Removing Screws From Z Mount Camera: A Step-By-Step Guide

If you're trying to remove a screw from a Z-mount camera, you're probably attempting to detach a lens or adapter. If the screw is stuck, try using a screwdriver that fits the head perfectly. If you're dealing with a stripped screw, you could try using a screw extractor or drilling out the head and removing what's left with pliers. If the screw is broken, you can try using a small amount of epoxy to attach a bolt and then unscrew the broken piece.

Use a screwdriver to twist the mount anti-clockwise

To remove a stuck screw from a Z mount camera mount, you will need to twist the mount anti-clockwise. Here are some steps you can follow:

• Ensure you have the right tools: You will need a screwdriver that fits the screw head securely. A JIS screwdriver is recommended for Japanese-made cameras. If you don't have one, you can try making your own by filing a standard screwdriver to fit the screw head perfectly.
• Get a good grip: Place the camera on a stable surface or ask someone to hold it steady for you. This will help you apply more force when twisting the mount.
• Apply penetrating oil: If the screw is very tight, apply some penetrating oil, such as WD-40, to the screw head and let it sit for a while. This will help loosen the screw.
• Use a screwdriver to twist the mount anti-clockwise: Insert the screwdriver into the screw head and apply force in the anti-clockwise direction. It may require a lot of force, so be careful not to stab yourself or drop the camera. If the screw is very tight, you may need to use a pair of vice grips or pliers to get more leverage.
• Consider drilling: If the screw is still not coming out, you may need to drill a small hole in the centre of the screw and use a screw extractor to remove it. This is a delicate operation and requires a steady hand and the right tools, so proceed with caution.

Try a wrench or pliers to get extra leverage

If you're struggling to remove a screw from your Z mount camera mount, you could try using a wrench or pliers to get extra leverage. However, this method can damage your tools and is likely to shear off the bolt, so it should only be used as a last resort. Before attempting this, you could try using a penetrative agent like PB blaster or Kroil, or tapping the screw with a hammer.

If you do decide to use a wrench, you can increase your leverage by hooking another wrench into the open end of the first, or by using a cheater bar (a long metal pipe) to extend the length of the wrench. This will allow you to apply more force, but be aware that it may put a lot of stress on the wrench and it could snap. If you're worried about damaging your wrench, you could use a cheaper one or one with a lifetime warranty.

You can also use a soft-faced dead blow hammer, a rubber mallet, or a thick Allen wrench to help loosen the screw.

Drill a small hole in the screw and use a screw extractor

If you're looking to remove a screw from a Z mount camera mount, you may need to drill a small hole in the screw and use a screw extractor. Here's a step-by-step guide to help you through the process:

Step 1: Put on Safety Gear

Before you begin, it's important to prioritise your safety. Put on a pair of thick safety glasses to protect your eyes from any sharp metal shavings that may be created during the process. You may also want to wear gloves to protect your hands.

Step 2: Prepare the Screw

Using a centre punch, tap the centre of the screw head with a hammer to create a small indent. This indent will act as a guide for your drill bit, preventing it from slipping away from the centre of the screw.

Step 3: Drill a Hole

Select a drill bit that is slightly narrower than the screw head and attach it to your drill. Apply a small amount of cutting oil to the screw to lubricate the metal and make the drilling process smoother. Place the drill bit into the indent you created and drill straight down into the screw head. Drill to a depth of about 1/8 to 1/4 inch (0.32-0.64 cm).

Step 4: Use the Screw Extractor

Now it's time to use the screw extractor. Place the pointed threaded end of the extractor into the hole you drilled. Turn the extractor counterclockwise, either by hand or using a wrench, until you feel it bite into the screw. Continue turning counterclockwise until the screw is completely removed.

Step 5: Apply Penetrating Oil (if needed)

If the screw is being particularly stubborn, you can apply some penetrating oil to the screw head and threads. This will help to loosen the screw and make it easier to extract.

Remember to work slowly and carefully throughout the process, especially when drilling and using the screw extractor. Taking your time will help to prevent any damage to the screw, the camera mount, or your tools.

Try a left-hand screw or screw extractor

If you're trying to remove a screw from a Z mount camera mount, you may be able to use a left-hand screw or screw extractor. This method is particularly useful if the screw is stripped or stuck.

Left-hand drill bits are made from cobalt-fortified high-speed steel and are designed to increase durability and service life. They are used for removing broken bolts or screws and turning left to prevent further tightening of the bolt or screw.

You can use a left-hand drill bit to create a hole for the extractor to grip onto. The extractor's spiralled flutes will dig into the screw, increasing grip as torque is applied for the removal of screws, fasteners, and bolts.

If you don't have a left-hand drill bit, you can try using a centre punch or a tiny chisel and a hammer to drive the screw to loosen it. You can also try using a rubber band by placing it over the screw head and then pressing your screwdriver into it. Turn very slowly and the rubber band will fill in the gaps, providing enough friction to get the screw out.

Use a Dremel to cut a slot in the screw head

Using a Dremel tool to cut a slot in a screw head can be a quick and easy fix, but it requires a steady hand and the right equipment. Here's a step-by-step guide to help you use a Dremel to cut a slot in a stripped screw on your Z mount camera mount:

Step 1: Choose the Right Dremel Bit

Select a thin, abrasive cut-off disc or wheel for your Dremel tool. The disc should be slightly larger than the diameter of the screw. For small screws, use the thin brown discs that are not reinforced. Avoid using the thick, heavy-duty grey/black discs as they are too thick for small screws and can cause damage.

Step 2: Prepare Your Work Area

Put on safety glasses to protect your eyes from any flying debris. Ensure you are in a well-ventilated area, as the process will create sparks. Avoid having any flammable materials nearby.

Step 3: Cutting the Slot

Firmly hold the Dremel tool with both hands to maintain control. Carefully cut a slot into the stripped screw head. Do not cut too deeply, just enough so you can insert a straight-bladed screwdriver. Cut close to the middle of the screw head, but don't worry if it's a little off-centre. The goal is to remove the screw, not to make it look perfect. Try to avoid cutting into the surrounding material, such as the camera mount.

Step 4: Remove the Screw

Once you have cut a slot into the screw head, insert a large bladed screwdriver into the slot. Slowly apply power to the screwdriver to remove the screw. You can also use a power driver, but be careful as the straight bits can slip out of the slot and damage the camera mount. Once the screw is loose, you can use vice grips to take it out the rest of the way if needed.

Tips:

• Practice using the Dremel tool beforehand if you are unsure of your technique.
• You can stack two discs to create a wider slot for larger screw heads.
• Applying downward force on the screwdriver can help with removal.
• Always wear safety gear, including eye protection, when working with power tools.
• If you are unsure or uncomfortable using a Dremel tool, consider alternative methods for removing the stripped screw.

Using a Dremel tool can be an effective way to remove a stripped screw from your Z mount camera mount, but it requires caution and precision. Always take the necessary safety precautions and follow the above steps to increase your chances of success.
