Guides/General Screw Guide

Using the correct screwdriver bit when disassembling consoles is essential to prevent screw stripping, a common issue that can complicate repairs. Screw stripping occurs when the driver bit does not fit securely within the screw head, leading to slippage that wears down the metal. Although Phillips (PH) and Japanese Industrial Standard (JIS) screws appear similar, they differ in design and compatibility with specific driver bits. Using the wrong one risks stripping the screw. For example, most Nintendo handhelds made before 2015 (Game Boy, DS, 2DS, o3DS) use JIS screws, while those made after 2015 (n3DS, Switch) typically use Phillips (PH/ISO 8764) screws. This article provides guidance on using the correct screwdriver bit for various consoles, common mistakes to avoid, and effective methods for removing stripped screws.

1. Select the correct bit
   Identify and use the correct screwdriver bit that matches the screw drive (screw head) type (e.g., Philips (PH), Japanese Industrial Standard (JIS), or Torx). The bit should fit snugly into the screw head with no wobble; a loose fit increases the risk of stripping. Note:If you are using an Ifixit kit, their PH 0 to 0000 bits are actually (or way way closer to) JIS and not PH. You will need to find an other Phillips screwdriver to use. Learn more
2. Align and stabilize
   Position the screwdriver directly in line with the screw (90° angle). Holding the tool at an angle can reduce contact between the bit and screwhead, leading to slippage and wear.
3. Apply light downward pressure
   Press down very lightly on the screwdriver to maintain stable contact between the bit and screwhead. Aim to create enough downward force to prevent slipping, but avoid pressing too hard. If you find you need to press down excessively to prevent slipping, stop immediately. This often indicates that your screwdriver bit is not the correct type or size. Continuing with excessive force risks stripping the screw head with as few as one or two slips.
   Note: For small screws (smaller than PH0), apply minimal or no downward pressure, as excessive force can easily cause damage. For larger screws, apply light to firm downward pressure as needed to maintain contact, depending on the screw's tightness.
4. Turn slowly and steadily
   Rotate the screwdriver slowly in a counterclockwise motion, applying even, steady pressure. Sudden or jerky movements can increase the likelihood of slippage, especially if the screw is stubborn or tightly fastened.
5. Stop if slippage occurs
   If the bit begins to slip, stop immediately to reassess the bit size or angle. Continuing with a slipping bit can quickly strip the screwhead. Switching to a slightly larger bit may provide the necessary traction to remove the screw.

Stripped screw removal

Stripped screws can pose a challenge in electronics repair, particularly in handheld devices like gaming consoles where screws can be small and tightly secured. Stripping occurs when the screwdriver bit fails to grip the screwhead effectively, often due to using an incorrect bit or applying excessive force. This can complicate disassembly and repair efforts. Fortunately, several techniques can help remove stripped screws without causing further damage to the device. Below are effective methods to tackle stripped screws.

• Use the correct screwdriver bit: Sometimes, the correct bit can still grip the remaining edges of the screw head. If the bit slips, try one size larger than the original recommendation.
• Rubber band method: Place a flat rubber band over the screw head, then press the screwdriver into the screw through the rubber band. This adds traction and helps the bit grip the screw.
• Screw Extractor Set: A screw extractor set, like the iFixit's Precision Screw Extractor Set, can be effective for stubborn screws. Extractors are designed to bite into the stripped screw and allow for easy removal.

Advanced removal methods

If the above methods fail, there are more advanced and riskier options involving power tools. At this point, consider whether you're comfortable using tools like a rotary tool or a drill. These methods can damage the console if not used carefully, so a professional repair may be advisable if you’re uncertain.

• Drilling: Use a metal drill bit slightly smaller than the screwhead to carefully drill it out. Only drill enough to remove the head; then, use pliers to remove the remaining screw shaft.

• Rotary tool (dremel) cut: Use a rotary tool (i.e., a dremel) to create a straight groove in the screwhead. Insert a wide flathead screwdriver bit into the new groove and turn slowly to extract the screw.
