Overview

Using a Rod Bolt Stretch Gauge when installing rod bolts and other fasteners is highly recommended whenever it is possible to measure the length of the bolt after torquing. Verifying with a stretch gauge is the most accurate way to determine the correct pre-load in the bolt. ARP recommends you maintain a chart of all rod bolts, and copy down the length of the fastener prior to and after installation. If there is a permanent increase of .001 in length or more, or if there is deformation, the bolt should be replaced immediately.
