Inquiry (采购产品): Fastener question To whom it may concern, I am currently an engineering student at Lehigh University and involved in a project that requires type "C" fasteners. We are designing a collapsible ski pole and need different sizes for the diameter of the entire ring of the fastener, however we could not find that information on the data sheet provided. Also we are only looking to buy three of each size fastener and a total of 9. Please send us all the information possible. Thanks for your time Sincerely, Andrew Crape Joel Hockman Lehigh University anc6@lehigh.edu **** Hidden Message ***** Andrew crape 562 Hillside Ave Bethlehem, PA 18015 USA Company: Lehigh Student Phone: 203 7676648 E-mail: anc6@lehigh.edu **** Hidden Message ***** anc6@lehigh.edu
