A bolt is a threaded fastener that is tightened with a nut to hold parts together. Aniket Engineering manufactures custom bolts to your drawing at our manufacturing site in Mumbai, from small prototype quantities to large production runs.
Bolt head shapes we make
We make bolts with hexagonal, square and round heads, as your design requires. Hexagonal heads are the most widely used, because a spanner can engage them from several angles. Square heads suit applications where the head is held or seated against a stop. Round heads give a smooth, low-profile finish.
Materials and grades
The grade of a bolt is chosen according to its end application, so the first question is always what the bolt has to do. We turn bolts from:
- Stainless steels
- Mild steels
- High carbon and alloy steels
- Brass and copper
- Aluminium alloys
If you are unsure which material or grade suits your application, tell us how and where the bolt will be used and we will help you choose.
Made to your drawing
Every bolt we make is custom. Diameter, length, head type, thread type, thread length and finish are set by your drawing or specification. We supply parts with finishes such as nickel plating, zinc plating and black oxide, so tell us what your application needs. As with all our CNC turned components, batch sizes run from fewer than 10 pieces to more than 10,00,000.
Where our custom bolts are used
Our customers are in automotive, large equipment manufacturing, civil, plastic moulding and fabrication, among other sectors. See the industries we serve.
Matching fasteners for the same project
If your assembly also needs matching fasteners, we make stud bolts, nuts and washers. Our quality control process includes roundness checking and surface texture checking to within 0.001 mm.
Frequently asked questions
Can you make non-standard bolts?
Yes. We work to your drawing or specification, including non-standard lengths, head shapes and thread details.
What information do you need for a quote?
A drawing or specification with the diameter, length, head type, thread type and pitch, material or grade, finish and quantity. If something is missing, we will ask.
Do you make small batches?
Yes. We make batches of fewer than 10 pieces and also production runs of more than 10,00,000.
