Beam Clamps for Rigging and Lifting: Choosing an Anchor Point
Quick answer: A rigging clamp creates a certified anchor point on existing structural steel without drilling or welding it. LNA offers two, and the choice is decided by the steel, not the load. For an open flange, the BeamClamp Adjustable Rigging Clamp self-adjusts across flange widths from 4 to 24 inches and flange thicknesses from…
Wedge Lock Washers vs Nylon Insert Nuts, Split Washers and Jam Nuts
Quick answer: Nylon insert nuts, split washers, jam nuts and prevailing torque nuts all rely on friction to resist loosening. Friction varies from joint to joint and drops away under vibration and dynamic loading. A wedge lock washer works differently. It uses a pair of interlocking cam faces with an angle steeper than the thread…

C Style Beam Clamps: Hanger Clamps vs. Structural Clamps
Quick Answer: Two very different products share the name “C style beam clamp.” The first is a small set-screw hanger clamp used to hang threaded rod for pipe, conduit, and HVAC supports. The second is a structural C clamp, like the BeamClamp® Type BL from LNA Solutions, used to clamp steel sections directly together with…
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…
Heavy Duty Beam Clamps: Load Ratings, Types & When You Need Them
Quick Answer Heavy duty beam clamps are engineered mechanical clamps that grip structural steel flanges to carry high tensile, frictional, or suspension loads without welding or drilling. For BeamClamp® applications requiring the highest load ratings, the Type BY and BYP (high friction) models reach up to 7,524 lbs tensile per bolt and 7,733 lbs frictional…
What Is a Wedge Washer? How Wedge Lock Washers Work
Quick Answer A wedge washer is a mechanical bolt locking device that uses two hardened washers with interlocking cam faces to prevent bolt loosening under vibration and dynamic loads. Supplied as a pre-glued pair, wedge washers install like a standard washer but lock the joint physically rather than by friction. The cam angle is steeper…
BeamClamp® Load Capacity Guide: Safe WOrking Loads by Model and Bolt Size
Quick Answer BeamClamp® safe working loads range from 281 lbs (Type BA/BB, 5/16″ bolt) up to 7,524 lbs tensile per bolt (Type BY, 3/4″ bolt, medium friction). All loads are derived from physical testing, carry a 5-to-1 factor of safety, and are Lloyd’s Register Type Approved. The right load capacity depends on the clamp model,…
Steel Grating Fasteners: G-Clips, GrateFix™ & FloorFix™ Guide | LNA Solutions
Quick Answer Steel grating fasteners are mechanical clips that secure open bar grating panels to structural steel supports without welding or drilling. The three main types used in North American industrial construction are the Grating Clip, GrateFix™, and FloorFix™. Each is designed for a specific grating type, load condition, and environment. Choosing the right fastener…
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…
