Hex Bolts

Hex bolts are manufactured with Hexagonal Heads and machine threads for use with a matching nut or in a tapped hole. These are also known as Hex Cap Screws or Machine Bolts. The bolts are manufactured fully threaded and partially threaded as per the international standards or specific applications. Fully Threaded Bolts are popular by name of Hex Screws while partially threaded bolts are termed as Hex Bolts.

Darshan Automotive Industries has a strong potential and known for making Hex Bolts. The blanks are forged on precise automatic bolt formers and headers and then trimmed to across flat as per the requirements. After this process, secondary operations, if required, are performed. Then these bolts are threaded by thread rolling process using toughened rolling dies and controlled with the help of calibrated thread guages.

Darshan Automotive Industries has a wide capacity to develop and manufacture Hex Bolts and Hex Screws that are not confirming to International Standards such as DIN, ASTM,  BS, ANSI, IS and ISO etc but are important for specific use of such Fasteners. The applications of our speciality fasteners products are wide and varied in various industrial sectors like Electronics, Electrical, Automotive, Telecom, Engineering and Railways etc.

If you need for a standard bolts or customised as per your design or specifications, we are capable to produce them best suitable to your applications and satisfaction. Dedicated to continual improvements, 100% on-time delivery and zero defects, Darshan Automotive Industries is committed to meeting and exceeding its customer’s expectations in quality and delivery. With a wide range of cold forging machineries, Darshan Automotive Industries is uniquely qualified to manufacture a wide range of Hex Bolts.

Our total quality system has helped us to maintain a standardization of measurement, reduce variation in operations to guage and gage to part variation. We are experienced in screws parts, gaining excellent reputation worldwide and shipping the products to suppliers all over the world. Thus, these encourage us to continuously enhance our operating procedures and keep up to date with the latest SOP standards. Our principle is to maintain top quality at a reasonable price, while satisfying our customers at the same time, providing fast and efficient service.

We manufacture special fasteners in various head shapes and drives. The most common are Hexagonal Head and Hex Flange Head Bolts
