screw for attachement assistance

this is not exactly wood.. but i figured since yall are finishers you came across this before.. i am installing old galvalum roof panels on the ceiling of a porch. (see attached picture). i know when there installed as a roof panel we use those neoprene washer self tapping screws... but what do you suggest to use as a ceiling panel on a log cabin porch ? (attaching to wood trusses at 24" o.c.). The logs are a darker brown. hopefully the screw is something i can get at the local hardware store, but will order online if i its a better choice.

the little guy in the pic is my helper!

thanks for the help!

I modified a wood framed carport and attached corrugated metal roof panels using hex head self-drilling screws with the rubber washers under the head (see johnep's link above). Just chuck a socket in a drill and drill away.

The rubber washers aren't needed if it is going to be under a roof, check the big boxes for "truss" headed screws they also call them lath screws, they have a good sized washer head

Or you could use 1" Malco Zipin sheet metal screws like I did about 25 years ago, they have 1/4 hex heads like the washers screws but are about 1/10 the price
