Notes from the standard
- Part number: MS20601, the sleeve material letters in place of the dash (AD 2117 aluminum alloy, B 5056 aluminum alloy, M Monel; P after the material letter for cadmium plate), the diameter in 32nds, W for the serrated stem and the grip number: MS20601AD5W5.
- Grip number 1 covers grips up to .062 in. Length is the maximum length of the sleeve.
- Head angle 100° ±1° (aluminum alloy), ±1-1/2° (Monel). Head edge .002 - .006 (aluminum alloy), .002 - .015 (Monel).
- 5056 aluminum alloy rivets are identified by an orange color, color number 32246.
- .001 in shank diameter increase permissible within .100 in of the base of the head.
- Serrated stem rivets (series W) are universally, functionally and dimensionally interchangeable with knob stem rivets (series K) with proper tooling. Knob stem rivets (series K) and rivets with no stem letter were inactive for design after 21 March 1962.
- Interchangeability: inactive MS20605 numbers AD4E, AD5E, AD6E, AD8E, B4E, B5E, B6E, B8E, M4E, M5E, M6E and M8E are replaced by MS20601 AD4W, AD5W, AD6W, AD8W, B4W, B5W, B6W, B8W, M4W, M5W, M6W and M8W; ML_E and MP_E by MP_W of the same diameter. Corresponding grip numbers are directly interchangeable. AD3E, B3E, ML3E, MP3E and M3E have no substitute.
- Qualified products: QPL-7885. Design usage limitations: MS33522.
- Approved data governs. Use the fastener the SRM, drawing or IPC calls for.
