1) The main installation feature of blind rivets is that the hole must be slightly larger than the diameter of the nail rod so that the expanded part of the nail rod can be inserted.

Different sizes of stainless steel blind rivets should have corresponding riveting holes, otherwise they will loosen. Generally, the hole diameter should be 0.1-0.2mm larger than the diameter of the blind rivet. If it is larger than 0.2mm, it may loosen.

2) The anti-slip pattern on The nail core head rod is mainly for the pulling mechanism inside the rivet gun to better hold The nail core head, so The nail core head with anti-slip pattern is better than The nail core head without anti-slip pattern. However, from the actual use, as long as The nail core head can be pulled off normally, the assembly of the rivet with or without anti-slip pattern has little effect. Because with or without anti-slip pattern, the breaking point of The nail core head is there, no increase or decrease!

3) In blind rivet connection, if the standard electrode potential difference between the two contacting materials is large (such as the contact between the aluminum nail body and the steel plate or the contact between the aluminum nail body and the steel nail core), serious electrochemical corrosion will occur. The solution to this problem is to choose appropriate rivet coatings or take appropriate isolation measures between the connecting parts, such as adding gaskets, painting, and applying protective glue. Under normal circumstances, when the standard electrode potential difference between the two materials does not exceed 0.5V, they can be safely in contact.

4) In some parts related to the safety of product operation, such as some parts of engines, motors or gas turbines, or parts of electrical products where short circuits may cause serious accidents, if individual parts of the blind rivets are damaged (such as the residual core in the rivet body, which falls off under intense impact and vibration), the residues may fall into the running mechanism, then blind rivets should not be used for connection.
