Not necessarily smaller. Just use (for instance) M3.5 instead of imperial (which is smaller) and tap the rhread out (or drill out and glue nut on back). Will work just fine. Electrician would tap the thread. A cheap tap tool can be bought for a few pounds and will last a home owner just fine for infrequent use.
