Guaranteed load:
The guaranteed load is the axial load that the nut must withstand without creating a thread trip or a sign of cracking the nut wall. It is an absolute value with no maximum or minimum. In general, when the applied load reaches 95% of the thread trip load, the thread deformation will affect the thread fit.

Cone guaranteed load:
The tapered guaranteed load is tested when the nut is placed on a hardened tapered washer with a taper angle of 120o. The nut must withstand and there should be no axial tripping or axial loading that would result in cracking of the nut wall. This test is used to determine the effect of surface defects (forging cracks or cracks) on the performance of the nut.

hardness:
Hardness is a measure of resistance to wear and external force. Similarly, the hardness of the nut is also specified in the standard three hardness values ​​of Rockwell, Brinell and Vickers.

Other testing items:
Surface defects, etc.

Common Nails

Common Nails:
