ボルト フランジ- Bolt Flange
 
Flange bolts with a underlined 8 mark:
92101-ZZXXX-0Y
ZZ is the size, 05, 06, 08, 10, 12 for M5, M6, M8, M10, M12 
XXX is the length in millimeter
Y is the plating, A for white zinc, B for chrome*, G for black, H for chromate**, J for brown bronze like platting.
 
*The chrome version may not have any mark on the head.
** Chromate is not really yellow. It looks like white zinc with a yellowish tint!
 
You will receive each bolt in a separate sealed plastic bag. OEM stuff is always a safe choice for quality.
