How do you measure Dzus?

Taking measurements of Dzus 

It is correct to measure a Dzus Fastener’s length or grip from the base of the spring locking area to where the head meets the body. For flush heads and self-ejecting Dzus fasteners, the measurement is made from the top of the head to the bottom of the spring locking area.

How to Measure a Dzus Fastener

Dzus Diameter Measurement

Our inventory of Dzus include a variety of diameters. The shaft of a Dzus determines the diameter of the fastener. For an undercut style fastener, the diameter is determined by measuring the widest section of the shaft. The diameter of 7/16′′ Dzus is actually .406′′, not 7/16′′ (.437). BTW The diameter of the fasteners is displayed in fractions of an inch since they are made in the USA. Dzus are most commonly sold in diameters of 5/16″ and 7/16″.

Measurement of Dzus Springs

Springs from Dzus come in three sizes: 3/4″, 1″, and 1-3/8″. The size is determined by the distance between the rivet centers of the spring. As a rule, 3/4″ Dzus Springs are used with 1/4″ diameter Dzus, 1″ Dzus Springs with 5/16″ Dzus, and 1-3/8″ Dzus Springs with 7/16″ Dzus.
