If you need to adjust or repair your NordicTrack treadmill, you’ll likely need a hex key. Finding the right what size hex key for nordictrack treadmill is the first step to getting your machine back in working order. This guide will help you identify the correct size and provide tips for using it safely.
What Size Hex Key For Nordictrack Treadmill
Most NordicTrack treadmills use a standard metric hex key size. The most common size you’ll need is a 5mm Allen wrench. This size is used for many assembly and adjustment points, including the console mast, handrails, and some roller adjustments.
However, it’s not the only size used. Having a set of hex keys is a good idea. You might occasionally need a 4mm or 6mm key for certain components. Always check your owner’s manual first, as it will list the exact tools required for assembly and maintenance.
Why the Correct Size Matters
Using the wrong size hex key can cause damage. A key that’s too small can strip the head of the bolt. This makes it almost impossible to remove later. A key that’s too big won’t fit properly and will also damage the bolt.
Stripped bolts are a major headache. They often require special extraction tools to fix. Taking a moment to find the right size saves you time and frustration in the long run. It also ensures your adjustments are secure and safe.
How to Identify the Size You Need
If you don’t have your manual, don’t worry. You can figure out the size a few different ways. First, look at the bolt itself. Sometimes the size is stamped on the head. If not, you can measure it.
- Check a Set: Try different sizes from a hex key set. The correct one will fit snugly without any wiggle room.
- Measure the Distance: Use a ruler or calipers to measure the distance between two parallel flats on the bolt head. This measurement in millimeters is your hex key size.
- Look at Common Areas: The bolts for the console and handrails are usually 5mm. Smaller hardware, like certain covers or motor shrouds, might use 4mm.
Recommended Tool Sets
Instead of buying a single hex key, invest in a good set. This gives you flexibility for any project. Look for these features:
- A fold-up set of L-keys in metric sizes (usually 1.5mm to 10mm).
- A set of hex bits for a socket wrench or drill driver. These are great for faster assembly/disassembly.
- A T-handle hex key. These provide more torque and are easier to grip.
Step-by-Step Guide to Using Your Hex Key
Once you have the right tool, using it correctly is key. Follow these steps for safe and effective adjustments.
- Unplug the Treadmill: Always disconnect power from the outlet before working on your treadmill. This prevents accidental starts and protects you from electrical shock.
- Locate the Bolt: Identify the bolt you need to tighten, loosen, or remove. Clear any dust or debris from the area.
- Insert the Key Fully: Push the hex key all the way into the bolt head. Ensure it’s seated completely to avoid slipping.
- Apply Steady Pressure: Turn the key slowly. Use firm, steady pressure. If it’s very tight, don’t force it; you might need a longer tool for more leverage.
- Tighten Securely: When reassembling, tighten bolts firmly but do not overtighten. Over-tightening can strip threads or crack plastic parts.
Common Treadmill Adjustments Using a Hex Key
Here are a few tasks where you’ll likely need your hex key:
- Leveling the Deck: The rear rollers can often be adjusted with a hex key to level the walking belt.
- Tightening the Handrails: Over time, the handrails may loosen and need tightening.
- Securing the Console Mast: The mast that holds the screen can sometimes wobble if its bolts loosen.
- Belt Tension and Centering: While belt adjustments often use a special tool, some models use hex keys for the rear roller adjustment bolts.
What to Do If You Strip a Bolt
Accidents happen. If you do strip a bolt head, here are a few things you can try. First, you can try using a rubber band. Place a wide rubber band over the stripped head, then insert the hex key and turn slowly. The rubber can fill the gaps and provide grip.
If that fails, you might need a screw extractor kit. These kits have special bits that bite into the damaged metal to remove the bolt. As a last resort, you may need to drill out the bolt. This is tricky and it’s often best to contact NordicTrack support or a local repair technician if you’re not comfortable.
Maintenance Tips to Keep Your Treadmill Running Smoothly
Regular maintenance reduces how often you need your hex key. A well-kept machine has fewer loose parts. Follow these simple tips:
- Clean Regularly: Wipe down the deck and console to prevent dust buildup, which can interfere with mechanics.
- Lubricate the Belt: Follow your manual’s instructions for lubricating the walking belt every few months. This reduces friction and wear.
- Check for Loose Parts: Every month, gently check handrails and the console for any movement. Tighten as needed with your hex key.
- Keep it Clear: Make sure the area around and under your treadmill is free of dust bunnies and obstructions.
FAQ: Your Hex Key Questions Answered
What size Allen wrench for NordicTrack treadmill assembly?
The primary size for assembly is 5mm. Your treadmill’s box should include the necessary tools, but having your own set is more reliable.
Do all NordicTrack models use the same size?
Most do, but there can be exceptions. Newer or commercial models might use different fasteners. The 5mm is standard, but always verify in your model-specific manual if possible.
Can I use a drill with a hex bit?
You can, but be extemely careful. Use a low torque setting and only for assembly or removing many bolts. For fine adjustments like belt tension, always use a manual tool to avoid damaging sensitive components.
Where can I buy a replacement hex key?
You can find hex keys at any hardware store, home center, or online retailer. A basic metric set costs very little and is a valuable addition to your toolbox.
My treadmill didn’t come with a tool. What should I do?
First, check the box and the plastic bags of hardware thoroughly—sometimes it’s tucked away. If it’s truly missing, a standard 5mm hex key from a store will work. You can also contact NordicTrack customer service for a replacement.
Having the correct tool makes treadmill maintenance simple. With your 5mm hex key (and maybe a few others in a set), you’ll be prepared to handle common adjustments and keep your NordicTrack running smoothly for years to come. Remember to always prioritize safety by unplugging the machine before you start any work.
