I’ve looked and I’m stumped. My 182 top cowl has all but 1 fastener that is a Camloc -4 with a slotted head (captured to avoid driver slippage and paint scratches). The odd fastener is the one pictured below. It says M 8 and is Phillips. The receptacle is a also different depth, so none of the Camloc -4s can grab the receptacle. I want to replace the one odd fastener with a slotted one (because either (a) my plane is going to fall out of the sky, does not fly straight without it, and is unworthy of admiration, or (b) the pilot is screwy...not sure which). Does anyone know who makes this, or where I can get a captured slotted head? I will pay a stupidly ridiculous ransom, trust me.
