Very difficult to determine correct size from Spruce catalog. I ordered several examples and went by trial and error. The size on the old part is frequently unreadable.

I ordered the wrong size. The ones I got were too small so I sent them back with one of mine here so you could personally match it. I mailed it last Monday Alan

Ordered wrong ones,returned them and ordered correct ones. No problems ,happy customer.

Camloc worked like a charm for replacing the one I misplaced.

Be aware the measurement from the top of the faster head to the horizontal part that does the fastening is somewhat ambiguous. The diagram could be more clear as to this distance on each part. I ended up ordering six different pieces before I got the correct Camloc since I was guessing. The Camloc functions perfectly now that I have the correct size.

Great fasteners. Do the job with easy release.

Great service !

Fit my C182p cowl perfectly.

Worked perfect. These were used on a Mooney 231 cowling. The -4 are used on all attachments except rear mist which are -7.

Like the Camlocs. Dont love the price. My experience with the Aircraft Spruce service side has always been good.

Sizing is confusing, I thought i was ordering a 3/4 stud but received a 5/8 this stud is 1/8 too short and will not lock the cowling. Returned the 2 studs with drawings and dimensions, Have not received reply yet.

On these quarter-turn fasteners 2700-x, the last digit, the x is embossed into the top of the fastener, the top of the screw-head. I, like many others no doubt, lost one of my fasteners, and wasted time, $, and effort trying to determine the correct size. Please make mention of this fact in your description, for the benefit of others!

Good news/ bad news: The good news is that the 27S3-2 faster fits my 182 cowl well. The bad news is that the catalog info was poor and I had to order 4 different sizes in order to understand the sizing system. Also ordered both kinds of lock washers for the same reason.
