Original WWII era North American Aviation Brass Terminal Bolts/Studs (p/n: 5B5-1) with #10-32 Threads at one end and 1/4”-28 threads at the other end. They are individually wrapped and preserved with grease. 1st photo is of the un-wrapped and the 2nd photo is of them wrapped and greased. North American Aviation is famous for building the P-51 Mustang fighters, B-25 Bombers, AT-6 “Texan” Trainers and other WWII era aircraft where these studs were utilized. See copy of original specs page in one of the photos. Specs page shows both 5B5 and 5B5-1. The 5B5-1’s have #10-32 thread at one end and 1/4-28 at the other end. I have both types listed. 15 each 5B1-1 with #10-32 threads at one end and 1/4-28 threads at the other end. Even though item is in New Surplus condition, buyer is responsible to make sure that this part will work for their application as there is no warranty or guarantee expressed or implied. Thank You |
