La serie S4 es una grapa de construcción para carpintería, cubiertas, fachadas, industria y embalaje.
Tiene la misma sección de alambre que la serie 155 y una corona más ancha, de 12,1 mm frente a 10,7 mm. La corona más ancha reparte el apoyo sobre una superficie mayor, algo importante en materiales blandos y tableros finos.
Evaluación Técnica Europea ETA-18/0879, emitida por el Deutsches Institut für Bautechnik de Berlín; sobre esa base se ha emitido la Declaración de prestaciones DoP 3/2019. La grapa se puede utilizar cuando el proyecto exige una capacidad portante declarada.
La serie se fabrica en varias versiones de alambre. La evaluación cubre dos: NKH, alambre galvanizado con un recubrimiento de zinc de al menos 12 µm, y A2, acero inoxidable AISI 304. Las demás versiones no están certificadas.
Las patas están recubiertas de adhesivo, que se funde por fricción durante el clavado y une la grapa a la madera.
Evaluada para las clases de servicio 1 y 2, en condiciones secas o temporalmente húmedas. Evaluación y declaración de prestaciones: /es/certificados/
