The sleeves are color-coded, gray for metric sizes and red for SAE sizes, to ensure easier socket selection while also featuring stamped & ink filled sizes for the boldest, longest lasting markings. Milwaukee sockets are engineered with high strength forged steel for optimized performance in heavy-duty applications. The dual-hole design and ring groove allow for easy socket attachment and removal. Milwaukee® Shockwave Impact Duty™ lug nut wheel sockets are optimized for use with 1/2 in drive impact wrenches, drivers, ratchets, and adapters and meet ASME industry standards for thin-walled sockets.
