The shell head of the extrusion rivet (also known as the seahorse rivet) is formed by extrusion processing, so it is called. It has high tensile strength, high shear resistance, and high anti-loosening performance. According to the material and head type, there are all-steel, all-aluminum, round head, flat head and other types.

The main feature is that the rivet core has a locking groove structure design and is subjected to enhanced heat treatment. After riveting, it has high shear resistance and nail head retention performance, and has high strength and anti-loosening installation characteristics.

Usage scenarios

BSL® blind rivets are divided into ordinary connection strength rivets and high-strength structural rivets.

Ordinary open rivets are used in ordinary connection strength occasions and are applied in many industries.

Structural rivets are a series of special rivets that enhance the structural connection strength between plates.

In order to adapt to different material requirements, connection strength requirements, and surface protection requirements, the following lists the recommended types of blind rivets.

Surface treatment

Surface protection depends on the product material and installation environment requirements. The recommended rivet shell material grades and protection types are as follows:

00001 Note: * This manual does not include blind rivets made of copper and copper-nickel alloy. If necessary, please consult with Bosch R&D and engineering personnel.

00002 Note: ** Material SCM435 is mainly used for the core of ring groove rivets, which is the main connection carrier that bears high tensile and high shear resistance.

1.1 Product installation steps

1) Select a pneumatic or battery-powered rivet gun with matching pulling force, install a nozzle with matching diameter specifications, and adjust the appropriate rivet stroke according to the installation thickness and tool manual;

2) Load the product and perform an empty pull test;

3) Perform a real rivet test on the test sheet metal, as shown in step 1 below.

4) Observe whether the clamping state of the product is normal after installation.

5) (To determine whether the installation fails, please refer to the following article – Product installation failure mode pictures)

1.2 Operation steps

Hold the product or the nozzle close to the tail of the rivet to automatically suck in the nail core and the rivet flange surface to ensure that it is close to the nozzle. Insert the tool into the installation hole in a direction perpendicular to the sheet metal plane and close to the sheet metal surface, then pull the trigger to start riveting until the nail core breaks. At this time, one riveting action ends, and then the next working cycle is carried out.
