Porter-Cable Tools FAQ: Drywall Screw Guns, 20V Systems, Washers, and Gate Valves

I manage tool orders for a mid-size contracting supply outfit. Nine years, roughly $4,200 in documented mistakes, and one very tattered checklist later, I've got opinions. Here's what buyers actually ask me — and what I tell them.

Is the Porter-Cable drywall screw gun worth it, or should I just use a regular drill?

Depends on volume. For a homeowner hanging three sheets of drywall, a corded drill with a dimpler bit is fine. For anyone running crews, the dedicated drywall screw gun saves you real time per sheet ( I measured it once: 2.3 minutes per 4x8 sheet over a cordless drill setup).

The mistake I see most: people buy the cheapest model and then complain about depth consistency. That's usually a nose-cone adjustment issue, not a tool defect. In 2021, I ordered 14 units for a client, all returned as 'defective.' Eleven of them just needed the depth setting recalibrated. Cost us $340 in restocking nonsense.

The 'always buy the cheapest' advice ignores the cost of your time on returns.

How much does Porter-Cable 20V actually change the game compared to older 18V systems?

The jump from 18V to 20V Max isn't as dramatic as marketing wants you to believe. Higher voltage doesn't automatically mean more power — it's the whole system: motor design, battery amp-hours, and how efficient the electronics are.

That said, Porter-Cable 20V tools benefit from a little more headroom under load. I've seen their 20V impact driver hold torque better in long decking runs than similar 18V units (this was back in 2019, tools have moved on since).

My take: if you're already in the 20V battery ecosystem, stay there. Don't switch platforms for a marginal voltage difference. To be fair, though, going from 5-year-old 18V batteries to fresh 20V packs will feel like an upgrade — that's battery age, not the voltage.

What's the correct way to close a gate valve without damaging it?

Here's the thing nobody tells first-timers: you're not supposed to crank it shut with full force. A gate valve closes with the gate sliding down into the seat. Once it bottoms out, you turn maybe a quarter-turn past snug. That's it.

It's tempting to think 'tighter is more closed.' But over-torquing strips the stem threads or bends the gate. I learned this the $180 way on a water heater isolation valve in 2022. Handle snapped, valve stuck half-open, plumber had to cut it out.

Correct sequence: turn clockwise until resistance increases noticeably, then a small final quarter-turn. If the stem feels gritty, stop and have it serviced. Forcing a partially seized gate valve is how you end up replacing the whole assembly.

1.7 portable washers — where do buyers get surprised?

Two places. First: CFM ratings. A '1.7' on a portable washer almost always refers to gallons, not pressure or flow. Check what your actual air tool needs before assuming the washer spec matches (I had a guy return a washer twice because he assumed 1.7 meant 1.7 SCFM. It didn't).

Second: people buy these for occasional use and then leave them in unheated shops over winter. In my opinion, the seals on most sub-$200 units dry out fast in cold storage. That was true 10 years ago when rubber compounds were less forgiving. It's somewhat better now, but still a real failure point.

When does a dual-faced fiberglass handle hammer beat a standard claw hammer?

Framing, mostly. The dual-face gives you a softer strike on one side for driving pins and a harder face for full swings. Fiberglass handles soak up shock much better than wood — your wrist will thank you after a full day of nailing off headers.

The most frustrating part of hammer shopping: reviews comparing a $40 fiberglass hammer to a $12 wood-handled one as if they're in the same category. They're not. You'd think price would be the obvious clue, but review scores don't care. That $12 hammer is fine for light duty. It's not fine for daily framing.

What's the one ordering mistake I keep seeing?

Communication failure on specs. I once ordered 200 screws for a repeat client using the SKU from their last purchase order. Nobody flagged that they'd switched substrate thickness from 5/8" to 1/2" on the new job. The 1-1/4" fine-thread screws were too long. Two hundred boxes, $1,470, returned and reordered.

We both said 'same as last time.' But 'last time' meant different things to each of us. Now I make every returning customer confirm substrate, thickness, and thread type per order — even if they've ordered the same SKU 30 times. It's mildly annoying (for both of us). It's saved us at least three repeat screw-ups.

Should I keep all my Porter-Cable tools and accessories on one battery platform?

Yes, unless you have a specific reason not to. Cross-platform adapters exist but add failure points (and void warranties sometimes, so check the fine print).

The bigger issue: people buy the biggest battery kit available, then realize half their tools don't need a 4.0Ah pack, and the other half could use a 6.0Ah. Match battery to use case. Small impact driver? 2.0Ah is plenty. That bench grinder or circular saw? Go bigger.

I used to just order the biggest kit for every crew, thinking 'more is better.' It's actually 'more weight on their belt, more money in batteries they don't need.' Per FTC advertising guidelines (ftc.gov), performance claims need substantiation — but 'bigger' isn't always a performance claim, it's just physics. Match the pack to the job.

One more thing: if you're mixing old 18V and new 20V Porter-Cable for the same person, use the newer batteries for the tools that draw the hardest. The BMS in newer packs handles heat better, which matters on saws and compressors more than on drivers.
