Have a good day.I am received your Drawing.
The post specification is ok.But the Bolt,nut,and washer is differ from our common.
So please check the attachment,it is our drawing about the Bolt,nut,and washer.
1.The Bolt is M6X1.25P,so change the 6.7 to 6.0
2.The nut 7.5 is too thin,hard to screw.common size is more than 9.0.
3.The washer thickness 1.7 is not our common size,we also produce 1.5 or 2.0.If 1.7 is necessary,need make a new model,the price is higher.
Ok,that is all,Looking forward your reply.
Hope have a chance to cooperation with you.
