I had a old set of replacement grips and no screw. No problem, I got a screw from another set and went down to the local 95 year old hardware store that has always had everything I needed. Not this time...we looked through every bin and compartment and drawer in there and couldn't find a match. I spent the entire saturday goiing to every store that sold screws and never found a match. On Monday I went to a Fastener Supply house, they claimed to have every screw, nail , nut, bolt and special fasteners you needed....Guess what they didn't have...a freaking grip screw to match them threads. I don't know what size/pitch them screws are but you can't find one in Baton Rouge , Louisiana....so do not loose it!
