Nails & brads

Frequently asked questions — Nails & brads

• How do I choose between smooth, ringed or twisted nails?

  The choice of type depends on the holding requirement specific to your application. Smooth nails are commonly used for standard assemblies, while ringed or twisted versions offer superior pull-out resistance. It is essential to assess the mechanical characteristics of the product in relation to the applied load and the nature of the substrate, whether softwood or hardwood, to ensure the long-term durability of your industrial assembly.
• When should nails and brads be preferred over metric-thread screws?

  Nails and brads at MecaIndus represent a fastening solution that complements nuts and bolts or metric-thread screws. They are essential for rapid assembly operations and the fixing of lightweight structures. If your assembly requires very high mechanical performance, threaded fasteners should be considered. For the latter, standards such as ISO 898 may govern strength classes, unlike nails.
• Which environmental criteria should be taken into account when selecting fasteners?

  The selection must take into account the environmental conditions of the hardware's application. Exposure to the elements can influence the long-term hold of the assembly. These factors must be cross-referenced with the nature of the substrate, whether composed of wood or composite materials, in order to choose the most suitable reference from the RAPID, ARCELOR, SENCO, SIMPSON and RAWL brands available in our range.
• Does the ISO 898 standard apply to my nails and brads?

  It is important to note that the ISO 898 standard, which governs strength classes, mainly concerns threaded fasteners such as bolts or metric-thread screws. If you are looking for fasteners that meet strict normative requirements for complex structural assemblies, nails and brads do not follow this reference. However, dimensional and technical conformity remains a priority criterion for all your industrial assemblies, respecting the specifications of each type of nail.
