Two suggestions that work for me.
1. For rangefinders, i use a square Mamiya TLR hood that has a spring metal clamp.I have made a circular insert for the hood that takes non screw- in filters from Kodak.The filters push into the` mouth' of the hood.
2. For SLR lens 52-58mm i use a telescope hood, because of its design it will push onto either diameter lens.
Fortunately no vignetting with either.
Others may have more help, what make of lens and thread diameter?
regards,
CW
