Rod Bolt Stretch Gauge with Billet Body & Thumb Hold

We highly recommend using a stretch gauge when installing rod bolts and other fasteners, where it is possible to measure the length of the fastener. It is the most accurate way of measuring preload of any bolt. Simply follow manufacturer's instructions, or use the chart in the ARP catalog for ARP rod bolts.When using a stretch gauge it's best to measure the fastener prior to starting and monitor overall length during installation. When the bolt has stretched a specified amount, the correct preload or clamping force has been applied. We recommend that you maintain a chart of all rod bolts and make a note of the fastener length prior to installation and after any disassembly. If there is a permanent increase of .0005? or more in length, there is a deformation and the bolt should be replaced.
