Snap-on 7 pc 3/8" Drive 6-Point SAE Flank Drive® Semi-Deep Impact Socket Set (3/8-3/4")

• Includes IMFS12A-IMFS24 (3/8-3/4") in a magnetic storage tray

• Snap-on® impact sockets are heat-treated to optimize impact service life with a lower hardness than hand sockets and are able to withstand repeated cycling loads of impact wrenches

• Snap-on uses a proprietary blend of special alloy socket steel that provides long life and great strength

• Flank Drive® wrenching system delivers up to 20% more turning power without slipping or rounding while exceeding ANSI® performance standards

• The broach depth of our impact sockets will start to thread the nut onto the stud; competitive sockets have a deeper hex, meaning the user needs to start the nut by hand

• Square drive side hole works with ball- or pin-type retention

• Industrial, black-oxide, finish helps protect against corrosion
