U.S. Transportation Security Administration guidance: tools longer than 7 inches are not allowed in cabin bags. Measure from the tip of the shaft to the furthest point of the handle; items exceeding 7 inches must travel in the hold. Screening officers retain final authority at checkpoints.
Many European and international operators apply stricter limits and routinely require tools to be transported in checked baggage. Several carriers explicitly prohibit metallic repair implements in cabin bags and will confiscate them at security – verify the carrier’s restricted-items page before departure. When uncertainty remains, place items in checked baggage or arrange shipment.
Battery-powered drivers present additional constraints: lithium‑ion cells spare to the device must remain in the cabin with terminals protected; installed batteries may still be subject to airline policy. Cells between 100 Wh and 160 Wh require airline approval; over 160 Wh are usually forbidden. Check watt‑hour ratings printed on batteries and the carrier’s battery rules.
Practical checklist: measure length and record in cm/in; sheath or tape exposed tips; pack in a rigid case or tool pouch; keep metal implements away from sharp‑edged packing that could trigger inspection. Declare items at check-in if placing them in checked baggage. Expect possible confiscation, fines, or denied boarding for noncompliance – confirm rules at least 48 hours before travel.
US TSA: Drivers under 7 inches in carry-on
Allowed in carry-on if overall length (tip to rearmost point of the grip) measures less than 7 inches; items 7.0 inches (17.78 cm) or longer must be placed in checked baggage.
- How length is measured: from the tip of the shaft to the farthest point of the grip when fully assembled; round fractions to the nearest hundredth of an inch for accuracy.
- Examples typically permitted in cabin: precision/ jeweler’s drivers, compact flathead or Phillips drivers under 7″ total length, individual hex or Torx drivers shorter than 7″.
- Examples typically prohibited from cabin: full-size drivers with shafts ≥7″, long-shaft multi-bit driver assemblies exceeding 7″, fixed-shaft pry/driver hybrids longer than 7″.
- Multi-tools: allowed only if any extended driver component remains under 7″; integrated long shafts that exceed the limit must go in checked baggage.
- Final screening authority rests with TSA officers at the checkpoint; an item measuring under 7″ may still be flagged for additional inspection or refused based on construction (e.g., heavy metal shafts shaped for prying).
Practical recommendations
- Measure items before travel with a rigid ruler or caliper; keep a printed measurement if uncertain.
- Pack drivers under 7″ in a single transparent pouch or dedicated tool roll to speed screening.
- If length is borderline or construction is heavy-duty, place the item in checked baggage to avoid confiscation and delays.
- Check airline and foreign airport rules ahead of departure–some carriers enforce stricter limits than TSA.
Presenting small repair tools at security to reduce risk of confiscation
Place the metal repair tool in a transparent, sealable pouch and keep that pouch in an easily accessible outer compartment of the carry-on; show the pouch to the screening officer before placing the bin on the conveyor.
Remove interchangeable bits and fasteners, align them beside the shaft inside the same pouch, and mark the maximum exposed metal length with a piece of tape labeled in inches or centimeters; take a quick photo of the labeled layout with a phone as backup evidence of intent.
Include proof of legitimate purpose in the same pocket: purchase receipt, manufacturer manual, service order, or project photos referencing the item’s serial number; these documents reduce ambiguity during a manual inspection.
Lay the clear pouch on top of clothing and electronics in the screening bin so the X‑ray produces an unobstructed silhouette; avoid wrapping the item in opaque fabric or placing it inside dense cases that produce confusing images.
If an officer requests closer inspection, open the pouch and point to the documentation and separated bits; offer to demonstrate that the tool has no power source, batteries, or modifications that could suggest hostile intent.
Choose a bag with an external zip pocket or a removable organizer with a transparent panel to streamline presentation – see best messenger bag companies for suitable models and features that speed security checks.
For longer shafts or when avoidance of screening risk is desired, consider shipping the item ahead or storing it at destination; for compact storage options at home or at a job site, review solutions at best umbrella stand for large umbrella.
Comparing carry-on tool rules: EU vs UK vs Canada
Recommendation: Place manual fastening tools in checked baggage for trips involving the EU, the UK or Canada; if cabin carriage is unavoidable, secure written approval from the airline or departure airport security before arrival at the checkpoint.
European Union
No single EU-wide allowance exists: Regulation (EU) 2015/1998 sets a framework, but national civil aviation authorities and individual airports publish the operative prohibited-items lists. Practical consequences: some airports allow very small, blunt fastening implements after secondary screening, while others enforce a zero-tolerance policy and will seize metal tools at the gate. For intra-EU and Schengen transfers, the strictest airport on the itinerary dictates outcome; confirm the departure airport’s security page and the airline’s cabin-item policy in writing when planning to board with a tool.
United Kingdom
The UK enforces Department for Transport/CAA guidance aligned with ICAO; major hubs typically treat metal hand tools as prohibited in cabin cabins unless explicitly authorised. Ground handlers and airline staff hold discretionary removal authority; when pre-approval exists, expect detailed inspection and potential conditions (e.g., blade or shaft immobilised). Absent pre-approval, prepare for immediate confiscation and related travel delay.
Canada’s screening authority, CATSA, lists tools among items subject to cabin prohibition if they could be used as weapons. Enforcement is generally consistent nationwide but frontline officers make the final call. For itineraries beginning in Canada and continuing internationally, checked baggage storage removes ambiguity; if cabin carriage is essential, present manufacturer documentation and prior airline confirmation to reduce risk of seizure or denied boarding.

Practical alternatives: checked baggage, shipping or buying a driver at destination
Place the driver in checked baggage when airline policy and itinerary permit; this minimizes risk of seizure at security and complies with most national aviation authorities for metal tools.
Packing for checked baggage
Acceptable: most carriers and regulators (TSA, EASA, UK CAA, CATSA) permit manual drivers in checked bags without strict length limits. Wrap the tool in a rigid case or a padded sheath; immobilize sharp tips with tape or a rubber cap; place inside a hard-sided suitcase or between clothing layers to prevent movement. For powered drivers, remove rechargeable lithium batteries and carry them in cabin carry-on (spare cells must be in cabin per IATA rules); if batteries remain installed, verify carrier policy before travel. Mark oversized tool boxes in advance with the airline if they exceed standard dimensions or weight limits; expect checked-bag fees if adding extra pieces.
Shipping vs buying at destination
Shipping: use tracked courier (USPS Priority/FedEx/UPS) with insurance and a clear customs declaration as “tools” (HS code 8205 often applies). Domestic ground rates for small parcels typically start around $5–$15; international economy from ~$30 upward depending on weight and destination. Pack in a rigid box with foam, sign for delivery when available, and declare accurate value to avoid customs delays or penalties. Customs duties and VAT may apply at destination; small low-value shipments often clear with minimal fees but expect processing time of several days to weeks for international routes.
Buying locally: airport shops sell basic drivers at inflated prices; major hardware chains (Home Depot, Lowe’s, Screwfix, B&Q, Leroy Merlin) and independent stores offer a wider selection at standard retail prices. Typical price points: single cheap driver $3–10, compact multi-bit sets $10–30, branded multi-piece kits $30–100. Advantages: immediate availability, correct regional screw head types (metric vs imperial), and no transport restrictions. Alternatives include tool rental services, community tool libraries, or borrowing from hotel maintenance for short-term needs.
Recommendation summary: for planned trips, pack the driver in checked baggage with proper casing; for long shipments or bulk quantities, use insured tracked courier with customs paperwork; for urgent or one-off needs at destination, purchase a budget multi-bit set from a local hardware outlet or rent locally.
