Maintenance Tips & Tricks – 2000 – #19

Loosening bolts
Problem: Loosening hard-to-unscrew bolts and screws is a challenging chore. Is there an easy way to get the stuck bolts moving?

Solution: Place a properly sized drive punch in the center of the bolt head (or cup if SHCS bolt) and use hard tapping with a hammer. The “shock” created unsettles the stubborn bolt and removal is almost certain.
