The t-bolt gains its name from its flat, straight head, which makes it resemble the letter “t”. Longer than an average bolt, the upper shaft of a t-bolt is unthreaded. With hand adjustment or machine adjustment possible, t-bolts offer versatility as well as precision, making them a good choice for convenience both on the production line and in the field. As a result of this flexibility, combined with the t-bolt’s considerable strength, t-bolts are widely used throughout the aviation production process.
