Hey everyone, if you’ve ever spent time at a metal fabrication, woodworking, or electronics repair shop, you know the pain of trailing extension cords, power adapters, and tangled cables around a steel workbench. You’re reaching for a drill, your phone dies mid-job, and you’re tripping over cords that aren’t even supposed to be on the floor. That’s why installing a power strip right on your steel workbench is such a game-changer—easy access, no mess, and way less risk of knocking over tools or tripping. Steel Workbench
Full disclosure: I’m part of a team that builds commercial-grade steel workbenches, so I’ve seen every messy, janky way people try to attach power strips over the years. Some drill random holes and end up weakening the bench’s frame. Others tape them on and they fall off when a power tool vibrates the bench. Today, I’m walking you through the right, safe way to do it—no mistakes, no damage to your bench, and it’ll last as long as your workbench itself.
First, let’s talk about why this is different from mounting a power strip on a wooden bench. Steel workbenches are built thick—our standard ones have 14-gauge steel frames, so they’re sturdy, but they’re also hard to drill, and you don’t want to mess up the structural integrity. Plus, steel conducts electricity, so skimping on wiring or using the wrong hardware can be a fire hazard. We’ve had customers come to us after ruining their new steel bench because they used cheap fasteners or skipped sealing the holes. I’m not here to sell you a bench yet, but trust me—your bench is an investment, so you want to treat it right.
What You’ll Need Before You Start
Let’s get the supplies out of the way first, so you don’t run to the hardware store mid-project and make a bad choice.
- The right power strip: This is non-negotiable. Don’t grab the cheap $5 one from the gas station. You need a heavy-duty, grounded power strip rated for at least 15 amps (1875 watts) if you’re running power tools, or 10 amps (1250 watts) for smaller stuff like phone chargers or soldering irons. Look for one with metal housing, not plastic—plastic will melt if you have a power tool leak power (it happens) and won’t hold up to vibration. Also, get one with a long, heavy-duty cord (10ft minimum) so you don’t have to stretch it across the shop. Avoid daisy-chaining power strips—just get one big enough for all your tools.
- Mounting hardware for steel: Regular wood screws won’t work here. You need ¼” self-tapping sheet metal screws, ½” long. These drill into steel without pre-drilling a hole, and they’re strong enough to hold the power strip plus all the weight of plugs. Get 4-6 screws—more if the power strip is extra long.
- Thread sealer: This is a small tube, I promise. It’s for sealing the screw holes after you mount the strip, so dust, metal shavings, or liquid (like a spilled soda) don’t get into the holes and cause rust on your steel bench. Our benches have a powder coat finish to prevent rust, so this step protects that, too.
- A drill with a metal bit: A regular wood drill bit will bounce off steel and ruin it. A ¼” twist bit for metal works, or even a drill driver—just make sure it’s sharp. Pro tip: If you drill slow, you’ll get cleaner holes without leaving big burrs on the steel.
- A stud finder (optional, but helpful): Your steel workbench has a frame (that’s the stiff, horizontal bar under the top surface) and a work surface. You want to mount the power strip to the frame, not the thin top skin, because that’s where the bench is strongest. A stud finder (or even a strong magnet) will help you find the frame so you don’t drill into empty space.
Step 1: Pick the Perfect Spot on Your Steel Workbench
This is where most people mess up. Don’t just slap the power strip anywhere. You want it where you can reach it easily, but not where it’s in the way of tools. Here’s our go-to rule: Mount it on the underside of the workbench, 6-8 inches from the front edge, right above your dominant hand. If you’re right-handed, it’s on the left side of the bench; left-handed, right side. That way, you don’t have to reach all the way across the bench, and tools like a drill or sander don’t knock into it.
Wait—why underside? If you mount it on top, it’s a tripping hazard, and any metal shavings from your projects will fall into the power strip’s slots, causing electrical issues. Underside is also protected from spills (like if you’re using solvents nearby) and it’s out of the way when you’re cutting wood or metal.
Also, make sure there’s space behind the spot for the cord to run. You don’t want to drill the strip on and then realize the cord has to squeeze between the bench and a wall or another tool. Measure the cord length against the distance from your power outlet on the shop wall to the spot you picked. If the cord is 10ft, make sure the outlet is within 10ft of that spot—no extension cords needed there either.
Step 2: Mark the Holes (No Random Drilling!)
Take the power strip, hold it up to the underside of your bench where you marked the spot. Mark the four mounting holes on the strip with a pencil. If your strip has extra holes (for longer strips, sometimes they have 6), mark those too.
Now, if you found the frame with the stud finder, make sure the pencil marks line up with the frame, not just the thin top of the bench. The frame is where the strength is—if you drill into the thin top, the screws will pull out over time, especially when your bench vibrates from tools running. For our steel workbenches, the frame runs about 2 inches below the top surface, so the underside is where the frame is easy to hit.
Pro move: If you’re worried about scratching the powder coat on your bench (we know how much you care about that finish), put a piece of masking tape over each pencil mark. The tape will keep the drill from slipping when you start—no scratchy accidents.
Step 3: Drill the Holes the Right Way
Grab your drill with the ¼” metal bit, set it to a low speed (around 1500 RPM—higher speed will heat up the steel and make the bit dull faster). Now, drill straight down through each of your marked holes. Go slow, don’t push hard—let the bit do the work. If you push too hard, you’ll bend the steel or break the bit.
Once you drill all four holes, you’ll have little burrs around the edges of the holes. You can leave them, but if you want, use a metal file to smooth them down so the screw doesn’t catch on anything when you mount the strip. No need for fancy tools—even a small sanding block works.
Step 4: Mount the Power Strip Securely
Take your power strip and line up its mounting holes with the ones you just drilled. Now, take your ¼” self-tapping sheet metal screws. Drive them in with your drill, again on low speed. Go slow until the screw is tight—don’t over-tighten it! If you crank it too hard, you’ll strip the screw threads, bend the steel, or even crack the power strip’s housing (even metal ones are a little delicate). You should feel firm resistance, and the power strip shouldn’t wiggle at all when you tug it.
Wait a second—double check: Did you mount it to the frame, not the top skin? Give it a good shake. If it moves even a little, take the screws out and move the holes to the frame. That tiny mistake will save you from the power strip falling off mid-project later.
Step 5: Seal the Holes to Protect Your Steel Bench
This is the step most people skip, and it’s why so many steel benches get rust spots. The screw holes you drilled are tiny, but if you don’t seal them, moisture from the air, dust, or a spilled drink will get in and start to rust the steel from the inside. That’s bad news—rust weakens the bench over time.
Grab your thread sealer, put a tiny bead on the threads of each screw, then screw the screws back in. Once they’re tight, put a little more sealer around the edge of each hole on the underside of the bench. Wipe off any excess with a rag, so it doesn’t look messy. This stuff is cheap, takes 30 seconds, and will keep your bench looking good for years. Trust me, we’ve seen customers who skipped this step end up with rust spots on their bench 6 months later—don’t be that guy.
Step 6: Test It (Safety First!)
Now, plug the power strip into your shop’s outlet, and plug in a small, low-power device first—like a lamp or your phone charger. Make sure it turns on, and the power strip doesn’t get hot. If it’s hot, that means you used a strip that’s too small for your needs, so unplug it and get a heavier-duty one.
Next, give the power strip a good tug, and shake the bench a little. It shouldn’t move at all. If it does, go back and tighten the screws a little more—but not too much. If all checks out, plug in your most used tools, and you’re good to go.
Bonus Tips From Our Team (We Build These Benches Every Day)
- If your power strip is longer than 2ft, add an extra mounting hole in the middle. The middle of long strips can bend under the weight of plugs, so a fifth or sixth screw will keep it straight.
- Don’t mount the strip too close to the back edge of the bench. The cord needs space to run to the outlet, and you don’t want to accidentally yank the strip when you’re reaching for a tool in the back.
- If you’re working with really heavy tools (like a 7-inch grinder or a big table saw), get a surge-protected power strip. It’ll protect your tools from voltage spikes, which can ruin expensive motors.
- If you rent or have a bench that’s not ours (no hard feelings), this still works! Just make sure the frame is solid, not a thin metal sheet that’s flimsy. If your bench is wobbly to begin with, you might want to reinforce the mounting spot with a small metal bracket first—ask any hardware store for a small L-bracket that fits.
