ANN ARBOR, Mich. – LNA Solutions, Inc. announced that its BoxBolt is the first blind fastener to receive an International Code Council (ICC) Evaluation Service Report for use as ICC-ES ESR-3217. ICC is an accrediting association dedicated to developing model codes and standards used in the design, build and compliance process to construct safe, sustainable, affordable and resilient structures.
BoxBolt provides a safe, secure means of connecting rectangular, circular, or square hollow tube steel for cladding, curtain walls, blast walls, cell tower, reinforcement, and in other applications where access to the tube is limited to the opposite side of the connection, according to LNA Solutions. No on-site drilling or welding is required, and installation is fast and easy using basic hand tools. BoxBolt connections offer a guaranteed safe load and provide aesthetic detail plus a corrosion-resistant finish. It is available in diameters of 1/2-inch, 5/8-inch, and 3/4-inch, each with three different lengths.
The method of using “blind-bolt type” fasteners has been recognized since 1996 in the AISC Steel Construction Manual (Section 7-13) as an alternative to welding; however, it was not a certified solution by an accrediting agency.
“Our customers have been asking for us to acquire such approval, with the need to have an ICC Evaluation Report being the most common request,” according to Terry Doran, Vice President of LNA Solutions.
“Since no other blind fastener had ever undergone the evaluation process, ICC required that we develop an Acceptance Criteria (AC) for BoxBolt,” Doran said. “We then began working with Ronald Hamburger, Senior Principal at Simpson, Gumpertz & Heger to develop what is now known as AC437. This was approved by ICC-ES for testing.”
BoxBolt is the only blind fastener that has an ESR from the ICC-ES.
