Brass Inserts

We are one of the leading manufacturers and exporters of Brass Inserts from India. We have been supplying Brass Inserts to the world market for many decades. Based in Jamnagar, Gujarat, our facility specializes in both blind and through Brass Inserts with no minimum order quantity, ensuring deep‐groove knurling and precision threads that comply with international Go / No‑Go standards. Whether you require Diamond, Straight, or Unidirectional Knurling, our inserts deliver maximum pull‑out resistance, tight inner‑diameter tolerances, and flawless fit in plastics, composites, and soft metals.


Product Overview

Brass Inserts are threaded bushings pressed or molded into softer materials to provide durable, reusable screw threads. Manufactured from high‑conductivity Brass alloys, these inserts offer excellent corrosion resistance, electrical conductivity, and mechanical strength. Our Inserts prevent thread stripping, improve product longevity, and are ideal for applications in electronics, automotive interiors, furniture, medical devices, and consumer goods.

Manufacturing Process

Our multi‑stage process ensures consistent quality:

  1. Cold Heading: Brass slugs are formed into pre‑shaped inserts.

  2. Knurling: Diamond, Straight, or Unidirectional patterns are rolled for grip.

  3. Thread Rolling: Threads are formed under pressure to achieve Go / No‑Go compliance.

  4. Deburring & Cleaning: Ultrasonic cleaning removes swarf; parts are rinsed and dried.

  5. Quality Inspection: SPC/SQC system records Cpk values, max/min measurements, and thread‑gage verification for every batch.

    Yes—both blind and through Brass Inserts are available with no MOQ.

  2. What materials can they be pressed into?
    Suitable for thermoplastics (ABS, PC), composites, soft alloys, and wood.

  3. Do you support custom knurl patterns?
    Yes—besides Diamond, Straight, and Unidirectional, bespoke patterns can be developed.

  4. Are inserts RoHS compliant?
    All materials and processes meet RoHS and REACH regulations.

  5. How are inserts delivered?
    Supplied in polybags or loose bulk cartons; custom packaging on request.

  6. Do you provide test reports?
    Each lot ships with SPC/SQC reports, including Cpk and dimension data.

  7. Can you machine inserts after production?
    We offer secondary operations such as plating, passivation, or polishing.

  8. What thread sizes are supported?
    From M2 to M12 metric; UNF, UNC, BSP, and NPT also available.

  9. How do I install blind versus through inserts?
    Blind inserts are set with a heat or ultrasonic press; through inserts use expansion or knurl grip.

  10. Can you ship globally?
    Yes—we export via sea, air, and courier to over 50 countries.
