Description
The Mishimoto High-Torque Worm Gear Clamp (MMCLAMP-WG-20HT) is a stainless steel worm gear clamp engineered to secure hoses, couplers, and pipes with an outside diameter between 0.43 and 0.79 inches (11mm-20mm). Sold in a pack of ten, this Mishimoto Fabrication clamp features a silver, plain-finish stainless steel band paired with a worm gear tightening mechanism built to hold a dependable seal in demanding underhood environments.
Built for fabrication and hose-clamping projects across the engine bay, this high-torque worm gear clamp resists corrosion longer than standard zinc-plated hardware thanks to its full stainless steel construction, including a steel spring for consistent clamping pressure. The worm gear design allows for quick, controlled tightening, and Mishimoto recommends a tightening torque of 35 in-lbs (4 NM) to help achieve a secure, leak-resistant seal without over-tightening. Reusable and finished with a premium-grade stainless steel band 0.31 inches wide, these clamps are designed to handle applications ranging from vacuum lines to intake pipes, and this clamp line is also offered with an optional wear-resistant titanium nitride gold coating for unique engine bay styling.
Vehicle Applications
As a Fabrication-category part, this Mishimoto worm gear clamp is not limited to a single make or model.

Whether you’re building custom intake piping, securing vacuum lines, or replacing a worn factory-style clamp on a hose within this diameter range, this clamp provides a versatile clamping solution across a wide range of applications.
