Hex Key Set Bondhus long ball-end 1.5–10 mm (10 pcs)

Bondhus long ball-end hex key set contains ten hex keys in sizes 1.5–10 mm designed for tasks that require extended reach and angled access. Each key is manufactured from chrome-vanadium steel for high strength and wear resistance. The long shafts provide additional reach and leverage while the ball-end profile permits engagement of fasteners at angles up to approximately 25°, making these tools suitable for tight or obstructed spaces encountered in assembly, maintenance and repair work.

Advantages

The long ball-end geometry enables insertion and turning of hex fasteners at an offset angle, reducing the need to align the tool perfectly with the fastener head. Chrome-vanadium construction delivers durability and resistance to deformation under torque. The set covers a common range of metric sizes from 1.5 mm to 10 mm, allowing use across a variety of applications. Long shafts increase reach into recessed or hard-to-reach fasteners and provide improved leverage compared with standard-length keys.

Suitable for

• Assembly and tightening of machinery and equipment where space is limited
• Bicycle maintenance and repairs involving internal or recessed bolts
• Furniture assembly requiring extended reach into deep joints
• Electronics and small-appliance service where angled access is needed

Key specifications

• Set composition: 10 hex keys, metric sizes 1.5, 2, 2.5, 3, 4, 5, 6, 8, 9, 10 mm
• Tip profile: ball-end on long shaft for angled entry (up to ~25°)
• Material: chrome-vanadium steel for strength and wear resistance
• Shaft type: long shaft design for extended reach and leverage

How to use

Select the hex key that matches the fastener size and insert the ball end into the screw head. If direct alignment is blocked, engage the ball-end at a slight angle—up to approximately 25°—and apply steady torque. For maximum control and to avoid rounding the fastener, ensure the key is fully seated before turning. Use the long shaft for reach into recessed locations or for extra leverage when loosening and tightening fasteners.

Usage recommendations

Inspect fasteners and hex key tips regularly for wear or damage. Apply controlled torque within the limits of the fastener and tool; where high torque is required, use the appropriate size and support to prevent slippage. Store the set dry and clean to preserve the finish and prevent corrosion.
