I don't know....but if you email Albert (go to his site for contact info).....he will probably respond in reasonable time. He has been very helpful and quick to respond to questions I have had in the past.
Robofet, the e-mail I sent to Albert using the e-mail address on the Von website (albertvonn@aol.com)got returned with the message "----- The following addresses had permanent fatal errors -----". Do you have another e-mail address for Albert ? Thanks.
FYI the 8mm thread comes in 2 different pitches: 1 or 1.25; for metric threads that is the dimension from crest to crest or valley to valley, the english equivalents would be .0393 inch or .0492 inch respectively. The thread designation therefore would be M8x1 or M8x1.25 Hope this helps.
