The App is based on worldwide approach of guideline VDI 2230. Just select minimum of parameters and see the resulting tightening diagram as well as the force elongation diagram. As a small version of the huge software package Screw-Designer it follows the same input strategy: starting with default values and refining to the own application.
An elastic tightening specification is provided for your screw selection which san be modified. Corresponding safety-factors are provided for tightening and operating state.
With this convenient tool it is possible to make a fast pre-design of your fastening systems. For limitations see help section of Screw-Designer Basic. If you have to engineer a fastening system in detail, use Screw-Designer full version or contact us, because optimized fastening systems are getting more and more important and can save a lot of money.
New: Factor-approach to preload relaxation. It extents the traditional preload loss by seating. Resulting from this much more reliability is achieved, especially when using light materials and/or high preload level.
Units can be changed between metric and imperial, so a comparison of thread systems is easy.
Following thread profiles are covered:
M3 - M64 (coarse and fine), MJ, UNC, UNF, UNJF
Following materials for the screw can be selected:
Steel 4.8 - 16.8, Aluminum
Following materials for clamped part can be selected:
Steel, Aluminum, Cast Iron, Magnesium, Plastics
The start page provides alternating important tips for engineering design of screws.
