Screws produced in Germany
SWG Schraubenwerk Gaisbach GmbH (SWG), based in Waldenburg, Germany, is a developer and manufacturer of a very wide variety of products for furniture construction, wood structures and especially for timber engineering.
cooperation between the company’s own development department and customers helps create products to meet the highest demands with great benefits for the customers – regardless of where they are in the world. SWG states that its extremely high level of quality, combined with

the sustainable and careful handling of the resources available, are ensured by its quality and energy management systems, complying with, and certified according to, DIN EN ISO 9001:2008 and DIN EN ISO 50001:2011. In addition, thanks to its modular technology building block
system, which allows the combination of various head, thread and point geometries, SWG can cover a broad and comprehensive CE product range with its own ETA. This applies from the smallest chipboard screws with a 3mm diameter to screws for timber engineering with a diameter of 14mm and a length of up to 1,500mm. High-quality and performance of the screws are ensured by SWG’s continuous surveillance and that of external bodies according to System 2+ (product certification). Such approvals are of great importance, not only in Europe but
also for the North American market. The granting of the approvals for screws manufactured by SWG production has already been obtained for Canada from the Canadian Construction Materials Centre (CCMC). For the US, SWG is currently in the process of obtaining approval from ICC-ES and expects to receive it shortly. This further underlines how SWG’s production can meet the high market and approval requirements in order to support the client

ue to decades of experience and cooperation with clients worldwide, SWG specialises in the development and production of top quality wood construction screws for a multitude of differing applications. The intensive
in the field of high performance timber engineering. However, not all screws are alike, with the performance of a
screw not necessarily being visible at first glance. An explanation is often required in order to grasp the actual performance potential of the screw in wood construction. SWG realised this and since January 2014 a five man SWG engineering team has been supporting the company and its clients in the planning and implementation of client construction projects. The in-house development of its own calculation software
for the sizing of screws rounds off the provisions of SWG Schraubenwerk Gaisbach GmbH production. “At SWG we provide competent, expert support in the planning and use of custom-made screws for wood constructions of all types, be it a sports hall, block house or sophisticated timber wood construction. This makes us a reliable partner in the field of timber engineering.”
