Can You Bring a Screwdriver on a Plane? TSA Rules

Yes. You can bring a screwdriver on a plane. TSA allows tools 7 inches or shorter, measured end to end when assembled, in carry-on or checked bags. Longer screwdrivers must be checked. Electric models are power tools: check the tool, keep spare lithium batteries in carry-on.

That is the current U.S. TSA rule from the What Can I Bring listings, accessed 12 September 2026. The officer at the X-ray still has the last word.

Compact precision screwdriver set in a case, the size class TSA usually allows in carry-on.

Can you bring a screwdriver on a plane? Carry-on vs checked

TSA splits screwdrivers by assembled length, not by Phillips vs flathead vs Torx. A 6-inch cabinet screwdriver and a 4-inch precision driver are treated the same way. A 10-inch mechanic's driver is not.

Item	Carry-on	Checked bag
Screwdriver 7 inches or shorter (assembled, end to end)	Yes	Yes
Screwdriver longer than 7 inches	No	Yes
Power tools, including electric / cordless screwdrivers	No	Yes (powered off; protect from accidental start)
Spare (uninstalled) lithium-ion battery	Yes (required)	No
Drills and drill bits	No	Yes
Multi-tool with a knife of any length	No	Yes (sheathe the blade)
Multi-tool with no blade	Yes	Yes

The screwdriver rows come from TSA's dedicated listings: screwdrivers shorter than 7 inches (carry-on yes, checked yes) and screwdriver longer than 7 inches (carry-on no, checked yes). The general Tools entry, last updated 21 July 2026, says the same thing in one sentence: tools 7 inches or shorter may be allowed in carry-on; power tools and all other tools greater than 7 inches must be packed in checked baggage.

TSA does not add a "must not be sharp" test to screwdrivers. The tip is supposed to be pointed. The length rule is the written test.

How TSA measures 7 inches

Measure the tool the way you would use it: handle plus shaft, end to end when assembled. That is TSA's wording on both screwdriver listings. Do not measure the shaft alone and ignore the handle. Do not unscrew a long shaft, pack the pieces separately, and treat that as a short tool. If a bit is fitted, include it. Seven inches is 17.8 cm; TSA writes the limit in inches.

A typical household #2 Phillips is often just under 7 inches. A long-reach appliance driver or a 12-inch electrician's screwdriver is over. If you are close, pack it in checked baggage.

Airport check-in queue before TSA screening, where tools over 7 inches are sent to checked bags.

What to pack where

Carry-on

A short manual screwdriver, a small precision set, and spare lithium batteries (in a case or with terminals taped) belong here. Keep the tool in a pouch so it is obvious on the X-ray and does not look like a concealed pointed object. If the checkpoint officer wants a closer look, you can pull it out without unpacking the whole bag.

Checked bag

Anything longer than 7 inches, any power tool, drills, and drill bits. TSA also asks that sharp objects in checked bags be sheathed or wrapped so they do not injure baggage handlers. A bit case or a cardboard sleeve on the tip is enough. Do not toss a loose 10-inch driver into clothing.

If you only have a carry-on and your driver is over 7 inches, you will be asked to check the bag, mail the tool, return it to a car, or surrender it. TSA does not hold tools for pickup.

Can you bring an electric screwdriver on a plane?

Treat a cordless or electric screwdriver as a power tool plus a lithium battery, not as a short hand screwdriver. TSA does not publish a separate "electric screwdriver" card. It does publish Power Tools (last updated 2 October 2024):

Power tools must be packed in checked bags, including drills and drill bits. Power tools with installed batteries must be packed in checked bags. Batteries installed in devices must be protected from accidental activation. External battery chargers that don’t require electricity and spare, uninstalled lithium batteries must be packed in a carry-on bag.

Carry-on on that listing is No. A compact precision driver with a built-in battery is still a powered tool. Some officers will wave a pen-sized driver through as a portable electronic device. That is discretion, not the written Power Tools rule.

FAA battery rules sit on top of TSA's tool rules

The Federal Aviation Administration regulates the battery, not the steel. From FAA PackSafe — Power Tools (updated 5 June 2025):

The safest packing method is to remove the battery, carry the battery on, and check the tool.
A lithium-ion battery in a power tool may travel in checked baggage only if the tool is completely powered off, protected from accidental activation (a manufacturer's case is the example FAA gives), and within the watt-hour limits below.
Spare lithium batteries must be in carry-on baggage. They cannot be checked. If your carry-on is gate-checked, take the spares out and keep them with you in the cabin.

Watt-hour limits, from TSA's lithium batteries ≤100 Wh listing and FAA PackSafe — Lithium Batteries (updated 11 August 2026):

0–100 Wh lithium-ion: allowed for passenger use. This band covers nearly all everyday device batteries.
101–160 Wh: up to two spare batteries per person, airline approval required.
Over 160 Wh: not allowed on passenger aircraft.
Lithium metal (non-rechargeable): 2 grams of lithium per battery; 2–8 grams needs airline approval, two-spare cap.

To read Wh if the pack is not marked: volts × amp-hours. If the label is in mAh, divide by 1,000 first, then multiply by volts. A compact electric screwdriver pack is almost always in the 0–100 Wh band. Confirm the number on the battery, not a blog estimate.

Protect spare terminals from short circuit: original packaging, tape over the contacts, or a separate pouch. Damaged, defective, or recalled lithium batteries are not allowed in carry-on or checked bags.

Bits, multi-tools, and drills are not the same listing

A small case of screwdriver bits is not, by itself, a 7-inch tool. TSA's separate Drills and Drill Bits listing is carry-on no, checked yes. If you pack masonry or twist drill bits with a precision set, expect the officer to treat the drill bits as that listing and send them to checked baggage. Long screwdriver bits that make an assembled driver longer than 7 inches belong in checked bags with the tool.

Multi-tools with a knife of any length are prohibited in carry-on, even if the screwdriver bit is short. Pack those in checked bags with the blade sheathed. A bladeless multi-tool is allowed in carry-on or checked bags.

A cordless drill is not a screwdriver. It is a power tool and, on its own TSA card, carry-on no. Do not try to "count it as under 7 inches."

What this page does not cover

This is U.S. TSA screening for flights departing U.S. airports. Other countries often use a shorter shaft limit, or they ban tools from cabin bags. Check that country's screening agency before you pack.

It is also not a reason to bring a full kit into the cabin. A short driver for glasses, a laptop hinge, or a hotel furniture screw is the use case. A loaded tool bag, a hammer, a saw, or a crowbar is checked baggage, and some of those are checked-only regardless of length.

For how to use the tool once you land, see screwdriver handling and bit-safety basics — that is a workshop page, not a packing page.

The officer still decides

Every TSA What Can I Bring card ends with the same line: the final decision rests with the TSA officer on whether an item is allowed through the checkpoint. Even a 5-inch driver can be pulled for extra screening. If the tool is not listed, or you are flying with an unusual battery pack, AskTSA answers daily (live help 8 a.m.–6 p.m. ET) via X, Facebook Messenger, Apple Business Chat, or text "Travel" to 275-872. Confirm before you leave for the airport, not at the belt.
