We can see many types of fasteners in our daily lives, and blind rivet nut is also a kind of fasteners. So what are the misunderstandings in the use of blind rivet nut?
There are impurities such as rust, scale, iron filings, sand particles in the threads of bolts, nuts, or screw holes, or there are impurities such as burrs, mud, and sand on the joint surface of the coupling parts, which have not been removed before assembly. When tightening the bolts, due to impurities The blocking effect is that the surface is tightened very tightly, and the torque value meets the requirements, but in fact, the coupling is not compressed; also, there is another situation, due to the supporting effect of impurities such as sludge and scale in the screw hole, Although the bolt torque complies with the regulations, the workpiece is not tightened. Under such false solidity, vibration, load shock, and temperature changes often cause the bolts to loosen quickly.
The above is a misunderstanding of using blind rivet nut false solid snails. Of course, countersunk head rivet nut will also have misunderstandings. www.khfastener.com
