Template for Hexagon Head Screws

ISD_VORLAGE_SECHSKANTSCHRAUBE.IPT

For hexagon head screws the files

• ISD_VORLAGE_SECHSKANTSCHRAUBE.IPT and
• ISD_VORLAGE_SECHSKANTSCHRAUBE.KRA

are available.

Properties and Terminology

With regard to terminology, the following is assumed: Collar = Flange and Ejector = Dog point.

The following can be defined:

• Screws with and without collar
  controlled by the table columns C and DC
• Screws with and without dog-point
  controlled by the table columns DP and Z2
• Screws with and without shank
  controlled by table columns B, Z2 and LN

 

Due to the given category, it is not a thread-forming screw, i.e. in the Bolting function only threaded processing operations are offered as processing for the last part to be bolted.

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
C	Collar height	Value = 0 The screw is created without a collar Value > 0 The screw is created with a collar. The value must be > 0 exactly when DC > 0.
DC	Collar diameter	If = 0: Screw is created without collar Must be > 0 exactly when C is also > 0
DN	Nominal diameter	Must be > 0
P	Pitch of thread	Important for the bolted connection, e.g. to be able to assign suitable further fasteners (nuts). The table value must be equal to the actual thread pitch, which is generated in the template by a thread feature without considering the values for P in the screw table.
DP	Diameter of ejector	If = 0: Screw is created without dog point. Must be >0 exactly when Z2 > 0.
K	Head height	For screws with collar, the collar height is not part of the head height!
B	Thread length	For screws without dog point: If B = LN, the screw is created without shank (thread up to head); otherwise B < LN. For screw with dog point: If B + Z2 = LN, screw without shank is produced (thread up to head); otherwise B + Z2 < LN.
LN	Length	Length of the screw without head and collar, but possibly incl. dog point
SW	Width across flats
Z2	Length of ejector	If = 0: screw is created without dog point Must be > 0 exactly when DP is also > 0
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.

 

To be able to use an ISD template as a basis for your own standards tables. To do this, you must first create a copy of the template table. When you do this, a copy of the KRA file is also created automatically. You can then extend the copy of the table with additional data records. Or you can use the KRA file to define individual bolts and screws.

Bearbeiten des parametrischen 3D-Modells

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

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

• with and without collar,
• with and without dog point, and
• with and without shank

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.

 

A simple example:

We again take a look at the above example. The hexagon head screw in our copy My new table is not to have a DIN 13-16 thread, but a DIN 103 thread.

• Load the file MY_NEW_TABLE.KRA from the folder WERKSNORMEN (Factory standards).

• In the Feature log, double-click on the entry Thread DIN 13 M-6 and select the thread DIN 103 in the catalogue.

• Save the KRA file in the WERKSNORMEN folder (Factory standards).
