ISD_VORLAGE_LINSENKOPF-BOHRSCHRAUBE_INNENSECHSRUND.IPT
For hexalobular socket oval head drilling screws the files
- ISD_VORLAGE_LINSENKOPF-BOHRSCHRAUBE_INNENSECHSRUND.IPT and
- ISD_VORLAGE_LINSENKOPF-BOHRSCHRAUBE_INNENSECHSRUND.KRA
are available.
The table ISD_VORLAGE_LINSENKOPF-BOHRSCHRAUBE_INNENSECHSRUND.IPT
Properties and Terminology
- Screws can be created with and without a pre-mounted washer, controlled by the table columns D2 and S
- Screws with and without shank can be created, controlled by table column A
- Two different tip (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.

STATUS |
The status has an effect on the selection of standard parts in HiCAD. |

SIZE |

Thread x Length The value is used as a parameter for selection in HiCAD. |

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 |
|
| K | Head height | |
| RF | Oval head radius | |
| R | Radius | |
| 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 or the pre-mounted washer. |
| 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. |
| D2 | Outer washer diameter |
These values determine the shape of the pre-mounted washer. Either both values = 0 (no washer) or both values > 0 must be used. |
| S | Washer thickness | |
|
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. |
|
DS |
Drill point diameter |
|
|
LN |
Length |
This value determines the length of the screw without head, if necessary incl. pre-mounted washer. |

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 |
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. |

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 dependency INNENSECHSRUND 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.
The parametric 3-D model
The ISD template is based on a parameterised 3-D model named ISD_VORLAGE_LINSENKOPF-BOHRSCHRAUBE_INNENSECHSRUND.KRA.
This KRA file is parameterised in such a way that oval head drilling screws
- with and without pre-mounted washer,
-
with and without shank and
- with two 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.
