1-1/2" Drive 6-Point SAE 3-3/16" Flank Drive Shallow Impact Socket

• 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.

• Chrome sockets are heat treated to optimize non-impact torque application (too brittle for impact use and are not the safe choice).

• 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.
