Hole dimensions for plastic assemblies
Hole dimensions for aluminum and magnesium die casting
Hole dimensions for sheet metal assemblies
Recommended boss design and hole dimensions for different types of thermoplastics (PA, ABS, PPA+30GF...).
Select the units to calculate the dimensions of the hole. There is the option of mm and inches. These units are independent of the unit of measurement of the screw, i.e. you can select inches or a screw in metric size.
Choose the type of fastener for which you wish to calculate the hole dimensions. If you are in doubt about the type of product to use, please contact our application engineers.
Get the pilot hole sizes for APTITE 2000®, REMFORM®, FASTITE 2000® and STRUX SM™.
This calculation will depend on your design and the mechanical requirements of the assembly. If required, our technicians can help you to determine the optimum diameter for your application.
