How to Use a Flat Head Screwdriver
Choosing the Right Screwdriver
Before using a flat head screwdriver, it’s crucial to select the right tool for the job. Consider the location and space constraints where you’ll be working. For tight spaces, opt for a screwdriver with a shorter shaft. For deep or hard-to-reach areas, a long-shaft screwdriver is more suitable.
Additionally, consider the handle material. Soft, padded handles provide comfort during prolonged use, while hard plastic grips offer better control and driving power for quick tasks.
Fitting the Fastener
To ensure a secure fit, the screwdriver tip should closely match the width and length of the fastener’s slot. A too-large tip won’t fit into the slot, while a too-small tip can strip the screw and make it difficult to tighten or loosen.
Sliding the Tip into the Fastener Slot
Once you have the right screwdriver, insert the flat head tip into the slot on the back of the fastener. If you’re driving in a new screw or tightening a fastener, use one hand to hold the screwdriver and the other to hold the fastener steady to prevent slippage. Pre-drilling a pilot hole can make this process easier.
Tightening and Loosening Fasteners
Tightening:
To tighten an existing fastener or drive in a new one, turn the screwdriver clockwise. Hold the fastener in one hand and the screwdriver in the other, ensuring the flat head tip is firmly set in the fastener slot. Align the shaft of the screwdriver with the fastener and apply force as you turn clockwise to drive the fastener into the target material.
Loosening:
To loosen an existing fastener, turn the screwdriver counterclockwise to unthread the screw from the hole. Make sure the tip is sitting firmly in the fastener slot to prevent slippage and stripping. Apply force to the screwdriver as you turn counterclockwise. Maintain a loose grip on the fastener with your free hand to prevent it from dropping when it comes out of the hole.
Maintaining Flat Head Screwdrivers
Preventing Rust:
Flat head screwdrivers are typically made of stainless steel, but moisture and grime can lead to corrosion. After use, wipe down your tools with a clean, dry cloth to remove any moisture. Store them in a toolbox or workbench to keep them safe and dry.
Replacing Your Screwdriver
Flat head screwdrivers are durable, but regular use can take its toll. Signs of wear include a thinner tip, bending or warping, and a cracked handle. If you notice any of these signs, it’s time to replace your flat head screwdriver.
Additional Tips
- For slotted screws, ensure the screwdriver tip fits snugly into the slot to avoid damaging the screw.
- If the screw is stuck, apply penetrating oil to the threads and let it sit for a few minutes before attempting to loosen it.
- Use the correct size screwdriver for the fastener to prevent stripping or breaking the screw or the screwdriver.
- Always wear safety glasses when using a screwdriver.
