This Cost Effective 12 Point Washer Nut has a very distinctive appearance - it has a 12-point (equivalent to double hexagonal) raised head. This design provides a 30-degree contact surface for the sleeve, so even with limited space, a larger torque can be applied.
The most obvious feature is the nut's permanently fixed pad - it can rotate freely but will not come off. This pad is wider than the nut itself, so it covers a larger area in the contact material region. Combining the 12-point head and the built-in pad makes this nut easily identifiable and the effect is very good.
This Cost Effective 12 Point Washer Nut can save you a significant amount of money as it combines two components - a gasket and an independent pad - into a pre-assembled integrated part.
This integrated design reduces inventory costs (you don't need to separately store the two items), makes the assembly process simpler, and reduces the time workers spend on the job. Yes, the initial cost of a single gasket may be slightly higher, but when you add up all the installation costs, it is usually much cheaper than using conventional gaskets along with separate pads.
This is why it is a wise cost-saving choice for large manufacturing or construction projects.

Q: Are your Cost Effective 12 Point Washer Nut reusable, or are they designed for a single installation?
A:Our regular Cost Effective 12 Point Washer Nut is usually made to be non-reusable—it’s a prevailing torque fastener. Most of the time, it has an elastic insert or a deformed thread. These parts create friction (that’s the prevailing torque) to keep the nut from coming loose because of vibration.
This deformation is almost always permanent, so you shouldn’t reuse the Cost-Effective 12 point washer nut for important jobs. If you do reuse it, it might not lock as well, and that could mess up the joint’s integrity. We always suggest using a new 12-point washer nut every time you put something together.
