Rivet nuts are often used in daily life, but most people think that they must be tightened very tightly. But today R-Best Fasteners will tell you that this is not the case. Let’s take a look.
There are many cases of screwing rivet nuts and screws in life. Some people think that the tightening the better, but in some cases, the tightening is too tight and it "does not help."
When handling water pipes and tires, rivet nuts and screws should not be tightened too tightly. In toilet wash basins, kitchen sinks, etc., flexible hoses are installed between the faucet and the cold and hot water pipes (usually made of PVC). The rivet nut between the fixed hose and the PVC water pipe should not be tightened too tightly, otherwise the hose and water pipe may be damaged or cracked.
If the rivet nut is tightened too tightly, the interface will be rusted, which is not conducive to disassembly. It is recommended that when screwing the nut, screw it by hand first, and then use a spanner to twist it half a turn to one turn after it reaches the end. When installing car tires, the screws should not be tightened too tightly, otherwise the screws may be deformed and affect the fixing effect.
On the same tire, the tightness of each screw must be even, and no individual screws can be tightened very tightly. Otherwise, it will affect the tire's driving. In severe cases, the screws may be broken due to uneven force. When screwing the tires, if you do it yourself, you must tighten them one by one in a diagonal order. Each screw must be divided into several times and gradually increase the force. The screws are "suffering". Don't screw them all at once.
