ANYTIME THERE IS A STUD LEFT I POUND A 12 POINT SOCKET (ONLY THING THEY'RE GOOD FOR) ON IT AND RATCHET IT OFF.
OTHER TIMES I MAKE A STRAIGHT SLOT WITH MY DREMEL DISC AND USE A FLAT TIP SCREW DRIVER.
WHEN ALL ELSE FAILS I DRILL AND TAP. COBALT BITS WORK GREAT BUT ARE HELLA SPENDY.
SORRY BOUT THE CAPS.
