HOW THEY WORK!

A Blind Rivet consists of two parts: the rivet body and, within it, the setting mandrel.

1. The Blind Rivet body is inserted in a hole in the materials to be joined.

2. The Blind Rivet tool is placed over the mandrel. The tool is actuated and the jaws of the tool grip the mandrel.

3. The jaws retract, extracting the mandrel which pulls the mandrel head into the rivet body setting the rivet. At a predetermined tensile load, the mandrel breaks from its head and is discarded.

This forms a strong, tight, reliable joint. Because this is all done from one side these are called BLIND rivets.

DESIGN GUIDELINES

Channel Material

(A) If the nose housing of the tool is too large in diameter to reach the bottom of a channel, use a long nosepiece on the tool. A rivet with an extra long mandrel may be required.
(B) Install the rivet from the opposite side.

1

Gap Fastening

(A) Avoid riveting unsupported internal sections which may result in collapsing, dimpling or buckling the material.

(B) Select supported sections for best success.

2

Pivot Fastening

When the fastened part must rotate on the rivet, a “pivot style” nosepiece on the rivet tool may be necessary to provide a small gap under the rivet head.

3

Fastening in a Blind Hole

盲铆钉可以设置在盲孔或铣削槽中。这取决于要铆接的部件的材料和铆钉的材料。将需要测试。

4

Riveting Plastic Material

Select:
(A) “Soft Set” aluminum rivets,
(B) Large Flange style rivets
(C) “Tri-Grip” rivets.

5

Hard to Soft Materials

The following illustration is a guide for using standard blind rivets to fasten hard materials to soft materials. Other options are to use Groove Rivets or T-Lok Rivets.

6

Edge Distance

We recommend 2 times the rivet body diameter (D) or more from the center of the rivet to the edge of the work piece to avoid material fracture.
