Profile: Defiance Integrated Technologies (DIT) operates two manufacturing divisions. Defiance Stamping Company & Pro Shear Corporation are ISO/TS certified facilities servicing automotive, HD truck & trailer, industrial, and multiple off-road industries. Our services include metal stamping, laser cutting, metal fabrication, axle nuts, and engineered products. Axle nuts are produced as a four component system, and shipped together as a single unit which includes the thrust washer, spring, lock ring, and nut. When installed, the interlocking internal key prevents rotation, and the outward pressure from the spring on the lock ring engages the matching set of teeth on the lock ring & nut, to keep everything securely in place.
