T-bolt hose clamp A T-bolt hose clamp is a robust, high-strength clamp designed for high-pressure applications, where a worm-drive clamp just won't cut it. It's especially common in industrial, automotive, and turbocharged engine setups. Design :A solid band with a T-bolt and lock nut. Tightened using a socket or wrench. Materials : Usually stainless steel (bands and hardware) for durability and corrosion resistance. Size Range :Typically larger than worm clamps – ideal for thick hoses (like intercooler, coolant, or exhaust hoses). Torque Range :Higher than worm clamps – allows for a tight, uniform seal. Often torque-rated. Adjustability : Somewhat less flexible than worm clamps—each size fits a narrower range.
