Blind Bolts for Structural Steel: A Buyer’s Guide
Quick Answer: Blind bolts are structural fasteners that install entirely from one side of a connection. They are the standard method for bolting to Hollow Structural Sections (HSS), where the inside of the tube cannot be reached. Blind bolts install with basic hand tools, require no welding or on-site drilling of the supported structure, and…
BoxBolt vs. Hollo-Bolt : Which Blind Bolt Is Right for Your HSS Connection?
When engineers need to make a blind connection into hollow structural steel, two products come up consistently in specifications: BoxBolt by LNA Solutions and Hollo-Bolt by Lindapter. Both are well-engineered, ICC-approved solutions for HSS connections. Both eliminate the need for through-bolting or welding. Both are trusted on major projects. So how do you choose between…

How to Connect Hollow Structural Sections from One Side
Quick Answer To connect Hollow Structural Sections (HSS) from one side, use a blind bolting system such as BoxBolt®. Its expanding sleeve grips the interior wall of the steel section, forming a secure, load-rated, and code-compliant connection without welding or backside access. The HSS Connection Challenge Hollow structural sections offer excellent strength-to-weight ratios, but their…
