1" SAE Flank Drive® 6-point semi-deep impact socket with 3/8" 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.
• Snap-on uses a proprietary blend of special alloy steel for dies that provides long life and great strength
• The Flank Drive® wrench system delivers up to 20% more turning power without slipping or rounding, while exceeding ANSI® performance standards
• The square hole on the drive side operates with ball or pin type retention
• The scraping depth of our impact sockets will begin to thread the nut onto the bolt; competing sockets have a deeper hex, meaning the user must strip the nut by hand. The industrial black oxide finish helps protect against corrosion.
