\"quarter-turn<\/figure>\n<\/div>\n\n\n

When most people think of fasteners used in the aerospace industry, they envision traditional fasteners. Modern airplanes, however, are manufactured using a variety of fasteners. In addition to traditional threaded fasteners like screws and bolts, many airplanes now feature quarter-turn fasteners. How do quarter-turn fasteners differ from traditional threaded fasteners exactly?<\/p>\n\n\n\n

Function<\/h2>\n\n\n\n

Quarter-turn fasteners work differently than traditional threaded fasteners. As the name suggests, they require a “quarter-of-the-way” turn to install. Turning them clockwise by 90 degrees will lock them in place. Quarter-turn fasteners also feature a spring mechanism to apply tension and prevent accidental release.<\/p>\n\n\n\n

Ease of Removal<\/h2>\n\n\n\n

Quarter-turn fasteners are easier to remove than traditional threaded fasteners. Both traditional threaded fasteners and quarter-turn fasteners can be removed by turning them counterclockwise. Quarter-turn fasteners, through, only require a 90-degree counterclockwise turn, whereas traditional threaded fasteners require multiple<\/em> 360-degree revolutions. Because they are so easy to remove, quarter-turn fasteners are commonly used to fasten panels that require frequent removal, such as aircraft maintenance panels.<\/p>\n\n\n\n

Protection From Over-Tightening<\/h2>\n\n\n\n

You don’t have to worry about accidentally stripping threads or damaging components when installing quarter-turn fasteners. All quarter-turn fasteners have a built-in mechanism that limits their rotation. Once you turn them 90 degrees — either clockwise or counterclockwise — you won’t be able to turn them further. Traditional threaded fasteners, on the other hand, are susceptible to over-tightening because they lack such limits.<\/p>\n\n\n\n

Load-Bearing Capacity<\/h2>\n\n\n\n

They may require more time and effort to install, but traditional threaded fasteners excel in high load-bearing applications. When properly torqued, for instance, a heavy-duty bolt can withstand extreme tension and vibrations. Quarter-turn fasteners aren’t as effective at withstanding loads, which is why they are typically used to secure lightweight objects like maintenance panels. <\/p>\n\n\n\n

Cost<\/h2>\n\n\n\n

You can expect to pay more for quarter-turn fasteners than traditional threaded fasteners. They have a specialized design with a stud and a built-in spring. Traditional threaded fasteners, in comparison, have a more basic design consisting of a narrow piece of material with exterior threads.<\/p>\n\n\n\n

In Conclusion<\/h2>\n\n\n\n

While they are both used to join two or more objects, quarter-turn fasteners and traditional threaded fasteners aren’t the same. Quarter-turn fasteners save time, prevent over-tightening and make routine maintenance more efficient. Traditional threaded fasteners, while slower to install and remove, provide the strength and load-bearing capacity needed for critical structural connections. Hopefully, this gives you a better understanding of the differences between quarter-turn fasteners and traditional threaded fasteners.<\/p>\n","protected":false},"excerpt":{"rendered":"
