Just as a brake pivot bolt is usually a button head socket cap screw whether its head is domed or conical. Not to be too critical - but it is the HEAD shape that is critical. As all of the illustrations that Jeff published shows - they are available in any threads. Can you explain to me exactly why you believe that the THREAD is what makes an internal wrenching head? You're sounding more and more like Frank every day. He doesn't even understand that the difference between a taper head screw and a cap screw is.. You're joining his club I see. I have to admit I had never heard the term 'internal wrenching bolt' until you wrote that. Given the high profile disasters from counterfeit fasteners sold to the Air Force and the required specification for same (material, fit/finish tolerances, plating, hardness etc) I could well imagine that USAF simply made up a distinctive head shape to keep stray hardware out of their system, keep engine mounting bolts separate from brake system bolts and so on. I don't know that, but it's not unreasonable. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 That tapered head was made to cover the majority of the washer. Cap head bolts support less of the washer. Wouldn't that depend on the size of the washer? https://images.amain.com/images/larg....jpg?width=475 Note that stem bolts also come in a conical configuration, too. https://tinyurl.com/yxo9pvyb -- Jay Beattie |
