Torx (TX) L-key set Bondhus BO31834, long, sizes TX9–TX40, 8-piece

Long Torx (TX) L-key set Bondhus BO31834, long, sizes TX9–TX40, 8-piece is a compact toolkit intended for accessing and turning Torx fasteners in recessed or hard-to-reach areas. The set contains eight long L-shaped keys that provide additional reach and improved leverage compared to short keys, suitable for tasks where depth or clearance prevents the use of standard keys. The Bondhus design focuses on accurate fit and consistent torque transfer when engaging Torx heads.

Advantages

The long L-key profile increases reach while maintaining torsional strength, reducing the need to disassemble surrounding components to access fasteners. Each key is sized to match common Torx fasteners, offering a precise fit that minimizes cam-out and wear on screws and tools. The compact set is easy to store in a toolbox or carry to the workplace, and the uniform L-shape allows both high-torque and delicate turning operations depending on grip and leverage used.

Suitable for

• Automotive maintenance and repair where fasteners are recessed or require extra reach
• Mechanical and industrial assembly or disassembly of equipment with Torx fasteners
• Service and fieldwork needing a compact, portable set of long Torx keys
• Workshop tasks that require precise fit and reduced cam-out on Torx screws

Key specifications

• Tool type: Long L-shaped Torx (TX) keys
• Material and finish: durable tool-grade steel with corrosion-resistant treatment (manufacturer-standard)
• Sizes included: TX9, TX10, TX15, TX20, TX25, TX27, TX30, TX40
• Set count: 8 pieces providing a range of common Torx sizes
• Design feature: extended leg length for enhanced reach and leverage

How to use

Select the Torx key that corresponds to the fastener size, insert the short end into the fastener for access into deep recesses or use the long arm for reach and leverage as needed. Apply steady, even torque and ensure the key is fully seated in the fastener before turning to reduce the risk of rounding. For high-torque needs, use the long arm as a handle and the short arm as the driving blade; for confined space work, use the short arm for insertion and the long arm for turning.

Usage recommendations

Inspect keys and fasteners for wear before use, keep the set clean and dry to preserve the finish, and avoid using excessive impact or cheater bars that could damage the tool or fastener.
