Locking T-Nuts are a total game changer. No longer do you need to mess about fishing around trying to place the T-Nuts in the correct position in your foil box. Simply put them in position once, tighten up the M4 grub screw, and away you go. They will always be in the same place for every session and it will stop you from loosing/leaving them in weird places.
Please note that the M4 locking screw does not need to be done up tight. It simply holds the track nut in position, so just tighten enough to lock it in place and no more. If you over tighten it could damage your board, and we do not want that!
Available in M6 and M8 sizes. SOLD AS A SET OF 4
