Mishimoto T-bolt clamps are a great solution for projects that need more clamping force than a standard worm gear clamp can provide. Built from the same stainless steel as our worm gear clamps, these T-bolt clamps are as durable as they are strong. This 3.15" - 3.39" (80mm - 86mm) T-bolt design provides superior clamping power while the included locking nut keeps the clamp tight against any vibration. Available in a wide range of sizes, these clamps are an excellent choice for a variety of applications. Like all Mishimoto clamps, this 3.15" - 3.39" (80mm - 86mm) T-bolt clamp is backed by our Mishimoto Lifetime Warranty.
