Hex Key Set Sata ST09105ASJ — 9-piece long ball-end Allen keys

Sata ST09105ASJ is a 9-piece long hex (Allen) key set with ball-end tips designed to reach fasteners in confined spaces and at angles. The long shank provides extended reach while the ball-end geometry enables angled engagement up to approximately 25–30 degrees, making access to recessed or obstructed hex sockets easier. The set is intended for use in professional maintenance, assembly and DIY tasks where standard short keys do not provide sufficient reach or clearance.

Advantages

The long shafts increase reach and leverage for tightening and loosening hex fasteners located deep within assemblies. Ball-end tips permit off-axis operation, allowing work at angles when straight entry is not possible. Manufactured from hardened steel for durability, the keys maintain tip profile and resist rounding under typical torque loads. The compact holder keeps the nine keys organized and accessible for quick selection on the job.

Suitable for

• Accessing recessed hex fasteners in machinery and equipment
• Automotive and bicycle maintenance where extended reach is required
• Assembly and disassembly of furniture, cabinets and fixtures in tight spaces
• General workshop and professional repair tasks needing angled engagement

Key specifications

• Set configuration: 9 long hex keys with ball-end tips
• Key type: long arm (extended shank) Allen/hex keys
• Tip style: ball-end for angled entry
• Material: hardened steel construction for wear resistance
• Finish: protective coating to reduce corrosion and provide smoother use
• Storage: compact holding clip/rail for organized transport and storage

How to use

Select the hex key that fits the fastener socket snugly to avoid rounding. Insert the short or long end as appropriate for clearance; use the long shank to reach recessed fasteners and the ball-end when angled access is required. Apply steady torque, taking care not to exceed the tool's capacity—use the straight end for higher torque and the ball-end for positioning or light tightening. Return keys to the holder after use to keep the set organized and to protect tips from damage.

Usage recommendations

For best results, keep contact surfaces clean and ensure the selected key fully engages the fastener before applying torque. Use the ball-end for alignment and low-torque fastening; switch to the straight insertion for final tightening. Store the set in a dry place to maintain the protective finish and inspect tips periodically for wear.
