Calcheck if you want an easy way to cut off those bolts and have access to a sawsall (reciprocating saw) go to Home Depot (or anywhere they sell Milwaukee tools/accessories and look for a white rectangular shaped metal cutting blade called “The Torch”. I had to trim the length of about 100 3/8” diameter Red Head concrete anchors and this blade went thru them like “butta” and that was with just a cheap 18 volt Ryobi Battery powered sawsall. One blade…100 easy cuts…well worth the money…
