T-Rivet with of 6.4 mm:
Do not place your hands or the wire harness
within a radius of 20 mm (0.70 in.) from the rivet,
as the rivet is cut and opened in this area.
Prizing a riveter damages the riveter showing
that it is not tightened correctly and bends the
mandrel.
Loose tightening may result from either tilting
the riveter while handling or the riveter not con-
necting to the material.
Loose tightening also occurs when a rivet is ap-
plied between materials without touching.
T-Rivet with 6.4 mm:
When a mandrel of a rivet is lost, the rivet
should be replaced to prevent loose tighten-
ing.

RUST-RESIST ANT SHEET STEEL PARTS
Rust-Resistant Sheet Steel have zinc, tin or aluminum etc, plating over the base metal surface in order to
improve the corrosion resistance of the sheet metal. This sheeting is used on areas that require anticorro-
sive abilities but there is no need to distinguish the differences between rust resistant sheet steel and ordi-
nary sheet steel in body repair.
Body panels on TOYOTA models are made of two different melted galvannealed sheet steel. The ordinary
melted galvannealed sheet has a zinc plating over the base metal surface and when heated a zinc-iron
alloy plating. The zinc-iron double layered galvannealed sheet has a iron rich and another zinc-rich layer
above the sheet steel. These 2 layers improve paint adhesion. These two melted galvannealed sheet steels
are used selectively according to need.

The handling of Rust-Resistant Sheet Steel is the same as for ordinary sheet steel, but the following should
be observed.
1. Panel Welding: The paint as well as the zinc portion must be removed completely from the welding
area to guarantee good welding integrity.
2. Anti-Rust Treatment: Since the zinc plating is lost after welding, anti-rust treatment of the welded area
must be thoroughly performed (refer to section AR).
