I was browsing Radio Shack and I saw, this motor, and I was wondering if it would provide enough torque to spin a 1.75" long PETG bolt. I also need to figure out a way to make the bolt spin to the sealed position every time I pull the trigger. Finally, is there a way to control how fast the bolt spins and how long it stays in the sealed position?

Perhaps you could use the motor to flip the switch for the actuator. This would allow you to fire in fully automatic mode as well. Attach a wheel to the motor shaft with notches cut into it so that the rotation of the wheel will push the button, let it reset, and then push it down again.

Also, if there will be a load on the "bolt"" (this is an incorrect term, but I know what you mean), then you will need either a higher torque motor or a gear head motor (which has has enough torque to spin no matter what basically). Gear head motors will also solve that free spinning problem, as they lock into place when they stop. Think of a power car window, since that's a typical application for them. However, these types of motors are usually large and less cost effective (if you know what I mean).
To vary speeds, change the voltage to the motor. To vary the voltage you could buy a variety pack of resistors and test them out to what you like, or you could buy an adjustable one. Be aware that Radio Shack stores mostly do not carry electronic pieces anymore, but there are some. If you do end up buying off of the internet, just use allelectronics.com . The shipping is constant no matter how much you buy, and the prices are great, and even better with bulk discounts.
Use a "momentary switch" also if you were wondering which to get.
