4-3/16" SAE Flank Drive® 6-point shallow impact socket with 1" drive

Characteristics
• Snap-on® impact sockets are heat-treated to optimize impact life with a lower hardness than manual sockets and are able to withstand repeated cyclic loads from impact wrenches.
• The chrome-plated sockets are heat-treated to optimize the application of torque without impact (too brittle for impact use and are not the safe option).
• Snap-on uses a proprietary blend of special alloy steel that provides long service life and great strength.
• Our FLANK DRIVE® wrench system delivers up to 20% more turning power without slipping or rounding while exceeding ANSI® performance standards.
