Square head bolts & nuts | Smokstak® Antique Engine Community*

Does anyone know where I can buy square head bolts & nuts with out having to pay a hundred dollar minimum order or having to purchase them buying each size by the bulk box of 50 or 100 count. Gets a little expensive that way. I live in Florida so it would probably have to be mail order.

Any help would be great!

Thank you... Smaller Square nuts can be found at most any hardware in those drawers. As far as Square head bolts, Some "Fastenall" fastener supplier will sell you a few at a time.

Another guy who sells them which I found at the Wauseon, OH Threasures Renunion is:
Fairview Farm Supply & Parts
:
Delta, OH

He has different sizes and caters to people restoring old farm equipment.

He may be able to help you. John,

I went into an Ace Hardware and they had a bunch of different sizes of square nuts and they were a fair price also. They were in the regular bolt section and not even in the little plastic boxes, so I got their bags and dumped a bunch of each size into some bags and headed to the register happy with the price for what I had. They are not as tall as the very old nuts, but they do look nice when installed.

Jim If you are working on an engine, usually what you want are high crown hex nuts and bolts. I think a sponsor has those. I ve had good luck stripping them off old scrap yard machines. You dont mention why you need them, so I wonder do you really need square nuts and bolt?

The square head maybe correct for some cart. Bolt grade would not be an issue there? Then sometimes cariadge(?sp) bolts are origional more appropriate a cart.

Depending on how they are made, usually longer bolts and be threaded down father with a die and the excess cut off, or just cut the excess. So a box might not be so bad, if you plan a collection around more of the same of what ever it is you are doing. You may pay a flat rate shipping and few boxes same as dozen pieces.

Thanks for info everyone, Jeff below are the sizes I'm looking for do you think Ace would have these?

John,

I only bought nuts and they were what you listed above.

But remember, Ace IS the place.........................sorry, couldn't stop myself.

Peter,
Please tells us which sponsor has high crown bolts.

Another thought, We make our own for what ever we need.

If you have a welder, a lathe, and round stock, and square stock, You can make them yourself. (nuts and bolts) Not that hard when you need a few of them.

Beats waiting for the UPS or going to the hardware store.

Besides, you can make them look just like you want.

Just a thought,

Jim I've purchased square head bolts from McMaster-Carr before to use on restoration projects. The nice thing is that you can order them unplated in most sizes. My only gripe is that the heads are embossed with the requisite traceability markings to identify the manufacturer. Nothing you can't face off quickly in a lathe though. Plus, that puts some tool marks on the face of the head to give it a more authentic look. Lowe's and most hardware stores have a selection of square nuts. Jim,

Fastenal supply told me they had a hundred dollar minimum order on their bolts and nuts. Mcmaster-Carr sell them by the bulk 25,50,100 box count. It can get pretty expensive when you need 5 or 6 different size bolts,nuts and lengths. I need square head bolts from time to time and I would rather purchase them then spend my time making them. I use the square head bolts and nuts on carts and also on a cement mixer that I'm curently restoring that originally had all square heads that were in real bad shape. I'm thinking I will have to break down and purchase them by the box.

I'll check out Hit & Miss...

Thank's

For screws going into wood there should always be a pre-drilled hole. Without a hole the difficulty installing a screw gets much worse, the holding power decreases and the danger of splitting the wood increases. A good rule of thumb is that the pre-drill should be slightly smaller than the root diameter of the thread. It is best if it is a little larger in very hard wood and a little smaller in soft wood. Some adjustment may be required depending on the particular conditions. Some common recommended sizes are listed below.

We have found there is no consistent meaning in the industry of what customers expect when they ask for certs. We are happy to provide whatever certifications are requested by the customer. Our normal “cert” is a statement for each shipment signed by an authorized company official that the parts meet their requirements. This is acceptable to most customers. If you require more specific information we can produce your required detailed documents, country of origin certifications, steel chemical certs and even mechanical testing reports from our lab.

We do import some nuts, washers, castings and a few specialty bolts. We typically only import when we do not have the capability to make the part and we can’t find a competitive source in the US. We import from a limited pool of vendors that we have established an ongoing relationship with and that have demonstrated the ability to produce parts to our standards. All imported parts are carefully inspected and fully tested in our Colorado plant and are required to live up to the same high standards as the fasteners we produce.

For more information, please visit Square Nut Supplier.

We forge raised head marking on to almost every fastener we make. Every part will have an LB which is our registered trademark to identify fasteners that we make. Beyond that, parts may have grade markings or may have the year or year and month the head was formed. Other identification can be added as needed. These marking help customers know what grade the fastener is and can help us determine when it was made for traceability.

Occasionally a fastener that we supply may break. Frequently the causes of failures are quite complicated and sometimes are never fully understood. Studies have show that at least 75% of the fasteners that fail in service do so as a result of application or (improper) installation issues. If you feel you have a defective fastener or group of fasteners, we will replace it. Whenever possible we would like the opportunity to investigate. There are a few things that would help us investigate a failure:

1. The broken part: The pieces of a broken fastener are instrumental in determining what went wrong. Feel free to contact us and we will pay for shipping for broken parts to use in an investigation. We prefer to see the part just as it was found. Do not clean it or fit the pieces back together again. Package it carefully to avoid damage to the fracture surfaces in shipping.

2. The lot number: Your PO number or any other information on when it was purchased. All of our packages are marked with a lot number. With that number we can easily obtain the history for those parts, including raw material identification, inspection records, and testing and heat treat records. If there is a date marked on the head that can also be very useful.

3. Any details on the circumstances of the failure: Things such as pictures, sketches or descriptions are also very useful. While failures and faulty fasteners are rare, we are here to help solve your problems, whatever the cause.
