CTA Manufacturing Corp. offers the Torque Limiting Ratchet Wrench, No. 8940, featuring a 3/8" square drive. The wrench installs and removes oil filter housing caps with 25Nm torque specifications. An internal torque limiting device prevents over-tightening of caps, which has been a source of service problems. This tool also features an 11-1/2" (290mm) length with soft-grip handle for optimal use in oil changing environments.
