  • What is Automotive exhaust self-locking copper nut?

A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, stiff nut or elastic stop nut, is a nut that resists loosening under vibrations and torque. An automotive exhaust manifold copper lock nut is used in conjunction with an exhaust stud, a lock nut is just like a standard nut, but the lock nut has the added function of locking itself to the stud thread. 

  • What is Automotive exhaust self-locking copper nut for? 

A exhaust manifold is subject to high heat which is generated from the engine cylinder. The heat along with vibration from a high revving engine where nuts expand from the heat and loose. A copper lock nut is useful when mounting a manifold to engine cylinder head. 

  • The feature of Automotive exhaust self-locking copper nut.

The nut is strongly copper-plated and is therefore suitable in areas of extreme heat eg. exhaust manifolds. Suitable for temperatures from -70 to 400 degrees centigrade.

DIN14441 slit exhaust copper lock nut M6

DIN14441 slit exhaust copper lock nut M6

Size: M6~M12. The locking mechanism for this nut is based on the slit at the collar. The slit is collapsed before tightening onto the screw or bolt. As the nut is tightened onto the fastener, the slit expands, pinching the threads of the screw and locking the nut in place.
