The common question regarding the screws needed for stainless steel inserts (Binding Freedom & Quiver Killers have the same threads) and particular bindings
hopefully can be answered here. It is impossible for us to remain on top of every screw for every binding and there are variables that can be at play depending on your particular set of circumstances (ie, insert installation depth, shims, binding thickness, etc).
Measuring your binding thickness and adding that to your insert depth is your best guide.
Ordering more screws than you think you’ll need is always a good idea. Also, you can always reduce the length of screws that are a little long. If in doubt, erring towards longer screws with the possibility of minor modifications by grinding or filing allows some flexibility.
Using a threadlocker like Vibra-Tite is highly recommended.
Binding Freedom has a Screw Length Chart that will be updated from time to time, along with the following screw measuring tips and images.
Tips on Measuring your bindings for screw lengths
Flathead and Smallhead screws are measured as the total length of the screw, while Buttonhead screws are measured as the length of just the threadsFasteners should protrude 4mm MIN and 6mm MAX into a threaded insert. To determine the idea fastener length, press an existing screw into the binding hole. Make sure it has bottomed out in its hole. Measure how far it protrudes below the base of the binding.Measure the screw itself as well. Subtract the protrusion length from the length of the screw. Add 5mm to that length. Find the closest size fastener that is within 1mm of that number. In this example, 13mm – 9mm + 5mm = 9mm. Either an 8mm or 10mm flathead would be appropriate for this binding.
