Notices

Disclaimer

We publish size tables, grades and photographs so that a buyer can recognise what we supply. They are descriptive, not a specification you should design against.

Last updated 27 October 2026

Chakraborty Overseas, a sole proprietorship registered in India · Registered address: 30/2 Shib Chandra Chatterjee Street, Belur Bazar, Howrah 711202, West Bengal, India · IEC, GSTIN and EEPC RCMC available on request

1. Published information is indicative

Size ranges, grades, property classes, finishes and weights on this Site describe what we ordinarily export. They are collected from manufacturers' catalogues and from published standards, and they change as our sourcing changes.

Do not design, quote or order against a page on this Site. The binding description of any goods is the one on the quotation or proforma invoice we issue to you, together with the mill test certificate supplied with the consignment.

2. We are a merchant exporter

Chakraborty Overseas sources from verified Indian manufacturing partners. We do not operate forging, machining, heat treatment, plating or testing facilities of our own.

Manufacturing certifications, including ISO 9001 quality management and the testing accreditations behind a mill test certificate, are held by those partners, not by us. Where we list them, we list them as supplier certifications. The registrations we hold in our own name — IEC, GSTIN and our EEPC Registration-cum-Membership Certificate (RCMC) — are set out on the Certifications page.

3. Product photography

Photographs illustrate the type, head form and finish of a fastener. They are taken from our manufacturing partners' catalogue material and are not photographs of the consignment you will receive.

Appearance varies with size, manufacturing unit, coating batch and standard. Where finish or marking matters to you, ask for a sample or a pre-dispatch photograph of the actual production.

4. References to standards

ISO, DIN, ASTM, ANSI, BS, BSW, UNC and IS designations belong to the organisations that issue them. We use them to identify the specification a fastener is made to.

A reference on this Site is not a claim that we are accredited, licensed, certified or endorsed by any standards body, nor a substitute for reading the standard itself. Standards are revised; check the edition that applies to your project.

5. Not engineering advice

Nothing on this Site is engineering, structural or safety advice. Choosing the grade, class, coating, length and torque for a joint — particularly in structural, pressure, marine or safety-critical work — is a decision for a qualified engineer with the full context of the application.

We are glad to discuss what is available and what is commonly used, and we will tell you when a question is outside what a supplier can properly answer.

6. Outside links and third parties

Links from this Site to other services are offered for convenience. We do not control them, do not endorse them, and are not responsible for their content or their handling of your information.

7. Impersonation and payment fraud

Our only email domain is the one shown at exports@chakrabortyoverseas.com, and our published telephone and WhatsApp number is +91 98316 47114.

Exporters are a standing target for invoice-redirection fraud. We will never announce a change of bank account by email alone. If you receive any message that appears to come from us asking you to pay into a different account, stop and confirm it by telephone on the number published here before transferring anything.

8. No warranty for the site

This Site is provided for information, as it stands. To the extent the law allows, we accept no liability for loss arising from reliance on it. Our obligations for goods we actually supply are set out in the Terms of Sale.

Questions on this document

Write to us before you order rather than after. We would rather answer a clause now than argue about it against a bill of lading later.

Send us a specification

Size, grade, standard, finish and quantity is enough to start. If something is missing we will ask rather than assume.
