Wall Plugs

Frequently asked questions — Wall Plugs

• How do I choose the wall plug suited to my substrate?

  The choice of a wall plug is determined principally according to the nature of the substrate material and the mechanical stresses applied to the assembly. It is essential to assess the load that the fastening will have to support in order to guarantee its durability over time. This selection forms an integral part of MecaIndus's fastening and screw range, which also includes threaded rods, metric thread screws and rivets, in order to meet the requirements of your working environment precisely.
• Should I use a wall plug or another fastening system?

  The use of wall plugs is recommended when the substrate configuration requires specific anchoring to ensure the durability of the assembly. If your project involves more complex assemblies, MecaIndus's range offers complementary alternatives such as threaded rods and bolts, rivets and inserts, or metric thread screws. The decision depends on the dimensions required and the type of mechanical loading, the wall plug being dedicated to fastening within the substrate material.
• Which standards must the fasteners used with my wall plugs comply with?

  In assembly projects using threaded components, it is essential to refer to the standards in force to ensure technical compliance. Fully threaded hexagon head screws must conform to ISO 4017 or DIN 933, whilst partially threaded ones follow ISO 4014. For type 1 hexagon nuts, compliance with ISO 4032 or DIN 934 is required, and plain washers are governed by ISO 7089.
• Which property class should I choose for my steel fasteners?

  The mechanical properties of steel fasteners, in particular property classes 8.8, 10.9 and 12.9, are strictly defined by the ISO 898 standard. The choice of class depends on the mechanical stresses specific to your application in order to ensure the safety and longevity of the assembly. This classification allows you to select the strength suited to the loads that the fasteners, used in conjunction with or in support of your wall plugs, will have to bear in your working environment.
