Aircraft Undercut Retainable Studs

The SKAJ series for oval head studs and the SKFJ series for flush head studs allow for the installation of either a crimp style retaining grommet (aircraft applications) or a thin, nylon retaining ring to secure the fastener in the panel or cowling when unlocked. Crimp grommets also prevent enlargement of the panel hole caused by vibration.

Standard line sizes: 3, 4, 5, 6 and 6.5 stud lengths vary by .050". Most common lengths are in stock in heat treated steel and stainless.

Racing Buttons (Non Retainable)

These plain fasteners are available in two basic styles. The SKFO (flat head) series, and the SKAO (oval head) series. This style allows the stud to be completely removed from the panel when unlocked. Standard line sizes 5 and 6, stud lengths vary by .050". Most common lengths are in stock in hardened steel or 7075 high strength aluminum.

Racing Buttons (Retainable) - 7075 Aluminum Button

SKYBOLT Aluminum Buttons are as strong as our steel buttons (guaranteed)! (You break one of our buttons, we'll replace it….they are that strong!) Our unique head design is milled vs saw cut to allow maximum torque with an ordinary screwdriver. You do not need specialized tools that are never handy when you really need them. The slot is walled to prevent any standard screwdriver from slipping or scapping paint. No need for Allen head designs or tools that are never
available when you need them the most. Yet a standard quarter will lock or
unlock any SKYBOLT Aluminum stud.

SKYBOLT Aluminum studs feature a slight undercut to attach an inexpensive nylon washer to retain the stud in the panel when unlocked. This feature is a great alternative to more expensive "Ejector" studs that have the retaining feature. What a concept! Take the panel off and put it right back on without chasing studs! The washer can be easily removed when needed.

Once you use the SKYBOLT Aluminum buttons, you will see, these parts are as strong as steel, you need only a standard screwdriver, you won't scrape paint, and the studs remain with the panel (not in the dirt) ready for instant installation.

Of course, if you like the extra weight, and you take great pride in owning a special locking tool, and searching for studs in the dark adds to your excitement level, Skybolt stocks the standard steel buttons with the sawed, curved slot at very competitive prices!

Ejector Head Fasteners

Ejector head fasteners provide 1/4 turn action with studs that eject from the receptacle when unlocked. Ejected studs 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 heat treated carbon steel. Standard line sizes 5 and 6. Stud lengths vary by .050", most common lengths are in stock in hardened steel.

Z-Loc Weld Tabs & Springs

All plain #5 SkyBolt studs use weld tab part number SK945 (if required) and 5 series S spring receptacles. Both have 1" rivet spacing. All plain #6 series SkyBolt studs use weld tab part number SK946 (if required) and 6 series S spring receptacles.

NOTE: For the SKEHF5 series use weld tab part number SK945EHF and 5 series
S spring receptacles. For the SKEHF6 series use either weld tab part number SK946 and 6 series S spring receptacles.

Airloc® Fasteners

This type of 1/4 turn fastener is commonly used in Beech aircraft. They are available in countersunk or oval head styles. They use a crimp style grommet to prevent panel wear and are retained by a pressed in cross pin. Most simple replacements do not require removal of the grommet. standard line sizes 2 and 5. Stud lengths vary by .010", most common lengths are in stock in steel or stainless.

AIRLOC INSTALLATION TIP:

To Remove Pin: Clip or grind pin to remove old stud from panel.
To Insert Pin: Notch upper jaw of a standard vise grip plier for a handy, inexpensive tool to install AIRLOC® pin. With new stud in panel, press pin into stud shank
