How is a Square Machine Bolt Made?
Square machine bolts, also referred to as crossarm bolts, square head machine bolts, or simply machine bolts, are the most commonly used bolts in wood pole overhead line construction. These bolts typically fasten wooden crossarms to utility poles.
There are dozens of products in the pole line industry, such as insulators, grounding products, and deadline hardware., which Portland Bolt does not provide. Instead, we choose to focus on the specialized bolts and fasteners involved in the pole line industry.
There is pole line-specific technical information to be found on our specialty website www.polelinefasteners.com. Want to see how a square machine bolt is manufactured and galvanized? Let our resident pole line fastener expert, Anthony Porreco, walk you through a step by step video of how we do it!

Anchor Bolt Fixes
Common anchor bolt problems often faced by contractors in the field include anchor bolts that are installed either too high or too low or anchor bolts that are damaged once they have been poured into a foundation. AISC Design Guide 1 addresses both issues, which our technical expert, Dane McKinnon has summarized in the FAQ area of our website. In our July 2013 Newsletter, we will address misaligned anchor bolts. For answers to these and other common fastener-related questions, visit our FAQ section frequently or subscribe to our RSS feed, as we are constantly adding to the current database of over 130 entries.
Portland Bolt brand shear plates, split rings, and installation tools have arrived!
Two integral components of the Bishop Road Bridge project highlighted above were shear plates and split rings (pictured above). Collectively referred to as “timber connectors,” these products help to reinforce wood structures. Talk to John Wunderlich, who maintains our specialty website, www.shearplates.com, for more information about various timber connectors used in wood construction, or visit the Timber Construction and Glulam page of the Industries Served section of our website for more information about timber connectors and other fasteners used in timber construction.
