Educational Website Covering F1554 Anchor Bolts.
F1554 Anchor Bolt MicrositeIn October of 2008, Portland Bolt created an educational website with the intent of providing technical information about ASTM F1554 anchor bolts to engineers, contractors, steel fabricators, OEMs and other construction-related companies. As this specification has now become widely used in the fastener industry, we felt the need to provide a comprehensive technical resource covering all aspects of this anchor bolt specification.

Over the past 3-1/2 years, F1554anchorbolts.com has become such an important resource that we have begun developing new microsites containing fastener-related technical information for several different industries and product lines. The content of each website is being developed by a different estimator here at Portland Bolt. We will feature a new microsite in our bimonthly newsletters beginning in May of 2012, when we introduce an educational website covering shear plate timber connectors. Shearplates.com will contain technical information related to shear plates, a special connector which is set in pre-cut daps in wood timbers and designed to spread the load, reducing the number of bolts required. Features will include photos and drawings of the connectors and cutters used to install them, a brief history related to the development of timber connectors, and a video demonstrating proper installation techniques.

FAQ – Bolt Length Tolerances

Q.  What are the tolerances for the length of a bolt?

A.  Length tolerances vary depending on the type and grade of bolt. 

Many smaller diameter bolts with short lengths have very precise length tolerances, while large anchor bolts manufactured to the F1554 specification have very generous length tolerances.  For example, a 3/8″ x 1″ hex cap screw will have a length tolerance of +/- three hundredths of an inch (+/- .03″), while an F1554 anchor bolt over 24″ long will have a length tolerance of plus or minus one full inch (+/- 1″). With such a disparity in bolt length tolerances existing in our industry, we have summarized this information in this bolt length tolerance FAQ.

Port of Brookings Harbor

Brookings, OregonportofbrookingsWhen the catastrophic tsunami hit Japan in March of 2011, the effects were felt as far way as Southern Oregon. The Port of Brookings Harbor sustained major damage, with the tsunami destroying 70% of the port’s commercial basin.

For the reconstruction of the port, Portland Bolt manufactured over 2,000 galvanized rods in various lengths, which were used to hold together the floating docks. We also provided several pallets of hex bolts, all thread rod, nuts, and washers.

Portland Bolt’s roll threading and in-house galvanizing capabilities help make us an extremely efficient and high-quality manufacturer for marine projects. See other projects.
