    Many years ago, I serviced the forklifts for Portland Bolt. At the time, they stood out to me as a top quality organization. Glad to see that they are still making a quality product in the time honored American tradition.

    I met some of your competition: a farmer up Highway 8, north of Hamilton, Ontario, has a $500,000 four-axis machine out in the barn, spends a few hours a day carving bolts out of raw stock, custom-made for customers like Hydro-Quebec.

      Hey Ken!
      We do not make fasteners that small. We cut threads on all the lag screws we make from 1/2" diameter and larger.
      On a lag screw that small in diameter, the threads are likely rolled.

    Wouldn't the bolts have a greater tensile strength is the threads were rolled and not cut?

    • @pdxbolt
      @pdxbolt  8 років тому +9

      You are correct; rolled threads will likely produce stronger threads due to the work-hardening from roll threading and the fact that cut threading interrupts the natural grain structure of the steel. However, cut threading still produces a product that will meet the dimensional and minimum mechanical requirements of the F1554 specification. You can see more about the differences between rolled and cut threads in our videos: ua-cam.com/video/MvWmH3Dr52o/v-deo.html and ua-cam.com/video/4itib5n9AxY/v-deo.html

    • @Dr_Xyzt
      @Dr_Xyzt 7 років тому

      That's true, but the very fact that the diameter reduces from the shank aggravates the problem more than anything else. Back in college, we designed portal axles for our mini baja sae car. We didn't conventionally design the bolted joints. Instead, the bolt hole went 2.5 shank diameters into the anchoring flange before the threads even started. So not only did we have a good slip critical fit, but even if the bolts backed out, they were designed to function as pins anyway while the shank even behaved as a locating dowel. Saving weight on a handful of bolts is nothing compared to what you get from directly reducing design complexity.

    • @CoolKoon

    Are they heat treated? I would think the head forging would soften the metal.

    • @pdxbolt
      @pdxbolt  7 років тому

      +George Applegate - The F1554 Grade 36 anchor bolts manufactured in this video do not require heat-treatment. However, many grades of anchor bolts do, including F1554 Grade 105. F1554 Grade 36 anchor bolts are made from A36 steel and shipped in an "as-forged" condition. The heat from the forging process has little to no effect on the strength and performance of the product.

  • @junkdeal
    @junkdeal 6 років тому

    Before the invention of the wire nail machine, they used to shear wedge-shaped blanks out of iron plate, and a heading technique put the rose-head on a lot like the hex machine here. A type of upset-forging. Some thread technique on heavy bolts involves starting with a rod of a diameter between the root diameter and the external outermost thread diameter of what would be the finished product. The threads are hot-rolled (I think) onto the rod. There is no metal removed, and the strength of the actual diameter of the unfinished rod is not compromised by metal reduction. The threads do stand taller than the diameter of the rod though, due to the flowing upward of the displaced metal to the finished diameter of the outer edge of the thread.

    Thank you for posting this great video and showing us how you mfr bolts! I hope in the years since posting, that you have somewhat updated your processes to make them more efficient. I hate to be the one to say it, but the labor involved seems in excess of what could be used. There's a lot of hand-handling that could be streamlined. I'm not even saying to use robots, but just by redesigning your jigs, introducing new jigs and other devices, you could make your labor more efficient. I'm not sure what your economic challenges are; whether you are protected somewhat through domestic procurement requirements, but you could protect yourself with greater efficiency. I'm not intending to just be critical, but to encourage actions that will keep more jobs here in the country. Thank you!

      CuriousEarthMan - Thank you for your comments. We always welcome suggestions that will help us improve. Many construction fasteners are mass-produced using automated bolt-making equipment. These mass-produced bolts are relatively small in diameter, relatively short in length, and used in large numbers. Thousands of bolts in the same size and grade are manufactured in a single run.
      We are not a mass-producer. At Portland Bolt, we manufacture larger, nonstandard bolts in relatively small quantity runs. We are essentially a job shop. We make anywhere from a single bolt to runs of a few thousand. Due to the small quantities and larger sizes, automation is a challenge. Therefore, most of the companies like our in this little niche market of making large, nonstandard bolts make them one at a time by hand. There is a certain degree of craftsmanship that takes machine operators years to perfect.
      We would welcome specific examples of streamlining our processes. However, the bolts we make now have been made this way with little change since the inception of our company in 1912.

      @@pdxbolt Thank you for responding! I would like to humbly submit a few detailed suggestions based on your response and your video. May I do that through email? To whom shall I address those suggestions, and to which email address? I am inspired by your long tradition of successful manufacturing, and perhaps there might be an item or two that helps you, not to correct you, but to serve your benefit in some way. Please let me know. Thank you!

    I used to make bolts for Bethlehem Steel I made cold formed bolts from 1/4 inch in dia. To 1-1/4 in dia any length ordered --And had to run two machines at one time ---usually a 1/4 inch mach. and a 5/8th mach.. I also ran at the time the largest cold forming bolt machine in the USA. Our machines cut the wire --formed the upset--formed the head and trimmed the upset to a hex then pushed the blank bolt up a hollow tub to a pointer then up a track to the roller dies, all in one stroke once all the stations were full.

    As a racer seeing cut threads scares me. Every bolt on a race car as well as aircraft have (or should have) rolled threads. Do you do any kind of stress testing or are the bolts designed to be so over-sized it doesn't matter?

    • @pdxbolt
      @pdxbolt  4 роки тому +2

      Lawrence Hayes - Fortunately, we do not make automotive, aerospace, or other critical fasteners that require a high degree of precision. We manufacture large construction fasteners that, by nature, have very generous tolerances. Construction fasteners can have rolled or cut threads. We roll threads through 1" diameter. You are correct that roll threading will typically produce a stronger thread. However, cut threading is a common practice in the construction fastener industry and all bolts are tested to ensure they are strong enough to meet the minimum requirement of the various ASTM specifications used for construction applications.

    Hi, when cutting the tread how much do you allow for the thickness of the galvanising please.?

    • @pdxbolt
      @pdxbolt  4 роки тому

      John Cone - Threads of a construction fastener are cut (or rolled) with the same dimensions and tolerance regardless of whether the finished fastener will remain in a bare-metal state or be hot-dip galvanized. Since galvanizing adds between 2 - 6 mils of zinc thickness to the bolt, it is the nut that is tapped oversize to accommodate the thickness of the zinc on the external threads of the fastener. This FAQ addresses the issue in detail: www.portlandbolt.com/technical/faqs/galvanized-nuts-tapped-oversize/.

      For many grades of fastener, heat treatment is required after the heading process. For some low carbon grades however, heat treatment is not required.
