Just dropped $350 on a new torque wrench for head bolts and it was worth every penny
Had to do head gaskets on a 6.7 Powerstroke last week and my old clicker wrench was way out of spec. Bought a Snap-on TechAngle and it made the whole job feel way more solid, no guesswork on the angle turns. Anyone else have a go-to tool that seemed pricey but totally saved a job?
