Screw vs StressTable2023

The most easiest mobile calculation of tightening and loading of screw joints for reliable engineering of screw joints. 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.

Background ASME Sec II-D give the material stress, physical and mechanical properties table. There are some tools available for Table 1-A stress values determination at given temperature but no tool available for other tables for quick determination of properties at given temperature. Applicable Code / Edition & Standards This app is based on ASME Section II-D 2023 Edition for metric and US customary unit. Utility This app gives material properties at given temperature for different Code section, also help user to do the hand calculation using the values where no commercial design software is available in the market. Competitive Edge There is no app available in the market to cover most of the tables available in ASME II-D for material properties. This app fills that gap and facilitate user to use these values in hand calculation where no commercial software is available for particular Code section. Target Audience This app targets inspection agencies, pressure items manufacturing organizations, quality control personnel, Engineers and designers who are involved in pressure items design calculations. Non Consumable Subscription: You can download the app from App Store for free, however One time Non-Consumable subscription in-app-purchase is required before you can use any of the Tables of this app. Purchase can be made by going to the menu of the application. Terms and condition are also provided there.
