The BOLT held the blade onto the mower deck just fine. I used an impact wrench to install the bolt, so it would not come off when I mowed, thereby increasing my chances of not having a fatal accident. The whole repair took 72 seconds, which included a torque wrench test of 20 foot pounds of torque. Good Bolt. Make sure you start the bolt install with a couple of right hand turns to seat the bolt correctly before applying the impact wrench to tighten.
