SME service is terrible. Can’t buy any accessories from local dealers here in USA


Talk about a pain in the … I’m trying to get a basic setup tool for my 309 arm a HTA key to adjust the horizontal tracking. I found out SME doesn’t allow dealers to sell any accessories or parts for their turntables and arms. WTF! This means if you need a common replacement part like belt your looking at 2 weeks for the part to arrive.
Not only that but shipping from the UK isn’t cheap. Who ever at SME made this bone headed decision at SME needs to fired or better yet, something worse!

The HTA key is keyed similarly to a T6 torx.
AFAIK its either a torx or not a torx which is very specific
in design. Add a centre protrusion and its an anti theft torx 
add or take away will call it a finger, and it's another brand
with a different name

Lets all agree manufacturers don't make fasteners and 
anything not made in the U.S. is probably metric 
excluding U.K. built vintage cars and bikes.





 Music Direct has SME parts. Maybe not what you need, but they do sell them. Worth a look.
Vintage British cars use anything but metric fasteners. Typically “Whitworth”, which is their own system of measurement for nuts and bolts. I guess it depends upon how you define “vintage“.
while the UK was a member of the EU, they likely went metric.
