Lewmar portlight replacement domed rivnut

[IanR]

Looking to rebed my old fixed portlights which have closed head domed / coned heads.

All of the suppliers on the web seem to have open heads or be closed at the other end of the thread, could anyone direct me to a direct m4 m5 replacement please?

Going to replace them all as some are spinning which makes the job difficult to say the least

Cheers

Are you really looking for a "rivnut"? Or maybe you want interscrews?

Just perfect, I have been looking for a week and you guys have just saved me.
Amazing how sometimes google is so literal

I guess they are called Interscrews because of the pricing model- eek

thanks to both of you

Supply and demand! Believe it or not, some people refer to interscrews by the alternative name "sex bolts".

A much cheaper alternative is to use ordinary machine screws and domed head nuts. The nuts are bulkier than interscrews, but you can get a pack of 20 M4s for £1 on Amazon.

Being a total tightwad, that's what I used on my windows, and the Admiral thinks they look good. (My opinion is, of course, irrelevant )
