Gretch Guitar Strap Lock Screw Came Loose: Quick Fix Guide

Gretch guitar strap lock screws coming out is a common issue. This is due to the design of the screw, which loosens the left-hand threaded end that is in the body as you screw down the button onto the strap end. To fix this issue, Gretch guitar owners have tried various methods, such as using super glue, epoxy, or toothpicks to tighten the screw hole. Others have replaced the Gretch strap locks with those from different brands, such as Schaller or Dunlop.

Using Schaller strap locks as replacements

Schaller strap locks are a great replacement option for your Gretch guitar's strap lock screw. They are known for their unique design, functionality, and security. Here's a step-by-step guide on how to use Schaller strap locks as replacements:

Choose the Right Schaller Strap Locks:

Select the Schaller S-Locks that match the size of your guitar's existing strap buttons. The S-Locks come in three sizes: S, M, and L. The M size is the most commonly used. Each size corresponds to a specific wood thread size and strap button length. Make sure to measure the hole in your guitar's strap to choose the right size.

Prepare the Guitar:

Before installing the Schaller strap locks, carefully unscrew the existing strap buttons from your Gretch guitar. Place a piece of cardboard between the metal tools and your guitar to protect its finish. You may also need a precision screwdriver, such as a PHO (Phillips Head #0), to assist in the removal process.

Install the Schaller Strap Locks:

The Schaller strap locks typically come with an installation guide. Follow the instructions provided by the manufacturer. Generally, you will need an Allen key (size 3 mm/ 1/8") to install the strap lock buttons. Apply wax to the thread of the screw before installing to prevent damage.

Adjust the Strap:

Once the Schaller strap locks are installed, it's time to adjust your guitar strap. Make sure the locking end of the strap locks is oriented correctly, with the "U" shape opening facing up when wearing the strap. You may need to trim the leather around the strap hole for a better fit. Use a socket wrench to secure the locking end to the strap.

Final Checks:

After installing the Schaller strap locks, give your guitar a gentle shake to ensure the strap locks are secure and silent. Check that the locking mechanism is engaged and that your guitar strap is securely attached. Test the strap by picking up your Gretch guitar and ensuring it remains safely in place.

By following these steps and using Schaller strap locks as replacements, you can enhance the security and functionality of your Gretch guitar's strap system, ensuring your instrument remains safely attached to the strap during performances and practice sessions.

Using a toothpick and wood glue to fix the screw hole

If the screw hole for your Gretch guitar strap lock is stripped, you can fix it using a toothpick and wood glue. This method is tried and tested by many guitar owners and is a quick and easy fix.

To start, take an ordinary wooden toothpick and stick it into the stripped screw hole. You can use a pen or marker to mark slightly below the surface level, so you know how much of the toothpick to cut off. You want to ensure the toothpick is deep enough in the hole so that the tip of the screw can push down on it. Cut the toothpick to size, using scissors or nippers, and generously coat the bottom of the toothpick with wood glue.

Next, stick the toothpick into the screw hole and use a hammer to gently tap it, ensuring it is as far into the hole as possible. Let the glue dry for 1-2 hours. Once the glue is dry, use nippers or scissors to cut off the end of the toothpick, so it is flush with the surface of the guitar body. Finally, screw in your strap lock as normal. The screw will push the toothpick down and to the side, giving it something to bite into.

Some people prefer to use super glue for this fix, but wood glue is recommended as it is designed specifically for wood bonding. You can also use golf tees, matchsticks, or small wooden dowels instead of toothpicks. If you use a wooden dowel, drill out the hole with a bit larger than the stripped area, add wood glue, tap in the dowel, and then cut it flush.

Using super glue and baking soda to fix the screw hole

If the screw hole in your Gretch guitar is stripped, you can use super glue and baking soda to fix it. Here's a step-by-step guide:

• Find a toothpick, some super glue gel, and baking soda.
• Squeeze a small amount of super glue gel onto the end of the toothpick.
• Use the toothpick to apply the glue into the screw hole, ensuring it gets into the crevices.
• Dip the glue-covered end of the toothpick into the baking soda so that it is coated with the powder.
• Quickly insert the coated end of the toothpick into the screw hole and hold it there. The super glue and baking soda mixture will set up rapidly.
• Once the glue has cured, use wire cutters or bull nose pliers to snip off the excess toothpick, leaving it flush with the screw hole.
• Create a pilot hole through the remaining toothpick with an awl or small drill bit.
• Finally, screw in your strap lock or screw as usual.

This method works because baking soda acts as an accelerant, causing the super glue to set very quickly. It also helps fill in gaps and creates a stronger bond, making it ideal for repairing stripped screw holes.

Using quick wood to fix the screw hole

If the screw hole in your Gretsch guitar has become stripped, you can use a product called Quik Wood to fix it. Quik Wood is an epoxy resin that you mix with your fingers and then stuff into the hole. After 45 minutes, it hardens, and you can screw into it with no problem.

• Purchase Quik Wood from a hardware store or online.
• Mix the epoxy resin components according to the package instructions.
• Use your fingers to mix the epoxy thoroughly until it forms a uniform colour.
• Stuff the mixed epoxy into the stripped screw hole. Make sure to push it in tightly and level it off flush with the surface.
• Let the Quik Wood harden for at least 45 minutes.
• Once hardened, you can screw into the Quik Wood as you would with regular wood.

If you are unable to find Quik Wood, there are alternative methods to fix a stripped screw hole:

• Use wood glue and toothpicks: Dip toothpicks in wood glue and insert them into the hole. Let the glue dry, then snap off the ends of the toothpicks and drill a new pilot hole for your screw.
• Use a screw hole repair kit: These kits usually contain metal meshes or wooden pieces that you glue into the hole to provide a new surface for the screw threads to grip.
• Fill the hole with auto body filler: Enlarge the hole with a drill, fill it with auto body filler, and then drill a new hole for your screw.

Using blue Loctite thread locker to prevent screws from coming loose

If you're having trouble with your Gretch guitar strap lock screw coming loose, you might want to try using blue Loctite thread locker to prevent it from happening again. Blue Loctite is designed to lock and seal threaded fasteners and prevent loosening caused by vibration. It also protects threads from rust, leaks, and corrosion.

To use blue Loctite thread locker, first make sure the nut and bolt are clean and free from oil or dirt. Apply a few drops of the product to the bolt, specifically where the nut will engage with it. As you twist the nut onto the bolt, the Loctite will spread around and form a seal. Twist the nut to the desired point and allow 24 hours for the product to fully cure.

Blue Loctite is a medium-strength formula that can be used on 6-19mm fasteners. It's ideal for small motors, mowers, and power equipment, as well as car parts, bicycles, and furniture. The benefit of using blue Loctite is that it can be easily removed with hand tools if you need to service or adjust the parts in the future.

One user on a Gretch guitar forum suggested using blue Loctite thread locker to prevent their strap lock screw from coming loose. They mentioned that it would still allow the screw to be backed out if needed but would keep it snug and prevent it from working itself out.
