casper50 Posted November 30, 2018 Report Share Posted November 30, 2018 Trying to google this bolt/screw to buy some for a rebuild. No luck. Anyone know what it's called? That would greatly improve my odds for finding some. Thanks. Quote Link to comment Share on other sites More sharing options...
TodFitch Posted November 30, 2018 Report Share Posted November 30, 2018 My guess, emphasize guess: Hex headed self-tapping metal screw. Its got a hexagonal head From reading the parts books, my impression is that a machine screw has threads all the way to the head whilst a bolt is not threaded all the way up. The threaded portion looks designed for sheet metal but does not have the self-drilling feature of some. Quote Link to comment Share on other sites More sharing options...
casper50 Posted November 30, 2018 Author Report Share Posted November 30, 2018 Thanks Tod. That helped. https://www.amazon.com/Steel-Sheet-Plated-Thread-Length/dp/B00GI52OJ6/ref=sr_1_4?s=industrial&ie=UTF8&qid=1543613836&sr=1-4&refinements=p_n_feature_two_browse-bin%3A2292868011%2Cp_n_feature_fourteen_browse-bin%3A17910846011 Quote Link to comment Share on other sites More sharing options...
DonaldSmith Posted November 30, 2018 Report Share Posted November 30, 2018 Yep, hex-head sheet metal screw. I bought a few at the local Ace Hardware for my snow thrower, to match what was on there. Different diameters and lengths. For screwing the plastic shroud to sheet metal. Holes already drilled in the sheet metal,so self-drilling not necessary.

Todd B Posted December 1, 2018 Report Share Posted December 1, 2018 Looks like a lag screw to me. I don’t think it’s an original dodge screw. 1 Quote Link to comment Share on other sites More sharing options...
Todd B Posted December 1, 2018 Report Share Posted December 1, 2018 1/4” x 3/4”. Possibly 5/16” x 3/4” Quote Link to comment Share on other sites More sharing options...
casper50 Posted December 1, 2018 Author Report Share Posted December 1, 2018 It's for a 55 Pontiac. Original fastener for battery tray to inner fender. Quote Link to comment Share on other sites More sharing options...
Los_Control Posted December 1, 2018 Report Share Posted December 1, 2018 (edited) Must be a name for them, my dodge truck is held together by the same bolts. The toe boards use this bolt with a metal clip style nut. The spring clip attaches to one piece of metal, in this case the floor of the cab, then set the toe board down and the bolt screws in to the clip on the cab floor. Hope that makes sense I do not have a loose clip without opening up my sealed bolt pouches. I am missing several of these bolt and clips myself, have not searched online for them. My inner fenders use this method along with the center hood section. I think they are a very common bolt for dodges. I also think the clip style nuts are handy for the toe boards where you only can reach one side at a time. When I put my inner fenders back on, I will replace with a common nut/bolt. They will last longer and give me 10 extra bolts/clips to use elsewhere. A quick google search for body bolts should get what we need Edited December 1, 2018 by Los_Control Quote Link to comment Share on other sites More sharing options...

Todd B Posted December 1, 2018 Report Share Posted December 1, 2018 The screw Casper showed is a lag screw I would say is used for wood not steel. The Dodge screw los pictured has a different square thread to fit the clips. Two completely different screws pictured. 1 Quote Link to comment Share on other sites More sharing options...
casper50 Posted December 1, 2018 Author Report Share Posted December 1, 2018 (edited) the one pictured is the same as the other 9 in both front fenders of the 55 Pontiac. I have 3 that the heads are rusted so bad as to not be hex anymore. I believe lag screws have a sharper point to dig into wood. Whereas this is blunted for metal.

Plymouthy Adams Posted December 1, 2018 Report Share Posted December 1, 2018 (edited) That is a very coarse thread sheet metal screw..and yes, very close in appearance to a typical lag screw used in wood working. These were popular for grille and gravel shield fastening on these old cars and can often be found in other common uses about the body. Often these are used in conjunction with a J-nut. They are typically #14 body size...though can be found in 5/16. There are other similar screws in this fashion but more than not with a finer thread pitch, often with a washer/displacement built into the head. You can find these in coarse, fine, head style, metal composite and various lengths and body sizes in the online Restoration Specialties catalog...sometimes you can get lucky at the hardware store but for the most part the basic fly by night stuff they carry is grade 2 and so cheap it is just worth the effort to bring home to use.
