smith8833 Posted June 25, 2015 Share Posted June 25, 2015 Anyone ever use these? U-drive screws or Hammer screws! Quote Link to comment Share on other sites More sharing options...
Michael Cochran Posted June 25, 2015 Share Posted June 25, 2015 I used them at work assembling store shelving back in 2009. Never used them with any kind of smithing. Quote Link to comment Share on other sites More sharing options...
Quarry Dog Posted June 25, 2015 Share Posted June 25, 2015 Weren't/Aren't these used to fasten nomenclature/manufacturer plates to the frame of industrial machinery? Like for pieces that don't have sheet metal on the frame to pop-rivet to. I know I've seen something like it on machinery that has a solid cast iron frame, and some smaller stuff milled out of solid steel. Quote Link to comment Share on other sites More sharing options...
Jim Coke Posted June 25, 2015 Share Posted June 25, 2015 Greetings Smith,Another name for them is Drive Rivets.. They work great for attaching sheet metal wings on dragons or humming birds. Commonly used for attaching machinery tags..Forge on and make beautiful thingsJim Quote Link to comment Share on other sites More sharing options...
Frosty Posted June 25, 2015 Share Posted June 25, 2015 Would that make them Drivets Jim? Do you know how solid they hold? I'll bet if driven into hot steel, interference fit fashion, they'd break before pulling.Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Quarry Dog Posted June 25, 2015 Share Posted June 25, 2015 I have seen more than a few on old military ISO shelters (kinda like a shipping container, but with doorways, electrical, lighting, a/c, storage, equip, etc., etc.) that had nameplates with broken off "Drivets". I've also seen a few oldish mills/lathes with only a couple of them on the nomenclature plates. In almost all cases not involving extreme corrosion in the hole, the head had broken off.

smith8833 Posted June 25, 2015 Author Share Posted June 25, 2015 Thank for the info guys!! They are reported to be case hardened and need to be driven into a correct size hole! I am attaching a forged edge to thin wall square tubing! These would look like rivet heads instead of using bolts or screws! I may have to get some and just try it!!

Michael Cochran Posted June 25, 2015 Share Posted June 25, 2015 (edited) Let me look and see if I still have some. If I do I'd be willing to send some for you to try if the size will work. Edited June 25, 2015 by M Cochran Quote Link to comment Share on other sites More sharing options...
WL smith Posted June 26, 2015 Share Posted June 26, 2015 I have used them a lot. They work great. To remove just take a chisel to the side and drive them reverse direction. Very useful rivet for blind applications. Quote Link to comment Share on other sites More sharing options...
smith8833 Posted July 10, 2015 Author Share Posted July 10, 2015 WL smith, did you use them in thick stock? I want to use them on hollow square tube! Sorry for the late response been out of town! Quote Link to comment Share on other sites More sharing options...
WL smith Posted July 13, 2015 Share Posted July 13, 2015 Yes just follow the guide line dimensions For the threads and remember a cold chisel will remove them when driven backwards against normal rotation. Very use full For blind riveted looking attachments. Quote Link to comment Share on other sites More sharing options...
