Correct period screws for 1960's Maserati

Hoping someone can confirm or otherwise if phillips head screws were ever used on 1960's Italian cars, I've been doing some googling & General Motors were using phillips head screws in the the late 30's, however I can't find if Maserati used them.

I'm preparing my fully restored '67 Sebring Series II for a concours & one of my good friends who is also a judge at numerous events here in Australia, says only straight slot head screws were used on Italian cars back in the '60's, not phillips head which my car has a quantity of phillips head that were used during the restoration.

My friend says you can be marked down for non original type screws, if in period they were straight slot head vs phillips.

 

Thank you for this info, I've also written to Fabio Collina at Maserati Classiche to ask the same question, however sometimes anecdotal evidence such as yours is potentially even better.

 

Thanks but I’m not sure what you’re suggesting with this, I’m looking for what were the original type screws installed by the factory in the 60’s.

 

Thanks for all the comments so far, my car has a mix of straight head & phillips head, here are some photos where there is a difference, my real quandary is whether the phillips head are what would have been used by the factory originally, I'm maybe being too pedantic but my friend seems to think only straight slot were used.

It's very hard to find cars of the 60's that are totally original to compare or haven't been restored, most modern restorations would use phillips head given the ease of tightening these as opposed to straight slot.

See attached a sampling of photos from my car showing phillips & slot head, I'm concerned the phillips used should perhaps be slot head & need changing out for concours originality concerns? There are a lot of trim screws that are phillips & from Heymj73's comments above this may well have been factory original to use phillips. Hopefully Fabio will confirm either way.

The restoration is magnificent see last photo, however these little things in a concours can cause point deductions.

Thanks wilde for your comments & insights as well, I think as you say there are many screws that are new & potentially are not correct, being flat & not domes, interestingly Heymj73 makes mention of his Father's old Ghibli having period phillips for the interior trim, thanks to his comments again also.

I'll wait to hear from Fabio for hopefully a definitive answer & then subject to his advice I'll probably change out some of the phillips where I believe they should have been domed slotted & leave most of the interior trim as phillips.

Thanks for the explanation & source for all screws

 

Thanks for this info, my friend here in Australia also mentioned Newco, I will order from them all the replacement fasteners I need
cheers

Well I heard back from Fabio, he confirmed straight slotted screws were correct, he was not specific about any exceptions & just stated phillips head not correct, it is interesting from comments here there are few definite exceptions ie door hardware.

I'm going to change out all phillips head & potentially just leave some of the door hardware with recessed phillips head as mentioned by lussoman above. Thanks for all the input.

cheers
Peter
