GE1996T Stud Lock System
The components of this system are the GE1996T Stud, Anchor and Stud-Lock Screw. According to the Gotoh GE1996T Operation Manual, the Stud Lock System increases "the solidity of the anchor and stud combination." This, in turn, will enhance "the vibrational tone transfer from the strings to the guitar body." Now, since the actual mechanics of this system will be detailed later, I thought it best to begin this post by examining a GE1996T Stud and Anchor.
GE1996T Stud and Anchor - Overview
The first image below is a diagram of the GE1996T Stud and Anchor as shown in the manual, with dimensions in millimetres. But what about the "M8" label below the GE1996T Stud? I was wondering about that, and decided to do some research. As it turns out, the letter 'M' indicates that the stud uses a metric thread, while the number '8' refers to the "nominal diameter" of the stud shaft in millimeters. In plain English, this means that the outer diameter of the GE1996T Stud is 8mm.

GE1996T Stud and Anchor - Basic Operation
In the simplest of terms, the anchors are embedded in the body of the guitar, and provide a secure location for the studs to be screwed into. The studs, meanwhile, act as height-adjustable pivot points for the two knife edges of the Tremolo Base Plate. The height of a stud may be adjusted using the supplied 3.2mm hex wrench. Clockwise screws the stud in, reducing its height; while anti-clockwise does the exact opposite. In the images below, you can see how a GE1996T Stud may be unscrewed completely using the 3.2mm hex wrench.

GE1996T Stud-Lock Screw
The Stud-Lock Screw is housed at the base of the GE1996T Stud, and features an anodized black finish. It may be set flush with the base, or extended by a certain amount. This adjustment is effected using the supplied 1.5mm hex wrench. Clockwise screws it out of the base, and anti-clockwise pulls it back in. The main function of this screw is "to press against the anchor bottom, tightening the contact between stud and anchor threads." Gotoh asserts that the Stud-Lock Screw will prevent the GE1996T Stud from shifting while in use. Now, let's look at this "special" screw.

Locking the GE1996T Stud in Place
In this final section, we walk through the steps taken to lock the GE1996T Stud in place inside the GE1996T Anchor; as described in the manual.
First, insert the 1.5mm hex key (4) into the center of the stud (1) and twist clockwise slightly to make sure the Stud-Lock Screw (2) is loose enough to turn easily.
Then, insert the stud (1) into the anchor (3) and then use the 3.2mm hex key (not shown) in the head of the stud to adjust it to the desired height.
Following this, once again insert the 1.5mm hex key (4) into the center of the stud (1) and tighten until the Stud-Lock Screw (2) touches the bottom of the anchor (3).
Finally, tighten the Stud-Lock Screw more firmly to make sure that the stud doesn't move.
