Draw Tite Weight Distribution Hitch

I'm looking for a Draw Tite weight distribution hitch bolt 1/2-13 x 3 1/2. I haven't been able to find one. I can buy a kit from Amazon for $80.00 but I thought I would try here first.

Tom

Hi Tom,

That hitch bolt you are looking for, is that a full threaded set screw with a square head and used on the snap up brackets or the dual cam frame plates? And if so, how many do you need?

Does it look like this? https://www.mcmaster.com/91410A726/

Let me know, I may have some options for you. The one above I linked, Not sure I would buy that one. I need to find a better grade of steel, just trying to understand what bolts you need first.

Hope this helps.

John

Hi John,

Thank you for your question. It is a full threaded set screw with a hex head but a square head is just as good. Yes it does look like the one in the link. Thank you for your help.

With kind regards,
Tom

Hi Tom,

Trying to help, but I also do not want to accidently get you into an issue not knowing how the fastener is being used.

You mentioned, yours has a "hex head" and is a "set screw", that combo of hex head and setscrew is not common. It is not be impossible, but not common, and I have not seen it used with a hex head on Reese or Drawtite hitch.

Which part on the hitch is this fastener used on? And did you buy this hitch new or was it used? Meaning someone may have substituted something. They so make 1/2"-13 full threaded bolts 3 1/2" long, but they are bolts and not setscrews. Most times, they are used in different applications.

The 1/2"-13 x 3 1/2" long. square head set screw is common on the Drawtite and Reese chain snapup brackets or the HP dual cam frame mounting plates.

Here is a pic of the snapup with the setscrew.


The DC frame plate, you can see it in this pic


Sorry for this being this hard, but don't want to suggest a wrong strength fastener in the wrong application. Set screws can be made from case hardened steel and made to ASTM B18.6.2 standards for compressive loads "only". They have a tip on them to pinch hold something from moving, like a cup point etc. They are not rated for tension holding, only compression holding.

If you want a "bolt" they are rated in both compressive and tension loads and strength rated by grade. Grade 2, 5 and 8 are the most common in US standards. These come in different head configurations. These are very common to get and most have some type of plating on them, but they do not have case hardened cup points like a set screw.

Here are options for a setscrew, assuming this is what you need. The issue is to get the zinc coating on them so they do not rust.

I found a Reese hardware kit cheaper then Amazon with the "set screws" in it cheaper then. This may be what you found. They are plated at least.
https://www.etrailer.com/Accessories...ese/66014.html

Both the McMaster Carr, Fastenal and MSC have 3 1/2" lg set screws in plain steel, not coated. Fastenal does not offer zinc in 3 1/2" length. They do in 3" or 4" if that would work for you. These are made to that ASTM B18.6.2 compressive loads standard.

https://www.mcmaster.com/1%2f2-13-sq...ivalent~0-500/

https://www.fastenal.com/product/fas...egation=Length

MSC has them, but they called out a grade 2 fastener which is not very strong, they to not list the ASTM rating. And they are not plated either.
https://www.mscdirect.com/product/details/67391045

The 3 places above are some of the many industrial supply places I have bought from over the years that sell fasteners. They are cheaper, just you have to add freight, but are not zinc coated. Or paint/treat them once installed to not rust

You may try at a "good" old fashion hardware store, or a fastener supply house in your area.

Hope this helps

John

PS. If you want "bolts" they are a easier to find due to being more popular in the 1/2"-13 length.

Hi John,

Thank you for getting back to me and for all of your work. I have to apologize for giving you the incorrect information. This is actually a bolt. I have attached a picture of it. I'm sorry to put you through so much trouble. If they are common I should be able to locate one. Thank you for all of your help John.

With kind regards,
Tom

Thanks Tom, a pic is worth a million words. You have one of the really older Drawtite snapup brackets. I have not seen one of them in a while and forgot they may have the bolt.

Now armed with the pic. Start hunting for a DORMAN 960-425D - Hex Bolt - Grade 8 - 1/2 in.-13 x 2-1/2 in. Dorman is the brand, used a lot in automotive aftermarket https://www.dormanproducts.com/p-46668-960-425.aspx

See here. https://shop.advanceautoparts.com/p/...nid=11910845-P

Finding the fully threaded part will be uncommon. Standard bolt threads are 2x the diameter + 1/4" for bolts under 6" long" or in this case, only 1 1/4" long. I just found it on the Dorman site as they have some of this more special stuff.

You can ask around for "1/2"-13 x 3 1/2" fully threaded, hex head bolt, grade 8" if you do not have an auto parts store that sells Dorman. Buying on line, the freight will be more then the bolt.

Hope this helps

John

Hi John,

Again, thank you ever so much for you help. This is great information! I will follow up on it. I tried the hardware stores in my area including a couple of bolt specialty stores to no avail. I appreciate the links and path you have given me. I also appreciate your helping so many of us. Take care.

With kind regards,
Tom
