The table ISD_VORLAGE_ZYLINDER_SCHNEIDSCHRAUBE_INNENSECHSRUND.IPT

Properties and Terminology

Screws with and without shank can be created, controlled by table column A.
Two different drill point shapes can be created, controlled by the table column Y.

Due to the predefined category, the screw is a thread-forming screw, i.e. in the Bolting function only processings without thread are offered as processings for the last part to be screwed, and in the bore settings for the last part to be screwed, the blind hole setting and the specification of the minimum screw-in depth are offered.

The table template consists of the following columns, whereby the columns highlighted in bold are particularly important for customising the template. All specified values must be >= 0.

The table columns and their meaning
ID	Data record ID	Automatically assigned
MOD	Modification indicator	Automatically assigned
STATUS	Availability	The status has an effect on the selection of standard parts in HiCAD.
BZ	Description for selection when inserting in HiCAD	Article number attribute $BB
SIZE	Size of screw	Thread x Length The value is used as a parameter for selection in HiCAD.
MATERIAL	Execution class/Substance/Strength class
OBERFL	Surface type
TYPE	Sorting size	It is generally not recommended to change the sorting criteria given by the system.
TYP	Type of part	0 = fixed part, 1 = variant Here: 1
GEW	Thread designation
DN	Nominal diameter	Must be > 0
DK	Head diameter	These values determine the head shape. All values must be > 0.
K	Head height
M	Hexalobular socket No.	These values determine the geometry of the hexalobular socket drive and refer to the hexalobular socket table (table dependency to DIN EN ISO 10664 at Fasteners > General geometry).
MA	Hexalobular socket auxiliary dimension
A	Shank length	If A > 0, then the value determines the length of the shank. If A = 0, then the screw is created without a shank, i.e. the thread extends directly under the head.
P	Pitch of thread	This value is important for boltings, e.g. to be able to assign suitable further fasteners (nuts). The table value must match the actual thread pitch, which is generated in the template by a thread feature without considering the values for P in the screw table.
DS	Drill point diameter
Y	Drill point length	If Y > 0, then a drill point with the length Y and the diameter DS is generated. If Y = 0, then a point shape C is generated. DS is ignored in this case.
LN	Length	This value determines the length of the screw incl. head
KILO	Weight
CUSTOM1 - CUSTOM9	User-defined text	Customer-specific information
LKMAX	Maximum grip length	This column is not included in the delivered table. The column can be added manually and will then have the same effect in the bolted connection, as in all other bolts with this column. If the column is present, all values must be > 0
SET	BOM-relevance of sets	This column is not contained in the delivered table. The column (data type TEXT) can be added manually to set the BOM-relevance of the fasteners in a bolting with the screw.

Dependency	Table
INNENSECHSRUND	Fasteners > General geometry > DIN EN ISO 10664
SENK	Factory standards > User-defined processings > Templates > User-defined countersinks > Conical countersink with lowering

Please note:

In order to be able to use the ISD template as a basis for your own standard part tables, you must first create a copy of the template table. Please note that the dependencies INNENSECHSRUND and SENK must also be assigned to the copy. Otherwise, problems may occur when inserting boltings.

When copying the table, a copy of the KRA file is automatically created. You can then extend the copy of the table with further data records. Or you can use the KRA file to define individual bolts and screws.

Associated countersink table

The template table ISD_VORLAGE_SENKKOPF-BOHRSCHRAUBE_INNENSECHSRUND.IPT has a dependency (SENK) on the table Conical countersink with lowering. This table describes the shape of the countersink and is located in the catalogue at Factory standards > User-defined processings > User-defined countersinks > Templates.

The values in this table are particularly important for the placement of the screw in a bolting set. Therefore, you must make sure that the values in the countersink table and the screw table match. If necessary, the countersink table must also be copied and adjusted accordingly. The dependency of the copy of the screw template must then be set to the copy of the countersink table.

Please note:
Copying the countersink table cannot be done with the Copy table function as when copying the screw templates, but in this case you must use the New table with template function!

Example:

Let's assume that you want to use the template ISD_VORLAGE_SENKKOPF-BOHRSCHRAUBE_INNENSECHSRUND.IPT as a basis for your own screws and adapt the countersink table. This is how you proceed:

Create a copy of the countersink table. To do this, right-click on the table name and select the function New table with template. In the dialogue window, enter the desired table name, e.g. MY_COUNTERSINKS. This copy is created in the same folder as the countersink table.
Copy the ISD template of the countersunk head screw with the Copy table function. In the following dialogue window, enter the new table name - e.g. MY_NEW_TABLE - and, after clicking on the catalogue, select the catalogue in which the copy is to be storedl.
Under Dependency, select SENK and then your copy of the countersink table, e.g. MY_COUNTERSINKS.

Then close the dialogue window with OK.
You can then modify the copy of the screw templates (see Templates for Fasteners).

The parametric 3-D model

The ISD template is based on a parameterised 3-D model named ISD_VORLAGE_SENKKOPF-BOHRSCHRAUBE_INNENSECHSRUND.KRA.

This KRA file is parameterised in such a way that countersunk head drilling screws

with and without shank and
with different drill point shapes

can be generated.

For this purpose, the feature model of the file contains corresponding constraints and part variables. It is also ensured that all four sub-types of the screw are available, i.e..

exact representation with and without thread
simplified representation with and without thread

If you have created a copy of the table, a copy of the corresponding KRA file is also created under the KRA name specified when copying the table.

This .KRA file can be individually adapted - assuming appropriate knowledge of features and parametrics. However, it is important that the rules specified in the Properties and Terminology paragraph for the respective template are adhered to.

Please also observe the notes on the geometric properties.
