The Role Of Stanley Spiralock Fasteners In Modern Aerospace Engineering
Rivets, stud welds, blind rivet nuts and threaded fasteners have long been an essential part of the aerospace industry. When fastening parts together securely and efficiently, designers have always looked for solutions that guarantee a solid and reliable bond without the added weight that would come with chunkier nuts and bolts. That’s why rivets and similar fasteners have always been the go to option for aircraft designers.
How Spiralock Works
The innovative wedge ramp allows the male fastener to spin freely against the female thread until such a point that a clamp load is applied. The standard male thread is then drawn tightly against the wedge ramp to create a continuous line of contact against the whole length of thread engagement. The greater the clamp load, the more the wedge ramp will push against the sides from all directions, which means there is no radial clearance and the fastener can not come loose, even under intense vibration.
The Benefits Of Spiralock For Aerospace Design
Spiralock offers exceptional resistance to vibration loosening thanks to the unique 30° wedge ramp design. This means Spiralock fasteners can withstand high vibrations without loosening, making them ideal for aircraft design.
In addition, the improved joint integrity distributes the load more evenly, creating a stronger and more reliable joint. There is also the fact of their consistent reusability. Spiralock fasteners can be reused multiple times without losing performance, helping to keep costs down and reduce carbon footprint.
Using the Spiralock design, it eliminates the need for secondary locking devices. That’s because the inherent locking mechanism of Spiralock fasteners means there is no need for additional parts like lock nuts or washers. There is also reduced galling, which means there is less friction between the screw and the fastener, minimising wear and tear.
Reliability Is Key
Stanley Spiralock fasteners are critical in aerospace applications where high reliability is key. This is not an industry where anything can be left to chance and designers and manufacturers are always looking for the highest possible level of reliability and strength. This includes engine components exposed to extreme conditions, structural connections vital to aircraft integrity and avionics systems where precision is essential. The fact so many are choosing Stanley Spiralock is an indicator of how much of an impact this fastener is having.
