Jerry Roberts Posted August 2, 2015 Report Share Posted August 2, 2015 I found odd diameter fine thread stud sizes on the Pilot House studs that mount the stainless trim horizontal bars on the front of a pilot house truck . The common 1/4 inch fine thread nuts are too big and a 10 gauge fine nut is too small . Has anyone else come across this problem ? I first though that the diameter had been decreased by rust but there are some existing nuts that fit well . Anyone know the oddball size ?

Dodgeb4ya Posted August 2, 2015 Report Share Posted August 2, 2015 They used 12 ga fasteners. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted August 2, 2015 Report Share Posted August 2, 2015 you can still find the 12 gauge fasteners...just not as common as it once was..I ordered a box of 100 self sealing 10-24 nuts online...check out e-bay or Restoration Specialties or about any well heeled hardware store...

Jerry Roberts Posted August 5, 2015 Author Report Share Posted August 5, 2015 (edited) I found the 12 gauge bolts at Orchard Supply Hardware . The size is 12 - 24 . I ran a 12-24 tap through the new nuts so that they fit my existing threads better . They have about 70 stores in California and Oregon .

Harbison Posted October 6, 2015 Report Share Posted October 6, 2015 Does anyone have a picture of these? None of my grille pieces were attached when I got the truck. Searching for 12 gauge fasteners and not coming up with anything. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted October 6, 2015 Report Share Posted October 6, 2015 (edited) 12 sizes are still available..just not as common...you want specialty hardware..go to a specialty hardware supplier...you local hardware store may or may not stock this...e-bay however will get you all you want 12 guage is in reference to metal thickness not screw size...it also refers to a caliber of shotgun shell...ask for #12 machine screw or nut/washer as needed odd size ...not....uncommon today..yes..in a recent project here at the house I drilled and tapped some 380 holes and utilized the stock modern application and factory supplied #12 machine screw.

Dave72dt Posted October 6, 2015 Report Share Posted October 6, 2015 12-28 and 12-32 bolts are still common as well as # 12,10,8, 6 screws in varying lengths, varying head types. # 6,8, and 10 series bolts are still out there as well. Try a different hardware store. I've been sourcing them from a local True Value store, straight off the shelf. Quote Link to comment Share on other sites More sharing options...
Harbison Posted October 6, 2015 Report Share Posted October 6, 2015 So just a #12 nut? I thought maybe they were some sort of special fastener or something. Like I said I don't have anything to go by. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted October 6, 2015 Report Share Posted October 6, 2015 ok..so I get it you do not have any threaded stud available for you to look at and check for thread pitch? is your trim piece void of any mounting hardware be it bolt or clip and you would like to know or see a picture of what is needed...?

Dave72dt Posted October 6, 2015 Report Share Posted October 6, 2015 2 different pitch sizes for a # 12. Take a sample with you to the hardware store or the part itself. None of the grille trim pieces are so large that you can't walk in with one and they'll never mistake it for coming off there one of there shelves.

Harbison Posted October 6, 2015 Report Share Posted October 6, 2015 Plymouthy Adams, I have all the studs. I was under the impression that dodge used some special clip like some of the other truck manufacturers did. Dave72dt, I'll carry one of them into Ace and see what they have. Thanks for all the responses. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted October 6, 2015 Report Share Posted October 6, 2015 often in the manner of fastening clip to the body the nut is a special cupped style and often filled with a slight proud amount of sealant to aid in rust prevention..

JBNeal Posted October 7, 2015 Report Share Posted October 7, 2015 here are some close-ups of a '48 grille bar mounting stud nut & lock washer combo...the lock washers are slightly concaved with the outer teeth on the sheet metal and the inner teeth against the nut. The studs are #12-28, the lock washers could probably be replaced with a helical spring lock washer Quote Link to comment Share on other sites More sharing options...
Harbison Posted October 7, 2015 Report Share Posted October 7, 2015 JBNeal, thanks for the pictures. That really helps. I looked at the local Ace Hardware and found plenty of #10 but no #12. I'll keep hunting. Quote Link to comment Share on other sites More sharing options...
ggdad1951 Posted October 7, 2015 Report Share Posted October 7, 2015 those lock washers are "special" and I got a bunch of them from Grainger. Reusing them is 50% at best as they tend to crack. Quote Link to comment Share on other sites More sharing options...
