Notes from the standard
- Shear collars: C = 2024 aluminum, E = carbon steel, G = 2024 aluminum alloy, AG = 2219 aluminum. Tension collars: no letter = 2024 aluminum, R = carbon steel, AT = 2219 aluminum alloy. The last two digits are the nominal size (05 = .164, 06 = .190, 08 = .250).
- Shear collars of nominal size .250 (08): the listing prints two total-length ranges, .220-.236 and .230-.250, without saying which part numbers each applies to; the length cells of those four rows are left blank.
- The listing shows separate type C and type E collar drawings; their dimensions are not legible and are not given here.
- Approved data governs. Use the fastener the SRM, drawing or IPC calls for.
