Inquiry (采购产品): Product Inquiry I'm searching for a plastic hex drive 7/16-20 plug. However, this is used to hold back a spring for two buttons in a Dive Computer, rather than as a plug. I should be thin (approx 4 threads) and the hex drive should pass completely through the part to allow water to freley flow from under the button cavity. **** Hidden Message ***** David Kenyon 07960 Company: Hamilton Research, Ltd.
