I have a set of T1 spades sitting here on my deask. I measured the inside dimension to be exactly 5/16". There is no way they will go over a 3/8" post without widening the opening somewhat.
From Analysis Plus
T1 Spade
$15 each
Machined from a block of copper & silver plated.
Will fit 1/4"-5/16" binding post.
The T1 is 0.52" wide and 0.10 " thick.
