Make servicing and replacing TPMS sensors and other small scale precision tasts easier with the STEELMAN 98029 2-Piece 40 in-lb Red TPMS Torque Driver and Tommy Bar Set. This 6.7-inch long hand tool kit features a fixed, 40 in-lb setting on the driver to eliminate torque setting errors that can lead to over-tightening of sensors. Made from lightweight machined and red anodized aluminum, the driver has a knurled texture rings across its surface for additional drip. The screwdriver style tool has a 1/4-inch drive tip with a detent ball for use with any 1/4-inch drive metric or SAE socket. The driver's internal mechanism gives slightly and creates a click upon reaching the preset inch-pound torque level to prevent overtightening. When working in tight or awkward spaces where it can be difficult to apply the full 40 in-lb of torque, the included tommy bar can be inserted into the hole on the handle to provide increased leverage. Useable in a wide range of uses from weapon smithing and assembly, automotive maintenance, and electronics repair.
