If you’re new to DIY or home repairs, one of the most daunting tasks you’ll face is figuring out what hole certain items go in. Whether it’s a screw, nail, bolt or any other type of fastener, understanding where each one goes can seem like a puzzle.
But fear not! Here we’ll simplify the basics and provide you with all the information you need to get started on your next project. From the different types of holes to how to use them effectively, we’ve got you covered!
Types Of Holes
When talking about “holes”, there are two main types that come to mind: pre-drilled holes and pilot holes.
Pre-drilled holes are simply existing holes that have already been drilled into whatever material you’re working with. These are commonly found in furniture pieces where screws will be inserted during assembly.
Pro tip: Make sure that any pre-drilled hole is slightly smaller than the screw diameter for a better grip.
Pilot holes are typically small-diameter holes drilled into wood before inserting screws. They help prevent splitting by guiding screws along their path and reducing resistance created when trying to drive them directly without pilot drilling first.
Fasteners And Their Corresponding Holes
Let’s take a closer look at some common fasteners and where they belong:
Screws can either be self-tapping or non-self-tapping depending on whether they create their threads as they go along or not, respectively. For both types of screws, it’s important to understand which hole should be used:
- Sheet Metal Screws: These require no prior drilling; instead, they self tap into thin metal sheets due to their sharp tips.
- Wood Screws: For wood projects ensure a ‘pilot’ hole be made. This hole should have a diameter slightly less than the diameter of the screw’s shank – this helps prevent splitting.
- Drywall Screws: These require no prior drilling and come in handy for wall repairs or fixing things to walls, especially drywall.
Nails are another common fastener used in DIY projects, and there is only one type of hole that they fit into:
- Without pilot holes: Nails get hammered directly into wood or any other soft material with full force until flush with the surface. No prior preparation required here!
Bolts are similar to screws but typically longer and thicker. They also anchor two or more sections of material together for maximum support. The corresponding hole required depends on how it will be fitted:
- Un-threaded bolts: A nut will be threaded onto an un-threaded bolt so ensure beforehand that both items correspond correctly by way of length and width .
- Threaded bolts : To fit framework pieces together drill a ‘through-hole’ through which threaded bolts can pass through when joined.
Top Tips For Hole Drilling
Drilling flat surfaces can prove tricky, making them harder to maintain balance as you try set your drill straight throughout the process.
Pro tip: Before drilling on a flat surface use masking tape; stick some directly over where you plan to make the hole before marking it up using an awl-like tool such as a center punch).
For tougher materials like metal plates, aluminium sheets, hardwoods e. t. c. , lubricating oil is recommended when drilling pilot holes to assist with smooth performance during insertion.
It’s important not to go beyond hardness limits specified linked-to all types of non-metallic materials-limits printed on product labels as these may damage/dull drills bits causing future tasks/engagements with these tools even more difficult.
Here are some common mistakes you should avoid when drilling holes:
- Not measuring accurately – take extra time to double-check measurements, otherwise, the end product may not align well with specifications.
- Over-drilling or under-drilling holes can lead to instability which in turn increases chance of damage through movement so ensure you get your hole positioning correct!
- Using dull drill bits leads to a lot of frustration and partly screwed fasteners at the end of the project. Always make sure sharp/undamaged ones are used.
Q: How do I know what size drill bit to use for my pilot hole?
A: The size of your pilot hole is determined by the diameter of your screw shank . Usually, a 1/16″ smaller than the screw’s shank is sufficient as explained earlier in this article
Q: Can I simply hammer screws into wood without drilling?
A: You’ll regret trying! Screws that have no pilot-hole will most likely split wooden surfaces, particularly along grain patterns that provide weak points for impact energy transmission.
We hope this article has given you a better understanding of “what hole does it go in?”, whether working with nails, screws or bolts. Don’t forget proper preparation before installation contributes significantly towards ensuring durability/stability throughout usage seasons. Keep calm while drilling even on challenging surfaces as an intentionalistic hand goes along way:)!.
