Rod Bolt Stretch GaugeBillet Style With Dial IndicatorBrand: ARPPart Number: AR100-9942Description: We highly recommend using astretch gauge when installing rod bolts and other fas teners where it is possible to measure the length of the boltafter tightening. It is the most accurate way to determinethe correct pre-load in the rod bolt. Simply follow manufacturer’s instructions.Measure the fastener prior to starting, and monitor overall length during installation. When the bolt has stretched the specified amount, the correct preload, or torque, has been applied. We recommendyou 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 .0005˝ in length or more, or if there is deformation, the bolt should be replaced immediately. Don’t chance it! ARP offers a highly accurate stretch gauge with a dial indicator that reads in increments of .0005˝. Features extra heavy springs for consistent repetition. Comes with a heavy-duty, insulated plastic carrying case for protection. A “must” for any serious engine builder. Show more
