers are available in various types such as spring washers, star washers, multi-tooth washers, disc spring washers, wave washers, taper washers, safety washers etc.
These are available in Mild Steel, Spring Steel and Stainless Steel. Washers can be classified into 3 broad classifications
In machinery construction or product assemblies, locking elements are used to perform a restraining role in the mechanical assembly.
We offer a wide range of Locking Elements. These include locking Pins, Washers, Circlips, Lock Nuts, Shackles and Links, etc. They perform various functions all related to locking as part of a mechanical assembly. They are very useful components that are used to compensate for vibration, prevent lateral movement, constraint members, provide alignment etc.
Brass Moulding Inserts are solid Thread Inserts are widely used, most common is their usage in plastics at the moulding stage. They are used in many moulding processes. Injection Moulding, Compression, GRP, Extrusion Blow Moulding etc. Inserts can either be incorporated at the time of the moulding process, or be inserted as a post moulding operation.
These Press fit inserts are pressed into a component shortly after it has been molded. While the plastic is still warm and pliable, the insert is pushed into the part. When the plastic cools, the insert becomes fixed in place.
To meet the growing needs of the industry, we have added MicroFast, a special range of micro size screws and nuts to our extensive list of products.
We are stocking an elaborate range of fasteners and screws used in manufacture of furniture and wood working.
Every good fastener deserves a good tool for installing it. To enable this we offer a wide assortment of premium quality tools and bits.
Screws with machine threads for use with a nut or in a tapped hole.Machine screws that are slotted have the traditional slot that runs horizontally through the middle of the head and is intended for use with a flat blade screwdriver bit.
Self-tapping screws are different to traditional screws as they tap their own threads when screwed into either plastic, wood or metal.
The Slotted or Minus type drive can be said to be outdated but is still quite popular in India as many small and traditional trades are using this. Another reason for the continued
popularity is that many assemblies are still being done manually and workmen have the traditional screw drivers with them.
A Self-Drilling Screw is a Self-Tapping Screw with the added feature of a drill point. The drill point looks a lot like the point of a drill. It will drill a hole and form the mating threads in one operation.
Various Head Styles and types are available in different materials for use in a number of applications.
Locking nuts also refer too the vast range of nuts that are used for providing some sort of locking arrangement in an assembly.
These could be nuts that are used singly or in tandem to provide the locking effect.
Spring washers, sometimes called disc springs, are a subtype of washers. They lend their mechanical capabilities to the unique profile of the material: when subject to a load, the irregularities of the washer compress with a proportionate resistance to return to their pre-deflected shape.
Industrial pins are fasteners that are used to locate align or join components mainly in automobile and industrial machinery sectors.
What are SHACKLES…A shackle or a Link are primary locking fasteners, connecting links in all manner of rigging systems, from boats and ships to industrial crane rigging, as they allow different rigging subsets to be connected or disconnected quickly.
Closed-End Blind Rivets are a type of tubular rivet with a mandrel through the centre. Its most commonly used to secure and completely seal the hole of a joint. Its most distinctive benefit is its leak resistance ability in roofing, metal building or watertight applications.
These are also known as Pop Rivets/ Gun Rivets/ Break-Stem Rivets. Rivets are popular fasteners where sheets have to be riveted together. One end is called a mandrel that breaks off during installation with a specially designed tool. Used in various areas across the industries. As a steady mechanical fastener, the stainless steel blind rivets are resistant to oxidation and rusting.
Rivet head Diameter
The rivet flange diameter is stated at minimum and maximum dimensions.
General purpose rivet available in a wide range of materials and head styles.
Suitable for applications with normal load bearing requirements.
By far the most commonly used style of blind rivet due to the ease of use and low initial cost.
Closed-End Blind Rivets are a type of tubular rivet with a mandrel through the centre.
The large flange blind rivets are very useful for joining low density materials.
Multi-grip rivets are an outstanding alternative to standard-grip rivets. Though standard-grip rivets are often solid in their own right, a project may require something with more versatility and efficiency. They provide incredible versatility for your project. They fit an extensive range of grip sizes so that if thickness differs somewhat, whether thinner or wider, the rivet can accommodate the variance.
Structural Blind Rivets are designed to fix elements where a high resistance to both tensile and shear strengths are required.

The Tre-Go Blind Rivets are high strength rivets that are both vibration and weather proof through their fitted neoprene washer. Ideal for curved or uneven surfaces.
Peeled rivets are extremely versatile and necessary for joining softer materials without fracturing or distortions. These are particularly suitable for uneven surfaces or where oversized holes remain after repairs.
Aluminium Rivets – Lightweight with good corrosion resistance.
Steel Rivets – Stronger than Aluminium with a “flash” coating of Zinc. Low corrosion resistance.
The hammer drive blind rivet was specially designed for attachment of hard materials to solid wood and similar materials. As soon as the drive pin in the hammer drive blind rivet is struck, the end of the rivet splits into four sections that hold the materials together, while the borehole diameter is 0.5 mm greater than that of the rivet. Ideal for fixing profiles, insulation, etc, on construction materials. The rivets are set with a hammer or striking mechanism.
Rivets are popular fasteners where sheets have to be riveted together.
These are also known as Pop Rivets/ Gun Rivets/ Break-Stem Rivets.
