About these measurements: Las medidas publicadas por Vincent Bach (y por la mayoría de fabricantes) son nominales y orientativas, no valores de ingeniería de precisión. Bach publica diámetros redondeados al 0.05mm más cercano, lo que explica que modelos distintos compartan el mismo valor publicado (p.ej. 1X, 1B, 1C, 1-1/4C, 1-1/2B y 1-1/2C todos figuran como 17.00mm en el manual oficial). Esta práctica es habitual en el sector: los fabricantes redondean o aproximan las medidas publicadas para proteger sus diseños y evitar copias exactas. Las medidas reales pueden diferir en 0.05-0.15mm entre modelos que comparten el mismo valor nominal. Para el motor de equivalencias, estos modelos se tratan como distintos por su copa, profundidad y backbore, no solo por el diámetro.
