When a crate repair is small, it is tempting to grab the nearest drill bit and get on with it. That works until the screw splits the end of a slat, wobbles in an old hole, or pulls a handle block slightly out of line.
A simple sample block can take the guesswork out. Keep one straight offcut near the bench, preferably close to the same thickness as the parts you repair most often. Mark it as the test block so it does not get swept into the scrap bin by mistake.
Before touching the crate, drill two or three pilot holes in the sample block and drive the screws you plan to use. The right hole should let the screw bite firmly without forcing the wood apart. If the screw sinks too easily, step down a bit size; if the block starts to crack, step up or choose a shorter fastener.
This is especially useful near corners, dividers and handle blocks, where the wood may already have stress from old fasteners. Testing first also helps when you are mixing reclaimed pieces, because one slat can be softer or drier than the next.
Write the winning bit size on the block with pencil. Over time, the block becomes a quick shop reference for common screws, small hinges, crate handles and light-duty repairs. It is not a formal chart, just a practical memory aid with real holes in real wood.
Practical takeaway: test the pilot hole in a scrap block before drilling the crate, then use the best bit-and-screw pairing on the repair itself. A two-minute test can prevent split slats and loose hardware.
