Threaded inserts will be tough to screw into place. When the thread first grabs, there’s a tendency for the insert to tip sideways and enter at an angle. Whereas particular instruments can be found to assist, a easy substitute is available. Discover a bolt that’s not less than 2 in. lengthy and suits the insert, lock two nuts close to the top, and thread the tip of the bolt into the insert. Then use a ratchet to drive the insert into place. The lengthy bolt makes it straightforward to maintain the insert plumb, and the ratchet does the remainder.
