MS20426AD-6-5 specifies a countersunk rivet with what overall length?

The designator MS20426AD-6-5 provides specific information about the characteristics of the rivet, where the "6" in the designation represents the diameter in 32nds of an inch. Therefore, "6" indicates a rivet diameter of 6 times 1/32 inch, which equals 3/16 inch.

The last part of the designation, “5”, indicates the overall length of the rivet. In this case, the length is specified in 1/16-inch increments. Thus, a "5" means the overall length is 5 times 1/16 inch, which equals 5/16 inch.

This means that MS20426AD-6-5 consistently refers to a countersunk rivet with an overall length of 5/16 inch. Understanding these designations is essential for selecting the correct rivet for applications, ensuring structural integrity and compatibility in sheet metal assemblies.
