ebinmaine 67,277 #1 Posted September 29, 2019 . I got these little clamps in a bucket stuff this morning. The end of the screw is cupped which may indicate a set screw? There is a marking on each one that says 3/8. Just curious to know what they are or if there is something else that they would be put into. Share this post Link to post Share on other sites
Stormin 9,981 #2 Posted September 29, 2019 (edited) With you saying the end of the screw is cupped, Eric, makes me think of something for making holes. Edited September 29, 2019 by Stormin Share this post Link to post Share on other sites
ACman 7,618 #3 Posted September 29, 2019 (edited) Are the bottoms of the clamp threaded for 3/8” too ? If so I’d say a beam clamp used to hang things from using 3/8” rod . Guess there’s different sizes too . We used 3/8” for hanging duct , gas lines , ect. off beams in commercial buildings. https://www.grainger.com/product/ANVIL-C-Clamp-Beam-Clamp-4HYF4 Just ( different types of beam clamps images ) and you may find something that you could use and didn’t even know it existed .

Can you photo the bottom of the clamps? 1 Share this post Link to post Share on other sites

oliver2-44 9,689 #6 Posted September 29, 2019 I think those are some type of rivet clamps. I have some that we’re in my dads aircraft stuff. Not exactly sure how they were used Share this post Link to post Share on other sites

Kenneth R Cluley 515 #9 Posted September 29, 2019 Definitely beam clamps for hanging pipe tubing a/c units etc from structural steel or metal buildings. 1 Share this post Link to post Share on other sites
ACman 7,618 #10 Posted September 29, 2019 (edited) This side should be threaded too ? Edited September 29, 2019 by ACman 1 Share this post Link to post Share on other sites
formariz 11,987 #11 Posted September 29, 2019 13 minutes ago, ACman said: Is this side threaded too ? Should be threaded making it a vertical load beam clamp. They are extremely use full for other than the intended applications. I have used them on a deck adjuster that kept slipping out of adjustment to clamp it solid and similar stuff. 2 Share this post Link to post Share on other sites

peter lena 8,582 #13 Posted September 29, 2019 installed , MILES OF PIPING with those, always adding process lines as demand required, used them on a lot of the hopp 2, miller beer concentrate , we were using Pyrex clear glass lines to verify flow points . why is miller beer clear ? we used to make the synthetic concentrate for their beer, a natural hop would spoil in clear glass thats why its a dark color to protect the beer. pete Share this post Link to post Share on other sites
JCM 9,130 #14 Posted September 29, 2019 In the Plumbing & Heating Trade in Massachusetts those were known as 3/8'' side beam clamps to be used in conjunction with threaded rod and either A band,F&M Rings or Clevis type pipe or tubing Hangers, I am sure they have different names depending on where you hail from.

ebinmaine 67,277 #15 Posted September 30, 2019 I'm not in the Workshop anymore so I can't take a picture of that other hole but it is NOT threaded. It is in fact, larger than the threaded end. 1 Share this post Link to post Share on other sites
Stormin 9,981 #16 Posted September 30, 2019 I wonder if someone has drilled it out for some reason? Share this post Link to post Share on other sites
