You don’t always have to tap internal threads when installing machine screws. Some screws are designed to tap their own threads when driven into objects. Known as self-tapping screws, they save time and energy by eliminating the need for tapping. … Read More
Jet engines are the backbone of the commercial aviation industry. Statistics show that they power over nine in 10 commercial airliners. When compared to propeller engines, such as turboprops, jet engines are typically faster, quieter and more efficient at high … Read More
While the exact number varies, research shows that there are over 100,000 commercial flights globally per day. Commercial flights, of course, are operated by businesses known as airlines. Airlines sell flight services for scheduled routes to the general public. There … Read More
Pilots must constantly monitor climb rate. Expressed in feet per minute (FPM), it represents the speed at which an airplane ascends or descends. A positive climb rate indicates the airplane is ascending and gaining altitude. A negative climb rate indicates … Read More
Set screws are commonly used to secure pulleys and gears to shafts. Also known as grub screws, they are characterized by a headless design. Set screws still have a threaded body like standard bolts. Rather than a traditional flared head, … Read More
