The Precision Brand C-H series collared screw worm gear clamp has a series 300 stainless steel band and housing, and a zinc-plated steel screw that is collared to help reduce the risk of hose damage from screwdriver slippage. A worm gear mechanism adjusts the clamp’s diameter to precisely apply sealing pressure. The band’s 9/16” width provides a greater sealing area than clamps of smaller width. The band, housing and screw are made of stainless steel that conforms to the Society of Automotive Engineers (SAE) 300 series standard and provides resistance to corrosion in marine environments. The slotted, 5/16” hex-head screw allows installation using a blade screwdriver, nut driver, or socket wrench. The screw is made of carbon steel that is zinc-plated for resistance to rust.
Hose clamps attach hoses to fittings to prevent flow leakage. They come in a variety of designs and distribute uniform pressure over the circumference of hoses to bind them to fittings. Hose clamps are suitable for a large number of industries, and commonly used in industrial, electronic, and automotive applications.
