TEKTON S2 steel bits are press-fit into the socket for a straight， permanent connection that can't loosen over time. The star-shaped Torx bits have 6-lobes machined to precise tolerances for an exact， high-torque fit that resists camming out. The set includes both Torx and Tamper-Resistant Torx bit sockets， stored in a sturdy， well-marked case. Die-stamped markings are permanently impressed into the steel and cant wear off. They're designed with large， clear size numbers that are easy to read even in low light settings. The bit socket's polished chrome plating protects against corrosion and wipes clean to a mirror finish. The deepest parts of the socket well， where nickel and chrome layers cannot be deposited in sufficient thickness， are protected with an additional thin layer of clear coat， rather than conventionally-used silver paint， to prevent rust. Bit sockets come organized in a well-marked， sturdy case.
