Review BOEING Bolt

The Boeing NAS1104-78D and NAS1104-78L bolts are essential components in various aerospace applications, specifically designed for use in Boeing's Next-Generation 737 and 757 aircraft. These bolts are manufactured to meet the highest industry standards for quality and reliability.

The NAS1104-78D bolt is a standard, unthreaded fastener with a diameter of 0.433 inches and a length of 1.5 inches. It is made from high-strength, low-alloy steel, specifically designed for aeronautical applications. The bolt's head conforms to the NAS (National Aerospace Standard) J273 specification, ensuring a standardized fit and function. The threaded portion of the bolt adheres to the NAS B1883 specification, ensuring compatibility with standard aerospace threads. The bolt's shank is treated with a corrosion-resistant coating to protect against environmental degradation and ensure longevity.

The NAS1104-78L bolt, on the other hand, is a lockbolt, also known as a torx-head bolt or a self-locking bolt. It has the same diameter as the standard bolt but is longer, with a length of 2.5 inches. The lockbolt design provides several advantages over standard bolts. It eliminates the need for nuts and provides a secure, self-locking connection. The bolt's head conforms to the NAS J2951 specification, which features a tamper-evident, recessed torx-head design that prevents unauthorized removal. The threaded portion of the bolt adheres to the NAS B1883 specification, ensuring compatibility with standard aerospace threads. Like the standard bolt, the lockbolt's shank is treated with a corrosion-resistant coating.

Both the NAS1104-78D and NAS1104-78L bolts are designed to withstand the rigorous conditions of aerospace applications, including high loads, extreme temperatures, and exposure to corrosive environments. They are subjected to rigorous testing to ensure they meet or exceed the relevant industry standards for strength, durability, and reliability.

In summary, the Boeing NAS1104-78D and NAS1104-78L bolts are high-performance, corrosion-resistant fasteners specifically designed for use in aerospace applications. The standard bolt is a threaded fastener with a diameter of 0.433 inches and a length of 1.5 inches, while the lockbolt is a self-locking fastener with the same diameter and a length of 2.5 inches. Both bolts undergo rigorous testing to ensure they meet the highest industry standards for quality, reliability, and performance.
