Our SHOCKWAVE Impact Duty™ 1" Drive 1-1/8" Thin Wall Extra Deep 6 Point Socket features the boldest, longest-lasting markings. The stamped and ink-filled size markings enable you to select the right socket every time throughout the life of the socket. The 6-point extra deep sockets are engineered with high-strength forged steel for optimized performance in high stress applications, and a non-slip hex geometry prevents fastener rounding. The thin-walled and extra-deep construction allows the socket to fit in tight access, deep recesses. The dual-hole design and ring groove allow for easy socket attachment and removal. Our Lifetime Guarantee backs all MILWAUKEE® SHOCKWAVE Impact Duty™ Sockets and meets ASME industry standards.
