Extended Operation In A Variety Of Work Applications The new Snap-on 3/8" Magnesium Impact Wrench (MG31) offers increased versatility in a lighterweight package.

  • An Anvil Stop Lock feature that immediately halts the spinning anvil upon trigger release, increasing safety by preventing bolts or sockets from slipping or suddenly releasing.
  • Replaceable non-slip, comfort-cushioned handle and trigger, shielding the users hand from cold, compressed air and adding comfort during use.
