High strength galvanized double head bolts

The commonly known Bolt refers to a Screw with a larger diameter, and according to this statement, a screw has a much smaller diameter compared to a bolt. Double headed bolts do not have a head, and some are called double headed studs. Both ends of the double head bolt are threaded, with no thread in the middle and a smooth rod in the middle. Double headed bolts are used on large equipment such as speed reduction racks. In practical application, the external load will experience vibration combined with the influence of temperature, resulting in reduced friction force. Over time, the threaded connection will become loose and fail. So it is necessary to do a good job in the maintenance of the double head bolts during normal times. Double headed bolts or anchor bolts can have problems under long-term mechanical friction. When problems occur, the engine oil pan should be removed, and the use of the engine bearing shells should be carefully checked to see if the gap between the bearing shells is too large. If the gap is too large, it should be replaced in a timely manner. When replacing the double head bolts, also replace the connecting rod bolts. If some large equipment, such as nail making machines, find that the engine is not running stably or makes abnormal noises during normal operation, they should also be stopped and checked in a timely manner to avoid larger problems.SA193 Double Head Boltsc,Galvanized Double Head Bolts,High Strength Double Head Bolts,High strength galvanized double head bolts
