Star Insert Bits for Tamper Resistant are engineered for maximum durability and long life with impact drivers. These star insert bits are designed with precision tip geometry so they fit fasteners more precisely, which reduces stripping. The precision geometry of these bit delivers superior fitment, and reduce cam-out. The hole in the center in each star insert bit causes it to be tamper-resistant. It can be used in automobiles, repairs, engines, motorcycles, interiors, dashboards, computers, cable boxes, toys, appliances, and consumer electronics.
