Definitions

  • the present disclosure generally relates to fasteners. More specifically, the present disclosure relates to a fastening system having a fastener or pin configured for fastening structural support framing and/or support members to each other.
  • Fastening systems including pin fastening technology have been common in the construction industry for many years and include a pin that can fasten a material to steel as securely as a common conventional screw fastener.
  • Pins are made of special grades of steel that are hardened making them ductile and extremely strong. When driven into steel with the proper power driven tool, the ballistic-shaped point of the pin uniformly pierces the steel instead of drilling it out or tearing like a common nail. The displaced steel rebounds around the pin to create a strong compressive force on the shank of the fastener. This force, working in conjunction with a pin knurling pattern, creates a high friction force that prohibits withdrawal of the fastener from the steel.
  • LGS Light Gauge Steel structural framing
  • LGS framing has the benefits of versatility and strength with a high strength-to-weight ratio to provide enhanced design possibilities for architects.
  • LGS framing is also lightweight, straight and true, making it easy to handle and install, thus providing many benefits for builders.
