Over the years, we have sought to embrace the innovation and diversification that is made possible by constantly advancing technology. It is in that spirit that we were happy to partner with Lindapter, becoming one of Lindapter's full line distributors in the United States.
Among Lindapter’s most innovative and advanced products is the Hollo-Bolt, a bolt used to connect structural steel to hollow structural sections (HSS). Though not the only way to connect steel to HSS, the Hollo-Bolt is among the most reliable and simple to install.
Here are 7 things you should know about the Hollo-Bolt.
1) The Hollo-Bolt is a proprietary expansion bolt. When the nut of an expansion bolt is tightened, a wedge forces the wings of an expansion sleeve to expand, locking the bolt in place.
2) Though designed for use with HSS, Hollo-Bolts can be used with any virtually any structural element that reduces or prevents access to the back of that element.
3) In accordance with AC437, Hollo-Bolt fasteners are incredibly strong. When used in load-bearing connections, they have been shown to resist shear and tensile forces of up to 11,490 and 12,410 pounds, respectively.
4) Installation of the Hollo-Bolt is simple, requiring only basic tools. After bolt holes are drilled, which can be performed in the fabrication shop, Hollo-Bolt installation requires only a hex wrench to hold the bolt steady and a torque wrench to tighten it. The Hollo-Bolt’s easy installation will help keep work time and cost low.
5) With 6 different models (includes Type LB2 - Lindibolt™ 2), including 6 patented High Clamping Force (HCF) sizes, there is a Hollo-Bolt for every job. They range in material clamping width from 1/8” to 3 5/8”, in bolt length from 2” to 6 3/16”, in tension resistance from 2,340 to 12,410 pounds, and in shear resistance from 2,000 to 11,490 pounds.
6) Often used in outdoor applications, Hollo-Bolts are available in Bright Zinc Plated, Hot Dip Galvanized, Stainless Steel (Type 316) and Sheraplex for added corrosion protection in a variety of environmental conditions.
7) The Hollo-Bolt has undergone a range of testing and certification. All Hollo-Bolt fasteners have been tested by ICC-ES, a third party ISO 17025 test facility. They are approved for use in Seismic Design Categories (SDC) A, B, and C, with approval for additional D, E, and F categories currently under review. They are in compliance with IBC 2009. Hollo-Bolts are also approved for the CE marking, by DIBt, and by TUV.
