Most US 45's are just left LH die-cut and yes a LH adaptor or LH cone adaptor are normally used on turntables only autoplayers or multi-functional turntables like a Garrard would have a stack post.
The USA record 45 rpm adaptors were invented on a remit from David Sarnhoff @ RCA so that all US 45's could now play on a standard small spindle auto changer for 12" amd 10" the adaptors have three protruding lugs or nipples and these are called driving pins and do the same function as our UK anti slip ridges do. the Pins interlock against each other to help prevent the smooth records from slipping when on an autoghanger.
The adaptors do not have enough force to stay in place and so the legs have to be bent (carefully) to make the leg longer and grip the die-cut edges.
These USA adaptors are enot spiders and are not called spiders. They are RCA- 45 rpm adaptors.
The 45 rpm adaptors that were designed and manufactured by Phonogram when they went over to LH Die-cut pressings late 1960's these were superior to the USA ones in that they had and kept a tight grip aand did not dislodge or fall out easily and it is these not unlike a letter Y that are spiders and were called spiders by Phonogram and we had to fit them as retailers to every die-cut LH 45 we sold.
Phonogram supplied them in bags with the boxes of singles The first UK die cut LH that I recall both seeing and then having to fit a spiders to was Dave Dee Dozey etc Legend Of Zanadu Fontana, (I managed to get a 3 pin dinked copy for myself).
The USA adaptors are called 45 rpm adaptors circa 1950 (world wide)
The UK adaptors from Phonogram circa 1968 (manditory UK then available pan Europe) are called Spiders
Spiders should never be fitted to USA Canadian Japan or Jamacian 45's
Spiders should be fitted to all UK die-cut LH's from 1968 to 1986 when they ceased production by Pollygram.. Naturally the USA adaptors came back on to the UK.for die-cuts.
There has been a serious resergence of LH die-cut 7" here in the UK and naturally the USA 45 rpm adaptors go with these.and come in a serious range of colours and are I have to say iconic, where the Phonogram Spiders are not and never have been!
I really don't know if LH die-cut scans look better with or without it's appropiate applicable adaptor inserted. I like the look of them in personally as I also seriously prefer 4 or 3 pin dinked 45's over un-dinked or small hole SH. ( I find the term "sold centre" rather silly as it implies there is no hole at all ie it's solid, or that IMHO indeed the record should have had a hole (or two) either in the middle of a 3 or 4 pin dinked copy or just a die-cut LH very much each to his or her own I guess)
I think we did the terminology but hey-ho we are still getting press-outs push-out centres solid centres dinked where the record scanned is clearly a LH die-cut and so on,
I can only state how it is industry-wise and factually a die-cut is just that a die-cut large hole 1 1/2" as are the 3" holes in generic sleeves they are called die-cut die-cut sleeves (not dinked sleeves)
Dinked records are not strictly die-cut persay as the blade and block are shaped to cut-out - dink specific areas to leave a fixed area that then looks like a 3 or 4 pin centre round or tri-angle (3 pin) and thus the centre has been dinked (specific areas cut-out removed dinked) and originally refered to as an "Optionl Centre" OC as it can be removed) die-cut would be a complete circle or hole there is nothing dinked on there as the whole area of 1 1/2" has been? DIE-CUT
I really hope this helps one and all and makes it simple and clear. and we can leave the wrong or miss informed terminology where it belongs on wikkapedia or even better in the bin>

Some old answers from a vinyl site practice on junk records before attempting to take these out of something valuable. you can easily crack a 50s brittle 45.
1.Sort of a trick, I guess. I don't know, I just seem to be able to do it fairly effortlessly now, whereas in the beginning those things would drive me crazy trying to get them out. The way I do it is to use some light pressure near one of the "spokes", pressing in towards the record, which putting some pressure on the flip side on an opposing spoke. With trial and error, you'll get it, but one thing is for sure - it's not a brute force thing (we've all seen the results of that approach).
2. I never have a problem getting these out but it comes with a bit of practice.
What I do is bend the record, and while it is bent place my thumbs on the adaptor and apply enough pressure to force it to move up, down or sideways. Once it moves a touch, you're home.
You will be surprised at how much you can bend a record without snapping it, but don't go crazy! You'll see the fruits of this method quickly.
