Using Flow Form Rivets
Describes how to use flow form rivets in the repair of Tesla vehicles.
To install the flow form rivets specified in a Tesla structural repair procedure, use the information in this document to perform the following steps:
- Prepare the panels for rivet installation.
- Select an approved riveter and associated dies to install the flow form rivets.
Flow form rivets can also be used as an alternative to self-piercing rivets (SPRs) in any Tesla structural repair procedure that specifies the use of SPRs. This includes situations where there might not be sufficient room for the installation of SPRs because panels have been previously replaced.
To use flow form rivets in place of SPRs, use the information in this document to perform the following steps:
- Select the correct flow form rivet for the thickness of the panel stack.
- Prepare the panels for installation.
- Select an approved riveter and associated dies to install the flow form rivets.
Selecting the Correct Rivet
Perform the steps listed below to determine the correct flow form rivet for a given panel stack.
- Use a caliper to measure the total thickness of the panel stack.
- Use the information in the table
below to find the flow form rivet where the measured thickness of the panel
stack falls within the grip range of the rivet.NoteWhen the measured thickness of the panel stack is within the grip range of two flow form rivets, use the longer rivet.
Flow Form Rivet Grip Range (mm) S08 1.3 – 2.5 S18 2.3 – 3.5 S28 3.35 – 4.10 S38 4.0 – 5.15 S48 5.0 – 6.1 S58 6.0 – 7.2 S68 7.1 – 8.3 NoteRefer to Approved Fasteners and Fastener Tools for Structural Repairs for flow form rivet fastener symbols and part number information.
