This is how you choose slotted hook bolts of 5.2 x 40 mm

Start with the thickness of the materials you are joining. A length of 40 mm must be able to grip far enough into the underlying wood, while the tip must not come out on the other side. So measure the total thickness of the parts to be fixed and calculate how much wood the screw still grips at the bottom. For delicate wood, you can pre-drill so that the wood does not split.

Working with a slotted head

With a slotted head, it is important that the screwdriver or bit fits well in the slot. If the tool is too narrow or too wide, it slips more easily and the head can be damaged. Place the tool straight in the slot and press firmly while tightening. If you use a cordless screwdriver, set a low speed so that you do not overdrive the screw.
