EJOT gets FM Approval for single-ply flat roofing fasteners

  • 17 Jun 2022

Construction and industrial fastening systems manufacturer EJOT has added another significant quality standard to many of its flat roofing fastener and washer combinations by gaining approval from American testing institute, FM Global.

The internationally-recognised FM Approval on a significant number of EJOT single ply flat roofing products corresponds with, and complements, the company’s existing European Technical Approval (ETA), confirming the safety, reliability, and durability of the flat roofing product combinations. 

Importantly, unlike the European assessments that focus on the individual product’s performance capabilities, the FM Approval process looks at the complete assembly by testing an entire roofing system – the fastener, substructure, insulation material and roof sheet. 

The EJOT fastener and washer combinations tested include the EcoTek tube-washer with FBS-R fastener, which is a popular choice for attaching membrane and insulation to concrete, as well as TKR/TKE fasteners with the HTK 2G 50 tube-washer. This is typically used when attaching insulation and a single layer waterproof membrane to a steel or plywood deck. 


Successfully passing the rigorous testing process in various roofing membrane combinations gives these fastener/washer combinations FM Approvals Standard 4470. This provides additional certification to support the products and maintain their worldwide use in the flat roofing market.

As a result, EJOT can present greater flexibility and security for OEMs globally, with design data being available not just within the ETA but from the FM Roofnav design database.

‘Another quality dimension’

Kevin Rackley, Product Manager for membrane system fasteners at EJOT UK, comments: “FM Approval adds another quality dimension to our most widely used single ply flat roofing fastener/washer combinations, confirming the standards we have already demonstrated in Europe and giving specifiers and OEMs across the globe a recognised seal of approval. 

“FM Approval has become an increasingly important factor for investors and building owners throughout Europe who are demanding the American quality certificate, so it was only right that we as a responsible OEM that we responded to the market needs by gaining approval. 

“It will also support the use of our products in international construction projects where FM Approval can be a major factor, particularly where there is a requirement in the tendering process in order to comply with FM Global’s insurance standards.”

As one of the leading manufacturers of fasteners for the construction sector, EJOT UK is ideally placed to advise on the correct fastening solution for any roofing and cladding project.

Its range of fastener and washer combinations for single-ply flat roofing is one part of an extensive portfolio of solutions for the building envelope, which also includes high performance fastening systems for rainscreen, profiled sheets, sandwich panels and external wall insulation, as well as concrete anchors.
