The Two Way Serrated Clamp (FD), also known as the Form Thread Worm Drive Clamp, is a medium-duty clamp designed for high mechanical load applications. Its unique feature is the two-way serrated design, with threads on both surfaces of the band, ensuring a better circular grip and preventing seepage, making it suitable for relatively hard hoses.
Jolly Serrated Worm Drive Clamps are versatile and used in various industries, including: ● Automotive applications ● Filter systems ● Domestic uses ● Industrial machinery ● Agricultural equipment
These clamps are made using high quality materials that meet AISI or equivalent global standards. They are available in the SS300 grade series and SS316 grade, with the latter being ideal for marine applications due to its superior corrosion resistance.
The clamp operates on the principle of worm gear action, where the cleanly formed threads and serrations on the band ensure secure tightening or loosening. This mechanism offers a strong and reliable grip for the application.
