Details
FJ6-1/2-80 is a Dzus Type FJ quarter-turn stud with a flush head with a long undercut, a 13/32" body diameter, and a .800" working length. Sits flush with the panel surface for exterior skins and cowlings where airflow matters. The long undercut lets the stud stand proud when unlocked.
ABOUT: Dzus fasteners are quarter-turn, self-locking panel fasteners made of heat-treated, cadmium plated nickel steel, used with an aluminum grommet and a music wire spring. The stud passes through the removable panel, the grommet locates and protects the panel hole, and the spring is riveted to the underlying structure where it takes the load and provides the locking action. They are used on covers, plates, cowlings, and similar panels that require quick removal and replacement. Worn, bent, or broken parts must be replaced to maintain clamp load and vibration resistance.

DETAILS: In Dzus nomenclature the leading letters give the head style, the first number is the size family expressed as the body diameter in sixteenths of an inch, and the number after the dash is the working length L in thousandths of an inch. Size 6-1/2 is a 13/32" body, and the -80 suffix is a .800" length. Select the stud length by measuring total thickness from under the stud head to the point of spring attachment, then pick the spring height to match.
