The wrench is designed to torque just to ensure you do not strip out the treads on the screws. During one of the recent golf telecasts the camera caught, I think Justin Thomas, checking his before going to the first tee. I have never thought about making sure they were not loose and in theory, there should never be a reason for them to loosen up but it might be a good practice when I do a thorough cleaning (usually after 10 or so rounds) just to check them. It could have been that he adjusted the settings earlier that day and was doing a quick check or maybe because when you play for $$$$$$ you don’t take anything for chance.

Not very often. I can't remember HAVING to re-torque any Titleist Driver or wood...or hybrid, since the 910 line was introduced. And I have played virtually every driver, fw and hybrid model since then. If yours comes loose regularly, I would either try using a different Titleist torque wrench (maybe the one you are using is defective), or add a little light grease to the threads of the attachment screw that goes into the shaft. If neither works, I would contact Titleist Customer Support for additional direction.

Just one thought. And I only mention it because it happened to me in a proshop a few years back. I was changing the loft and lie on a Titleist demo wood one day to try it out on the range. As I tightened it and got it just about to its max, the assistant pro said, "That's good," before I got to the two clicks. But I went I continued on tightening until the tool clicked twice. He winced and thought the screw had stripped out. I had to explain to him that's how torque wrenches work. Two-clicks = properly torqued. He had no idea!

So, I'm certainly not implying that YOU don't understand how to use a t-wrench. I am only mentioning that anecdote just in case. Call me Captain Obvious and please forgive me.

Oh, and just to add, the rubber seal is the key. If the rubber seal comes off and isn't replaced or the rubber gets old and bad, you loose the gasket effect and the screws can loosen. I have been in the military technical publications business for 40+ years and most critical bolts and fasteners have periodic checks and some even use safety wire to ensure they cannot come off. It does not mean they are defective, just a natural affect to constant vibration.

Great Advance Guys Thanks Very Much

Whenever the weather changes by 10 degrees or so and at every range session

I've never looked at the settings prior to play. It may not be a bad idea to give them a check as you would not be allowed to "tighten"/correct after play begins for the day (tournament).

Once I set it and click it once to ensure it is tight, guess I figure all is well... I will twist the head every now and then.
If you torque that screw more than one click you can strip the threads. Advice given to me when I purchased my first driver by Titleist fitter.

Well Chuck, obviously that person never worked in a machine shop. The point of the Titleist torque wrench is that it gives way after an established amount of pressure. That clicking you hear is the internal gear in the wrench slipping so the extra foot pounds are not going to the screw. You can click it all day and the pressure will not increase and the screw will not be affected. People should not be worried about over-tightening unless they use something besides a Titleist torque wrench. I have been writing military tech manuals for 40+ years telling technicians how to torque bolts on fighter jets.

I tighten mine every other week. I have found that they do back off a bit every now and then. As has been mentioned the Titleist supplied wrench is designed to not allow you to over-tighten the bolt. As soon as the wrench clicks, the bolt is properly tightened. It doesn't matter how much more you try to tighten the bolt, the wrench will just keep clicking and not further tighten the bolt.
