WORM DRIVE CLAMP Material: Made from stainless steel (SS), they are resistant to corrosion and rust, making them ideal for outdoor, marine, or high-humidity environments. Worm Gear Mechanism: The "worm drive" part refers to the threaded screw mechanism that tightens or loosens the clamp. Turning the screw pulls the band tighter around the hose, ensuring a secure fit. Adjustable: These clamps are adjustable to fit a range of hose sizes, making them versatile for different applications. Durability: Due to the stainless steel construction, they are durable and long-lasting, providing strong resistance against rust, corrosion, and wear.
