The ifx_screw_data.cfg Configuration File
In the ifx_screw_data.cfg file located at <creo_loadpoint>\Common Files\ifx\configuration\, you can configure the values used in the Screw Fastener Definition dialog box. See the column headings and values of the ifx_screw_data.cfg file in the tables below. Each table describes a different section of the file. When editing this file, be sure to press TAB to separate values.
In the THREAD DATA section of the ifx_screw_data.cfg file, enter the thread values for the columns DG and P. If the values are not defined in the DAT file, they are taken from here. The default value for Metric is ISO THREAD DIN 13 and for UNC, Unified Coarse Thread Series. The values described in the table below are required for the 2D preview of the thread.

In the COUNTERBOREDIAMETER FOR SCREW’S section, enter the values for the counterbore diameters on the screw side. You can add your own columns. The values appear in the Side 1 – Counterbore lists in the Screw Fastener Definition dialog box. The default values are listed below:
• DIN 974-1:2008-02
◦ Diameter of counterbores - Manufacturing Dimensions
◦ Part 1: Hexagon socket head cap screws and screws with cheese head or pan head
• DIN 974-2
◦ Diameters of counterbores for hexagon bolts, screws and nuts; manufacturing dimensions
You can preselect the columns for the screws and the washers on the screw side. Write #CBSCR <COLUMN> to the DAT file.

In the ADDITIONAL COUNTERBOREDEPTH FOR SCREWS AND NUTS section, you can add value to your counterbore depth. If you select the Side 1 – Counterbore check box or the Side 2 – Counterbore check box, then the depth of the counterbore is calculated automatically, based on the height of the screw or nut head and the heights of the washers. Use ADD_DEPTH to add more depth so that the fastener is not flush mounted. COUNTERBOREDEPTH can be summarized in the equation below:
COUNTERBOREDEPTH = HEADHEIGHT + WASHERHEIGHTS + ADD_DEPTH

In the MIN and MAX (Screw-in depth for screws) section of the ifx_screw_data.cfg file, enter the minimum and maximum screw-in depth. In the Screw Fastener Definition dialog box, if you click 
Set length automatically or 
Permanently set length automatically, the application searches for a screw length within these limits.

To access these special values, you have to add the following line to ‘Section 1’ (Fastener Information) in your fastener data file (*.dat):
MUSCR 1587
or
MUSCR JND
If you do not enter a MUSCR value, then the default value is taken.
