NODIADAU:
Mae dimensiynau mewn milimetrau.
SYLWCH: (1) Mae uchder y gyfran uchel yn hafal i ddyfnder dimensiwn rhigolE, ond nid yw yn ddarostyngedig i'r goddefiadau ar gyferE. Gellir defnyddio cyfuchlin wyneb llawn.
Goddefgarwch Dimensiwn
E (dyfnder): +0.41, −0.00
F (lled): ±0.20
P (diamedr traw): ±0.13
R (radiws ar y gwaelod): +0.8, −0.0 ar gyfer R Llai na neu hafal i 1.5; ±0.8 ar gyfer R > 1.5

NODIADAU:
Mae dimensiynau mewn milimetrau.
(1) Nid yw'r trwch fflans lleiaf yn cynnwys y trwch wyneb uchel.
(2) Mae'r dimensiwn hwn ar gyfer pen mawr y canolbwynt, a all fod yn syth neu'n dapro.
(3) Ar gyfer weldio a bevel.
(4) Nid yw hyd y bollt gre yn cynnwys uchder y pwyntiau.
(5) Gellir pennu hyd bolltau nas dangosir yn y tabl yn unol ag Atodiad D Anorfodol.
