How to Install Bolt on Climbing Holds

If you’ve ever wondered how to install bolt on climbing holds, you’re not alone. Climbers all over the world have been wondering the same thing. Many hold types require different bolt installation methods vary from one another. This article will cover all of them. Machined natural stone, Hollow-backing, and Screw-on holds are some of the more common ones. To install a bolt on climbing holds, you should follow these guidelines.

Screw-on holds

When installing bolt-on climbing holds, you need to be aware of the steps required for proper installation. Generally, hold manufacturers include the hardware with the hold. However, you will still need to drill holes into the wall and attach the hold to it with screws. The screw size will depend on the thickness of the plywood and the climbing hold. If you are going to screw the hold against a concrete wall, you should drill two holes first.

Use the correct size of the screw or t-nut to install the hold properly. Make sure the screw is small enough to pass through the hold, otherwise it won’t fit in the t-nut. Also, don’t over-tighten the screws. You might damage the hold or panel if you over-tighten the screws. Make sure you use a level to ensure the hold is level.

If you’re not sure about the location of the hold, you can use a screwdriver to drill holes. Make sure the screw is recessed and is not exposed. Then, use a hacksaw to cut the bolt. After removing the screw, reinstall the hold by removing the T-nut. This technique is great if the wall isn’t already securely screwed and there’s no room to install a rock hold.

If you’re looking for a fast and reliable way to mount your climbing holds, consider using bolt-on climbing holds. These types of holds are easier to install and require less tools than their counterparts. When you’re installing bolt-on climbing holds, make sure you have the correct tools and are sure to follow the instructions carefully. If you follow the instructions, you’ll be able to install bolt-on climbing holds safely in no time.

Machined natural stone

There are several advantages of using machined natural stone for bolt on climbing holds. First, these hold types are much more durable than traditional resin ones. They are also more environmentally friendly, although they do require extra care during installation. Machined natural stone is not as easily chipped as resin, and the bolts will stay secure even if the wall is uneven. In addition, this type of hold is much lighter than the resin versions.

Often, big-wall climbers place bolts manually. They are often hanging on funky heads or skyhooks, and don’t have time to drill a 12 mm five-piece bolt. Instead, they use super-strong hardware, which is lighter and easier to install, but only works well on routes with light traffic. This hardware is suitable for granite, quartzite, and limestone. But it’s also very difficult to remove if the rock gets wet.

Machined polyurethane

Machined polyurethane is used for climbing holds for several reasons. First, it is lightweight and durable. The material is also less likely to break than polyester, making it the ideal choice for holds for sport climbing. Also, unlike polyester, polyurethane holds are easier to rotate, which allows for higher leverage to move them. However, they do suffer from a few drawbacks. Read on to learn more about this material and its pros and cons.

Second, the manufacturing process is important. Many hold companies don’t disclose their manufacturing methods. They may choose to embrace a romantic image of a passionate climber creating a hold in his garage. In reality, however, manufacturing holds in a professional facility is necessary to meet the demands of climbing enthusiasts and climbers while also providing a safe working environment. These two issues are not exclusive to the climbing hold industry, however.

A high-quality climbing hold should also be resistant to breaking. Using a high-grade polyurethane is recommended for holds that are exposed to severe impacts. Machined polyurethane is also more durable than standard elastomeric rock. Machined polyurethane is also good for holds used in sport climbing. A good machined polyurethane hold will keep the climber stable and protected for longer.

Alternatively, handholds may be mounted on a noodle structure. In such cases, a bolt-on climbing hold is typically comprised of a polymeric foam cylindrical member that extends substantially outward from the hand hold. Additionally, the climbing hold may have a removable structure such as a cylindrical magnetic member with a flag attached to it. A climbing hold may also include an elongated member with an aperture in its surface.


Before installing a climbing hold with a hollow-backing bolt, you must first drill holes for it. You can use a hammer drill or 3/16″ drill bit. Make sure to clean out the drill hole thoroughly after drilling. Then, drill four holes in the wall, each with a quarter-inch pilot hole. Place the bolts through the holes, and use your judgment to space them evenly. Install one bolt per hold.

You should also camouflage the hangers. For a camouflaged look, you can spray-paint the hangers with flat primer before installing the bolts. However, do not paint the hangers in the rock! It will chip off. Use stainless-steel bolts and hangers unless they are titanium glue-ins. The spacing between the two pieces of hardware is also important.

Stainless-steel bolts are the most popular choice for outdoor applications. However, if you’re installing the bolts in a crag with harsh weather conditions, you might want to use a different material. While plated steel bolts are cheap initially, they may need replacing more often. If you’re a beginner, you may not be motivated to upgrade your hardware as soon as possible.

First, you’ll want to select the best location for the clipping points. Choose a place near solid holds and comfortable climbing positions. The location of the future bolt should be a basketball-size area, free of hollow and fragile rock. Avoid placing the bolts next to edges or corners. If you’re unsure, take a few practice climbs before you do it! You’ll be glad you did.


The first thing you need to know when installing T-nuts on your climbing holds is that you have to make sure that they are installed squarely with the plywood panel. If not, you’ll run the risk of them spinning and will need to pull them out. You can easily fix this problem by drilling a hole and inserting a wood screw into the nut’s threads. If you’ve made a mistake during installation, you can also use a drill and a 3/8″ threaded rod to set the T-nuts in place.

The hammer method is one way to install t-nuts on climbing holds. While this is the most common way to install bolts, it can cause crooked T-nuts or worse, strip the backside of the plywood. If this happens, it can be difficult to retrieve the hold later. You should use higher-end t-nuts. If you don’t have these tools, you can use a cordless drill to attach them.

Before you install T-nuts on climbing holds, you need to choose the right size for the screw running through the holds. T-nuts with larger diameters will have a greater safety margin than small ones, but a random pattern can create gaps. If your wall is less than eight feet in height, you should install more T-nuts near the top and bottom of the wall and fewer near the middle. This may result in some T-nuts over the studs.

For home woodies, a 5″x5″ pattern works well. Alternatively, you can drill holes from the climbing side of the plywood. Remember to drill from the side of the wall, as this will prevent splinters on the climbing side. This way, you’ll have more variety in the way you climb. In any case, make sure to use a saw horse. It will make drilling the holes easier.
