These are the correct fasteners for a Piper Warrior II cowl. I have a 1978 model.

Nice effective product. For new installation, you will need springs and retainer split washers.

A well made upgrade for my regular steel 1/4 turn studs. The fit is perfect on these and I couldnt be happier.

The precision measurements I took of my OEM studs were an exact match to these upgraded stainless.

These Southco quarter-turn fasteners make the PERFECT cowl attach method. I used the wing-head fasteners (-12 model) -- easy to install & remove without a tool. And since no tool, GONE are the frustrating, inevitable scratches on the cowl paint near the fasteners caused by tool slips!
