Several -# used around the cowling, difficult to determine which -# to order. I guessed -3 and it came out OK, but probably better to order the next lower (-2). Dont understand why the -2 is about 3x the cost of -3.

The F Verified Purchase

40S5-3S Stainless Steel Camloc Phil Stud

Very fast response and delivery of product.

Good quality. Work as advertised.

Great product.

The GAMI GPS antenna is an approved antenna for ADS-B or other Aviation uses. C-190 and recommended by the ADS-B in and out manufacturer I used. In testing the antenna works very well

As expected, on time, and the right part

Exactly what I needed.

Good quality stainless steel fasteners the guys are swapping out from the zinc coated on the aircraft.

I just replaced the old slotted-head camlocks on an Aztec with the new style slotted. The slotted pocket makes me worry less about the screwdriver slipping out and gouging the cowl. A very easy upgrade!

After 7 years in service in the cowl of my 182, I am finding I have to replace some of the stainless steel camlocs because the locking pin through the end of the stud has come loose. The pin then migrates, which causes problems - they wont lock, or worse yet you cant unlock them and your cowl is stuck on the plane. My A&P tells me this is a common issue with stainless camlocs and I should have bought the steel ones. Well, I like the look of the stainless ones too much for that so I purchased a stock of replacements and a pair of camloc pliers, and now I can replace them as they turn up loose. 5 so far. At least they are easy to replace (if you have the pliers), and I still like the shiny and corrosion-free looks of them.
