In the late 1940’s Lindapter revolutionised the concept of ‘blind’ fixing with the development of the Lindibolt. Following the introduction and wide acceptance of hollow section steelwork, the range was expanded to include the Hollo-Bolt. Continued development and expansion of SHS means a wide variety is available today - square, rectangular, circular and oval; options for diameters, lengths, finishes, and head types have also expanded. The Hollo-Bolt was awarded the Design Councils Millennium Products Award for Innovation in 2000 and is now included in the BCSA/SCI publication ‘Joints in Steel Construction’ – Simple Connections’, as well as being approved by the Deutsches Institut für Bautechnik. Lindapter cavity fixings give a simple, cost-effective solution when fixing to hollow section steel, or to steelwork where access is available from one side only. Eliminates the requirement for unsightly welding or strapping e.g. installing the Hollo-Bolt only requires two wrenches.
