@ramonamarshall20014: Regular socket gets stuck. A pass-through socket keeps going. The hollow design lets long bolts and threaded rods pass straight through instead of bottoming out, so you can keep turning without switching tools. With metric sizes from 10-24mm, this set is handy for automotive, machinery, and garage repairs. #PassThroughSocket #SocketSet #MechamcTools #AutomotiveTools #RatchetTools
