Dzus/Milspec Fasteners

Z-Lock (Dzus type) fasteners come in many sizes and styles.

AJ Series

The AJ series has an oval head with an undercut which allows for the installation of a stud retainer.

Aircraft style studs insure that the fastener stays with the panel when unlocked. A simple groove under the head allows  for the installation of several types of retainers. Full (flare type) grommet retainers protect the panel hole from enlargement due to vibration while also retaining the stud in the outer panel if required.

MSA065 Series 

The MSA Series has no undercut and is available in steel or aluminum.

Motor Sports Racing style fasteners insure that the stud can be completely removed from the panel when unlocked which can be an advantage with sliding or curved panels. Unlike undercut studs, these Do Not have a groove under the head for a retainer.

EHF5 Series

Ejector fasteners provide 1/4 turn action with studs that eject from the receptacle when unlocked. They will not hang up when sliding or curved panels are removed and give a visual sign of an unlocked fastener. The stud assembly is mounted directly to the outside panel with 1/8" rivets or screws. Made from steel with bright Silver zinc or Gold zinc plating.

Spring Receiver

Receiver spring available in 1" or 13/8" center to center. 

Weld on light weight steel receiver spring chassis tabs to suit both options.
