V-Band Clamp InstallationUpdated 2 years ago

Thank you for your purchase! Please take a moment to review the following information before installing your new V-Band Clamp.

Our V-Band Clamps, sold individually or as part of an assembly, are supplied with two types of nuts — a lock nut (installed on the clamp) and a non-locking nut. Metal lock nuts are NOT meant for mock-up or testing. Metal lock nuts will begin to “lock” onto the bolt as soon as it is threaded on. Metal lock nuts should NOT be removed frequently. Attempting to thread, remove, and rethread a metal lock nut may cause damage to the T-Bolt section of the clamp. If you intend to use our clamps during the mock-up process please use the standard finished hex nut (non-locking style). Please note that an impact wrench should never be used to install a V-Band Clamp.

Note: Ace Race Parts is not responsible for damage caused to our clamps due to the use of the metal lock nut during mock-up, testing, or removal. Ace Race Parts is not responsible for damage caused to our clamps due the use of an impact wrench.
