<p>Thank you for your purchase! Please take a moment to review the following information before installing your new V-Band Clamp.</p><h4 id="avoid-over-tightening"><strong>Avoid Over-Tightening</strong></h4><p>V-Band Clamps seal by drawing the two flanges together inside the clamp&apos;s V-shaped channel &#x2014; they are <strong>not</strong> meant to be cranked down like a typical bolted flange. <strong>Over-tightening is the most common cause of clamp failure.</strong> Applying excessive torque can stretch or snap the T-Bolt, strip the threads, or distort the band so that it no longer seals correctly. Our clamps require very little torque to seat and seal. When in doubt, tighten to the low end of the torque specification, confirm the seal, and stop &#x2014; do not keep tightening past spec in an attempt to &#x201C;make sure.&#x201D;</p><h4 id="nut-types"><strong>Nut Types</strong></h4><p>Our V-Band Clamps, sold individually or as part of an assembly, are supplied with two types of nuts &#x2014; a lock nut (installed on the clamp) and a non-locking nut. <strong>Metal lock nuts are NOT meant for mock-up or testing.</strong> Metal lock nuts will begin to &#x201C;lock&#x201D; 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. <strong>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.</strong></p><p>Note: Ace Race Parts is not responsible for damage caused to our clamps due to over-tightening or exceeding the published torque specifications. 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 to the use of an impact wrench.</p><table style="width: 100%;"><thead><tr><th style="text-align: center;"><strong>FASTENER TYPE</strong></th><th style="text-align: center;"><strong>PURPOSE</strong></th><th style="text-align: center;"><strong>MATERIAL TYPE</strong></th><th style="text-align: center;"><strong>LOCKING TYPE</strong></th><th style="text-align: center;"><strong>NOTE</strong></th></tr></thead><tbody><tr><td style="width: 20%; text-align: center; vertical-align: middle;">Hex Lock Nut</td><td style="width: 20%; text-align: center; vertical-align: middle;">Installation (Long Term Applications)</td><td style="width: 20%; text-align: center; vertical-align: middle;">Zinc Plated Steel</td><td style="width: 20%; text-align: center; vertical-align: middle;">Yes</td><td style="width: 20%; text-align: center; vertical-align: middle;">Installed on clamp</td></tr><tr><td style="width: 20%; text-align: center; vertical-align: middle;">Finished Hex Nut</td><td style="width: 20%; text-align: center; vertical-align: middle;">Mock-up &amp; Testing</td><td style="width: 20%; text-align: center; vertical-align: middle;">Zinc Plated Steel</td><td style="width: 20%; text-align: center; vertical-align: middle;">No</td><td style="width: 20%; text-align: center; vertical-align: middle;">Supplied in a small ziplock bag</td></tr></tbody></table><p>Ace Race Parts provides as many non-locking hex nuts as clamps ordered (example: if 10 clamps are ordered, 10 non-locking hex nuts will be provided).</p><h4 id="torque-specifications"><strong>Torque Specifications</strong></h4><p>Please note that the lock nuts supplied with our V-Band Clamps do not require a great amount of torque to be secured on the clamp.
