Can You Bring a Screwdriver on a Plane? TSA Rules (2026)

Reader-supported. We may earn a commission on purchases through our links. Disclosure ›

Yes, you can bring a screwdriver on a plane, but the size determines where it goes. Screwdrivers 7 inches and under (measuring the entire tool, handle included) are allowed in carry-on. Screwdrivers over 7 inches must go in checked baggage. This applies to all tool types, including flathead, Phillips, Torx, and multi-bit sets.

There’s no restriction on screwdrivers in checked baggage regardless of size.

TSA’s 7-Inch Rule for Tools

TSA’s official rule: tools 7 inches or less (measured with the handle) are allowed in carry-on. Tools over 7 inches must be in checked baggage. This covers screwdrivers, wrenches, pliers, and similar hand tools.

What “7 inches” means in practice:

• A standard pocket screwdriver (4 to 5 inches): carry-on fine
• A small multi-bit kit (under 7 inches folded): carry-on fine
• A full-size flathead or Phillips driver (8 to 12 inches): must go checked
• A precision screwdriver set with individual drivers under 7 inches: carry-on fine

If you’re not sure about a specific driver, measure it from tip to end of handle before you pack.

Carry-on vs Checked: Which Is Better?

If your screwdriver is small enough to go either way, carry-on is usually the smarter choice for a few reasons:

• Access at destination. If you need it for a project immediately on arrival, carry-on means you have it without waiting for bags.
• Less risk of loss. Checked bags occasionally get lost or delayed. A tool in checked means you might arrive without it.
• Security screening. Small tools in carry-on tend to pass X-ray quickly. Packing them in a clear bag or separate case makes the agent’s job easier.

For heavy tools or full tool sets, checked is the only option anyway (most sets include drivers longer than 7 inches).

Packing Tips for Screwdrivers in Carry-on

• Put tools in a clear pouch. If the agent wants to inspect them, a clear bag makes it faster. You can hand the whole pouch over without digging through your bag.
• Cap or sleeve the tip. Loose screwdrivers with exposed tips occasionally get flagged for their pointy end. A rubber tip cap or the original plastic sleeve prevents this.
• Keep it accessible. You don’t need to remove screwdrivers from your bag at security (they’re not like electronics). Just make sure they’re not hidden under a laptop or other electronics that need to come out.

Other Tools on Planes: Quick Reference

• Wrench/pliers: Same rule as screwdrivers. 7 inches or under in carry-on, over 7 inches in checked.
• Drills (battery-powered): Must go in checked. Both the drill body and the spare lithium battery fall under specific airline rules for lithium batteries.
• Box cutters/utility knives: Must go in checked. No exceptions for size.
• Multi-tools with a knife blade: Must go in checked because of the blade.
• Multi-tools without a knife: Allowed in carry-on if under 7 inches.
• Hammers: Must go in checked. TSA explicitly restricts hammers from carry-on regardless of size.
• Cordless drill batteries (lithium): Must travel in carry-on, not checked (same as other lithium batteries).

International Flights

US-originating rules apply at the departure airport. When flying internationally, some countries have stricter rules about tools in carry-on. UK and EU airports generally follow a similar policy to TSA, but individual agents can exercise discretion. If you’re flying through a strict security system (like some Middle Eastern or Asian airports), pack tools in checked to avoid questions.

Frequently Asked Questions

Can I bring a screwdriver in my carry-on bag?

Yes, as long as the total length (including handle) is 7 inches or under. Screwdrivers over 7 inches go in checked baggage.

Can I bring a multi-bit screwdriver set on a plane?

If the drivers in the set are each under 7 inches, yes. If the kit includes a full-length driver over 7 inches, that piece needs to go in checked. Precision screwdriver sets (with small electronics drivers) are almost always under the limit.

Can TSA still confiscate a screwdriver under 7 inches?

Yes. TSA agents have final say at the checkpoint. A screwdriver within the size limit can still be flagged if an agent considers it a security risk. This is rare but it does happen, especially for unusually sharp or pointed tips.

Can I bring a screwdriver in checked baggage?

Yes, any size screwdriver is allowed in checked baggage with no restrictions. Wrap or sheathe the tip to protect your bag and the baggage handler.
