1/2" Drive 15mm Thick-Wall Impact Socket, No. S6700

The Snap-on 1/2" Drive 15 mm Thick-Wall Impact Socket, No. S6700, is designed for high-torque, multi-pass diesel head bolt installation, including applications like Ford 6.7 L Powerstroke engines, eliminating the need for hand-starting by engaging the fastener sooner than deeper sockets. Its thicker wall and heat-treated design help prevent premature failure under repeated torque cycles. According to Snap-on, the Flank Drive system delivers up to 25 percent more turning power, reduces rounding, and exceeds ANSI standards. A short profile improves access in tight engine bays, with a square drive side hole supporting secure retention during use.
