System component Bolts in a part (1006) can be used to position a bolt pattern in a profile. Instead of bolts also studs or profiles can be positioned. Using bolts also user-defined attributes (UDAs) can be defined.

Objects created

Bolts, studs or profiles

Use for

Situation	Description
Image	Divide bolts along the length of a profile.
Image	Divide studs along the length of a profile.
Image	Divide profiles along the length of a profile.

Before you start

Model a profile or a plate.

Selection order

Activate the component.
Select a profile.
Select a point.
The bolts/studs/profiles will be created according to the component settings.

Picture tab

Tab Picture can be used to position objects (bolts/studs/profiles), the number of those objects and the way to divide the objects along the main part.

Option	Description
1	In Type choose the type of object you want to create. The options are: Default (same as option Bolts) Bolts Studs Profile 1. Bolt 2. Stud 3. Profile Image
2	This option can be used to define a distance between the selected point and the position where a fitting should be placed by the component. The options are: The default option. Image Profile remains the same. Image Define the distance for the line cut related to the system point of the component by using option 3. Image Define the distance for the fitting related to the system point of the component by using option 3. Image
3	Define the distance for positioning a line cut or a fit line related to the system point of the component.
4	Number of bolts/studs, distances between the objects and edge distances. The drop-down list below contains positioning options. The options are: Default (equal to option Not Exact)
	Not exact Image Image
	Exact to start of profile Image Image
	Exact to end of profile Image Image
	Exact to middle of profile Image Image
	Look at length of profile Image Image
5	Define the position of the pattern of the bolts/studs/profiles related to the defined position when placing the component. The options are: Image Example: Image Image Image Image
6	Define the shape of the bolt pattern. The options are: Image

Bolts tab

Use the Bolts tab to control the bolt properties.

Option	Description
Bolt size	Bolt diameter. The default value is `16` mm.
Standard	Bolt assembly standard/grade. The default value is `4014-8.8`.
Tolerance	Tolerance = Hole diameter - Bolt diameter. The default value is `4` mm.
Thread in material	Indicate if the thread of the bolt can be inside the bolted parts. Tekla Structures does not use this value when calculating the length of full-threaded bolts.
Bolt type	Define whether the bolts are assembled on-site or in the shop. The default value is `On-site`.
Rotate 90°	Option to rotate bolts/studs/profiles according to the main part in order to place the objects on top of the flange or to the web. Example: Image
Cut length	Indicate which parts the bolt connects. The value defines the area Tekla Structures should search for parts that belong to the bolt group. Using cut length, you can determine whether the bolt will go through one flange or two.
Bolt Comment	Bolt comment.
Slotted hole X and Y	Slotted hole dimensions can be set in x- and y-direction. These fields can also be used to set the tolerance of oversized and tapped holes. Image 1 = Vertical dimension of the slotted hole. 2 = Horizontal dimension of the slotted hole.
Offset	Option for defining an offset.
Bolt comment 2	Bolt comment 2.
Assembly	Select whether to create washers and nuts with the bolt. If you want to create only holes without any bolts, clear all the check boxes. Image The option Effect in modify enables the bolt assembly to be modified in existing components when the existing component is modified.
Extra length	Additional bolt length. Increases the material thickness that Tekla Structures uses when calculating bolt length. For example, you might need extra bolt length to allow for painting. Image You can also build additional lengths into bolt assemblies.

Studs tab

Tab Studs can be used to define the diameter and length of the studs.

A stud is a special kind of bolt and will be welded to the profile/plate. The studs in this tab are objects of type "bolt" using the standard "STUD".

Option	Description
1	Options to use regarding studs: ● Default ● 10 ● 12 ● 16 ● 20
2	Available stud standard: ● Default ● STUD
3	Options for stud lengths: ● Default ● 50 ● 60 ● 70 ● 80 ● 90 ● 100 ● 110 ● 120 ● 130 ● 140 ● 150

Profile tab

Tab Profile can be used to define the dimensions of the profiles.

In case in tab Picture the drop-down list Type is set to Profile, this tab can be used to set the properties of the profiles.

In case no profile will be defined, the profiles will have next properties:

Profile = D30.

Length = 50 mm.

Options	Description	Standard
Profile	The profile section.
Pos_No	Prefix and start number for the position number of the plate and in the second row where prefix and start number of the assembly number can be defined. Only used when the gusset plate is not welded.	The default start number of the part is defined in the menu File > Settings > Options.
Material	Material of the L-profile, washers and nuts.	The default material is defined in the File > Settings > Options.
Name	The name displayed in drawings and reports.
Class	The class (color) of the profile.
1	Length of the profile.

UDA tab

Tab UDA can be used to define the UDAs of the parts.

Options	Description
Part	Define which parts do need UDA. The options are: ● No ● Yes
UDA-name	Define the name of the UDA.
Type	Select the type of the UDA. Use String for text, Integer for numbers, Float for numbers having a decimal and Option to use a list. The type of UDA cab be found in objects.inp.
Value	Define the value to be added into a UDA.

In case in tab Picture in the drop-down list Type option Profile has been selected, option in tab UDA can be used to fill the UDAs. Example adding type and article number.

How to add the UDAs:

List Part select Yes.
Type a valid UDA name.
Type to define the valid setting.
Value de wanted text to be available in the UDA.

Example:

In the UDA of the profile, it looks like this:

Also, a list called stud-list is available:
