The Astro Pneumatic 78810 is a 10-piece torque limiting extension set designed for accurately torquing wheel nuts to manufacturer-specified values using a 1/2" drive impact wrench. Each 8" extension bar is engineered to limit torque output at a precise threshold, eliminating the risk of over-torquing and preventing wheel and stud damage caused by unchecked impact wrenches. Constructed from Chrome Molybdenum (Cr-Mo) steel, the bars deliver exceptional strength and durability under demanding shop conditions. The matte black finish and color-coded collars provide fast, at-a-glance identification of the correct torque setting without the need for any maintenance or recalibration.
