The string is fastened to the other end of the lever, and tightening the screw tightens the string.

The problem experienced here is that you either turn the pegs just a little too high or a little too low, but never right on. To solve this problem, many beginners add violin fine tuners to the tailpiece to assist in fine tuning. Below are some of them made by Wittner and are all metal. There are basically two basic types - one for ball end strings, the other for loop ends. For the ball end type, there is a slot where the violin string fits into. Two posts on other side hold the ball in place (see photos below). In the case of the loop end, a single post holds the loop of the violin string in place . Ball End Tuners Loop End Tuners Some Good Things to Know The ball end tuners are more common than the loop ends, because most strings come with ball ends. However it is possible with some brands of violin strings where the ball can be removed to have a loop end. Don't use loop end strings on ball end tuners Although it is possible to put a loop end string using a ball end tuner, it's not recommended, because the sharp edges of the tuner posts increases the chance of the loop ends to break, as shown on the right. Ball End Tuners (not recommended for loop ends) Some have correctly observed that the post belonging to the loop end tuners also have sharp edges. To solve this problem, Wittner offers a slip-on string protector to go over the post as shown in the right photo. E-string slip-on string protectors (Set of 8 protectors) Hill Model Fine Tuner with single protector More experienced violinist know that adding fine tuners add weight to the tailpiece and change the string length, both of which can effect the quality of the sound. The ball end tuners (about 5 grams) are heavier than the loop end tuners (about 4 grams). The ball end tuners shorten the string's length by about 1 cm. But... Don't worry. Most people are unable to notice the difference in sound. For beginners learning how to tune a violin, these fine tuners are a great way to start off.

Installing Violin Fine Tuners To install fine tuners to your tailpiece, follow the instructions and photos for both ball and loop end types as shown below. Step 1 You'll have to unscrew both the tuning and mounting screws off the tuners. You will have three parts as shown on the right. Step 2 Place the base part containing the screw barrel (the part that the tuning screw goes into) into the one of the tailpiece holes from underneath as shown on the right. Then, take the circular mounting screw and fasten the base in place. Do not over tighten. Step 3 Attach the tuning screw back into the base, but do not screw in all the way, leaving about half the threading in view. Now you are ready to install your string type. Step 4 - For ball-end fine tuners If you are using ball-end fine tuners make sure that the ball is inserted vertically and not horizontally to prevent string fatigue against the tuner's metal edge. Using Violin Fine Tuners Fine tuners only make sense when eliminating the remaining small pitch differences between your violin and the reference tones. Therefore the pegs should do most of the work to get the sound of your violin as close as possible to the reference. However, most people try to use their tuners to cover great pitch differences. It is common to find the tuning screw tight all the way down to the bottom in an attempt to increase the pitch. If this happens, simply use your pegs to tune a little higher than the reference tone if you need to loosen the tuning screw If you find the tuning screw too high (almost falling out), simply tune with pegs a little lower than the reference before you tighten the screw.

Tuning mechanisms for stringed instruments
Screw-and-lever tuners.
Fine tuners are used on the tailpiece of some stringed instruments, as a supplement to the tapered pegs at the other end. Tapered pegs are harder to use to make small adjustments to pitch. 
 Fine tuners are not geared. They have a screw with a knurled head, whose lower end advances against one end of a lever with a right-angle bend in it.
