About this deal
Four grooved detents allow secure attachment to the socket handle; socket will engage the ratchet regardless of its position. Concentric broaching evenly distributes the torque load; uniform wall thickness on box end for added safety and durability. Snap-on Flank Drive sockets move the contact away from the corners with a radius for better flat-to-flat contact and up to 20% more turning power.

Double chamfer at both the drive and wrench openings provide easy fastener and square drive engagement.
