The Jolly Heavy Duty Stainless Steel Worm Drive Clamp is designed for heavy-duty, high-torque applications in industries such as automotive, marine, oil & gas, and engine applications. It is suitable for high-pressure, vibration-resistant, and demanding installations.
The clamp features a strong and rigid two-piece housing that can withstand installation torques of up to 8.5 Nm and ultimate torques of up to 11.5 Nm. This design ensures maximum strength and stability, making it ideal for high-torque applications like automotive and earth-moving equipment.
The clamp operates using the principle of a worm gear action. This means that the gearing action between clean punched perforations and the thread of the hex head screw enables precise tightening and loosening of the clamp on the application.
The liner prevents direct contact between the perforations in the clamp and the hose. This design feature avoids hose biting, which can occur when the clamp is tightened at high installation torque, thus protecting the hose from damage.
The clamp is made with high-quality materials that meet AISI or equivalent global standards. It is available in SS300 grade, SS316 grade (suitable for marine applications), and SS200 grade series. The screw options include SS300 series, SS410 grade, or plated carbon steel with Hexavalent and Trivalent Zinc plating for enhanced durability.
Yes, the Jolly Heavy Duty Worm Drive Clamp is available in SS316 grade, which is highly resistant to corrosion and is specifically suited for marine applications where exposure to saltwater and harsh conditions is a concern.
These clamps are ideal for a variety of high-torque, high-pressure applications, including automotive, engine applications, earth-moving equipment, marine, and oil & gas sectors. Their robust construction makes them versatile across different industries requiring secure and durable hose connections.
