NAS machine bolts are commonly used in aircraft, space shuttles, military vehicles, drones, and other high-performance applications. They are offered in different series to meet application requirements. NAS6203 through NAS6210 series include hex head, close tolerance, alloy steel, short thread, self-locking & non-locking bolts.
Sourced from quality producers, NAS6203 through NAS6210 series are offered as part of our own branded (AVIATIONEU NEW ERA) product lines. These fine-threaded, dimpled-head hex bolts have a minimum tensile strength of 160,000 psi and a minimum shear strength of 95,000 psi. Thread length is consistent within each diameter (1103/6203 series have a shorter thread), and grips are available in 1/16” increments beginning at 1/16”. Used in applications where a premium-quality, high strength bolt is necessary. They come in different nominal diameters: NAS6203: 3/16 in. (0.1875"), NAS6204: 1/4 in. (0.25"), NAS6205: 5/16 in. (0.3125"), NAS6206: 3/8 in. (0.375"), NAS6208: 1/2 in. (0.500"), NAS6210: 5/8 in. (0.625").
NAS6208 series shear hexagon head bolts with a 1/2-20" thread supercede NAS1108 high strength bolts. Their shearing feature is used to minimize damage to critical components of the application. They are made from alloy steel with cadmium or chromium finishes and offered in different grips and lengths in inches with undrilled or drilled head and/or shank. They are sold in pieces.

"C" for chromium plated bolts
"L" for self-locking bolts
Grip Dash Number indicating grip in .0625 increments. The following letters after this number indicate:
"D"/"H" drilled thread/ drilled head
