Nuts and bolts are small parts that play a role in fastening and connecting when fixing tools. They are easy to install, integral, without washers, and easy to disassemble. The materials generally used as nuts are mainly carbon steel, stainless steel, copper, alloys, etc. Among the many types of nuts, butterfly nuts are greatly convenient to use because of their unique appearance - the butterfly-shaped design with a protruding head. So, what is the role of this small butterfly nut? The editor of Gongpin No. 1 will show you the use of butterfly nuts.

Unlike the materials used for general nuts, the main plastic material of butterfly screws is nylon 6/6. This special material gives butterfly nuts a unique application field. Butterfly bolts have excellent characteristics such as insulation, non-magnetic, corrosion resistance, beauty, and never rust. The modified engineering plastics have the same strength and impact resistance as metals. The plastic screws we often call, commonly known as nylon screws, have added 30% glass fiber. Its mechanical properties are far better than ordinary nylon. The materials used for butterfly plastic bolts are becoming more and more diversified, the performance is constantly improving, and the application field is becoming wider and wider.

Generally known bolts refer to screws with larger diameters. According to this statement, screws are much smaller in diameter than bolts. Stud bolts have no head, and some are called studs. Both ends of the butterfly nut are threaded, but the middle is not threaded, and the middle is a bare rod. Stud bolts are used on large equipment such as reducer racks. In actual use, the external load will vibrate and the influence of temperature will cause the friction to decrease. Over time, the threaded connection will loosen and fail. Therefore, it is necessary to do a good job of maintaining the stud bolts in normal times. Stud bolts or anchor bolts will have problems under the action of long-term mechanical friction. When problems occur, the engine oil pan must be removed and the use of the engine bearings must be carefully checked. Check whether the gap between the bearings is too large. If the gap is too large, it must be replaced in time. When replacing the stud bolts, the connecting rod bolts must also be replaced. If some large equipment such as nail making machines are found to be not very stable or have abnormal noises during normal operation, they must be stopped and checked in time to avoid greater problems.
