Ken-Tool introduces its #30116 five-piece impact 1/2-inch drive deep twist socket set. These sockets easily remove rounded, damaged or corroded nuts, bolts, pipe nipples and studs. The Thinwall socket is designed to reach in areas where a standard impact socket might not give the clearance needed. Sockets are 1/2-inch drive. Sizes are: 19mm (3/4-inch), 13/16-inch, 7/8, 15/16-inch and one inch. Made in the USA.
