The KTC Tools Nepros Bit Sockets are available in Phillips, flat (1/4" sq. only), hexagonal and T-type Torx. Their bit portions feature a titanium nitride coating, ensuring a higher wear resistance than traditional tools, the company says. The socket portions have a chrome coating, highly resistant to peeling, corrosion and wear abrasion, while contributing to a degree of heft in addition to a beautiful finish. An added feature of the 3/8” sq. line are rubber rings that increase ease of use when turning the bits by hand, or pulling them out.
