SAE J429 BOLTS- Gofynion mecanyddol a materol ar gyfer caewyr edau allanol
Mae safon SAE J429 yn cwmpasu'r gofynion mecanyddol a materol ar gyfer bolltau dur cyfres modfedd, sgriwiau, stydiau, semau, ac U-bolltau a ddefnyddir mewn diwydiannau modurol a diwydiannau cysylltiedig mewn meintiau hyd at 1-1/2 yn gynhwysol.
Dylai gofynion dimensiwn edau ddilyn ASME B18.2.1 Sgwâr, Hex, Trwm, Hex, a Bolltau Pen Askew a Hex, Hex Trwm, Fflange Hex, Pen Llafog, a Sgriwiau Lad （Cyfres Fodfedd）, ASME B18.18.1M - Arolygu ac Ansawdd Sicrwydd ar gyfer Caewyr Pwrpas Cyffredinol
