We offer a wide range of metal bolts and studs. While 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 as a Screw.
A stud is a fastener that uses a nut screw to increase or loosen tension between the parts it is fastening or holding together.
The work horse of any industry, the ubiquitous screw is needed in every machinery in some size or the other. We have a varied range to cater to all your different needs.

Square Neck Carriage Bolts
This is known by different names such as Carriage Bolts, Coach bolts/ Round Head Square neck bolt, Mushroom Head Square neck bolt etc. Useful for fastening wood and metal together.
- It is distinguished from other bolts by its shallow mushroom head followed by a square neck, while the shank cross section of the bolt is circular. This gives the bolt its self locking feature. The square neck grips into the part being fixed preventing the head from turning when the nut is tightened.
- Standard – DIN 603. Mild Steel and Stainless Steel

- WELD STUDS OR BOLTS
- 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. Where a fabricator may drill a hole to insert a bolt for an attachment point, a CD Stud can be shot to the attachment side with no reverse side marking or bolt head. This leaves a clean and well finished look to the product with no compromise in quality or strength and achieves a significant time and cost savings.
CD (capacitor discharge) stud welders utilize a capacitor storage system to produce a rapid electrical discharge, resulting in fast, high-integrity welds, even on thin-gauge materials. In contrast to arc welds, CD welds do not require ceramic ferrules or gas. The direct-current arc creates a shorter weld time, renders oxidation and heat concentration provided by ferrules and fluxes unnecessary.
These are suitable for use with Stud Welding Machines.
Our range of CD Weld Studs are as per DIN 32501/3 or ISO 13918.
- HSFG Structural Bolts
- HSFG bolts are also commonly used in structures that will be exposed to a lot of vibrations, or loadings that will reverse. Since the bolts are preloaded the tension in the bolt doesn’t vary as much as in a standard bolt, so they don’t fatigue as quickly.
- Tool Post Bolts
- Used for clamping on tool posts of a lathe.
