This is a purpose built rod bolt stretch indicator, weighing less than 6 oz. This is the best way of determining correct rod/cap fastener torque. It's the lightest indicator on the market and a proprietary design. The reason for the light weight: it stays on the bolt better, and at any angle. No part in this unit is off the shelf. Easy to use, and accurate to .0005". There is a cheaper tool available from one of our competitors, but it lacks the ball end, which makes our tool repeatably accurate. Our gauge is also superior if you test them both, as we have.
