The end of the handle features a rotating end cap that allows the tool to spin in your palm, helping to minimize discomfort during long wrench sessions. Plus, the tip size is laser etched in not one - but the THREE different spots on the handle to help simplify identification.
ProTek R/C "TruTorque SL" screwdrivers also feature precision cut tool steel tips that provide an exceptional fit with the fastener, and feature a bronze colored finish that not only looks good, but also helps to protect the steel from corrosion. When it comes to high quality products that are backed by incredible customer support, ProTek R/C has you covered with the products you need to keep your rig ready for action, no matter what.
