1/8 " X 1/4 " Pop Rivet Solid Aluminium Countersunk Rivets DIN7337 Stainless Steel
1. Descriptions:
Blind rivets are mainly used when access to the base material is available from only one side. There are many applications where the back of the base material cannot be accessed, as in fastening to walls or tubes. In cases where the back or “blind” side of the material cannot be reached, it is not feasible to use sheet metal screws, nuts and bolts, or welds. Even the use of solid rivets requires access to the rear of the base material. Blind rivets form a very valuable function in these applications, and can be extremely cost effective.
Cost is a major reason why a manufacturer might choose to use a blind rivet in an application. The unit cost of blind rivets is much lower than the cost of most other types of fasteners. The labor cost savings is equally impressive, because they can be installed at a rate of up to 15 rivets per minute. Try matching that speed with a nut/bolt installation!
The typical governing factors in rivet material selection are strength, corrosion resistance and the material to be fastened.
Galvanic corrosion, also called “dissimilar metal corrosion” refers to corrosion damage induced when two dissimilar materials are coupled in a corrosive electrolyte (e.g. water). Certain materials should never be in direct contact with one another (like copper and aluminum), because a galvanic action will corrode one metal at a faster rate than the other. Galvanic corrosion is of particular concern in applications that are high in moisture content, like air conditioning and marine applications.
To assist in corrosion prevention, these rivets have a completely closed end to prevent the entry of liquids, moisture, air and other contaminants into the rivet or the riveted hole. Likewise, this rivet can be used to prevent the leakage of such materials from an assembly.

4. Applications:
The rivet assembly is inserted into a hole drilled through the parts to be joined and a specially designed tool is used to draw the mandrel into the rivet.
This expands the blind end of the rivet and then the mandrel snaps off.
These types of blind rivets
have non-locking mandrels and are sometimes avoided for critical
structural joints because the mandrels may fall out, due to
vibration or other reasons, leaving a hollow rivet that has a lower
load-carrying capability than solid rivets.
The blind rivets are mainly
used when access to the joint is only available from one side.
