L-GoFix® A2 screws have been designed by Austrian timber engineers to achieve optimum timber performance and detailing. 

Patented L-GoFix® A2 screws are precision milled from hardened, A2 grade stainless steel. The sharp flanks of the screw thread allow the best possible anchoring without causing the timber to split and the precision milled splines on the shaft ensure that Scotlarch®, Thermopine®, SILA A/B®, Architect Select® Western Red Cedar and Accoya® do not require pre-drilling. We would, however, recommend pre-drilling hardwoods such as Garapa.

The small diameter of the flush-drilling 3-step head allows for clean, consistent detailing within your project. Tip: for optimum structural wood protection by way of enhanced ventilation, and in order to reduce the shearing pressure on screws (due to natural movement of the wood), we recommend the use of KompeFix®.

  • Stainless steel is the name given to a family of corrosion resistant (not corrosion proof) steels containing a minimum of 10.5% chromium. There are three main grades of stainless steel used for screws; 410, 304 (A2 grade) and 316 (A4 grade); each has different properties that make them ideal in the correct situation.
  • For use class 3.2 (i.e. facades subjected to frequent periods of wetting) grade 304 (A2) grade stainless steel screw is recommended. 410 grade can be used in areas subject to use class 3.1 (i.e. covered facades, infrequent wetting).
