   "SAE 45° flare (the tube end is flared to 45°, the nut pulls it against a male cone). The size name is the TUBE OD; the dash number is the tube OD in sixteenths of an inch (-4 = 1/4 in tube). Threads are straight UNF: 1/8 in tube 5/16-24, 3/16 in 3/8-24, 1/4 in 7/16-20, 5/16 in 1/2-20, 3/8 in 5/8-18, 1/2 in 3/4-16, 5/8 in 7/8-14, 3/4 in 1-1/16-14, 7/8 in 1-1/4-12. These match Parker's catalogue for every size and the thread list on McMaster-Carr's 45° flared fittings page. The governing standards are SAE J512 and J513; their text is paywalled and was not read.",
   "Do not mix with 37° (AN / JIC) or with compression nuts: 1/4 in flare is 7/16-20 (this page), 1/4 in compression is 7/16-24, and the 37° AN -4 is also 7/16-20 with a different seat. See 'an-jic-37-degree-flare-fittings' for 37°. A 7/16-20 nut cross-threads on a 7/16-24 fitting, and 45° and 37° seats leak against each other.",

SC Fastening's catalogue pages give an independent set for a short rod nut (A = length, hex): its A and hex equal Parker's short nut for 1/8, 3/16, 1/4, 5/16 in (hex 0.37 vs 3/8 and so on is rounding); its long forged nut differs from Parker's long nut (1/4 in hex 0.62 vs 9/16, 3/8 in A 1.06 vs l 1.31), so both are shown rather than merged. Dash sizes follow Parker's part numbers (41FS-2 to 41FS-14).",
   "Files (17): hex envelopes of Parker's short nut (9 sizes) and long nut (8 sizes): hex across flats c, length l, a through hole at the tube OD. No internal thread, no 45° seat, no tube relief, because none is published; the thread size is in the file name only. The dimension the nut screws onto (male thread, 45° cone, flare diameter) is not published in a readable table, so no fitting body is drawn.",
