Hex Key with Ball End 3.0 mm, Dedra, CRV, long

Long hex key (Allen wrench) with a 3.0 mm diameter and ball end from Dedra, made of chrome-vanadium (CRV) steel. The tool combines a long arm for extended reach and improved leverage with a ball end that permits angled engagement, allowing access to hex fasteners that are slightly offset from a straight approach. It is intended for tasks that require a precise 3.0 mm hex driver, such as assembly, maintenance and minor repairs on furniture, bicycles, machinery and electronic devices.

Advantages

The CRV construction provides durability and resistance to wear while preserving the tool's shape under load. The long shaft increases reach and torque compared with standard short keys, making it easier to work in recessed or hard-to-reach areas. The ball end allows insertion at an angle of several degrees, enabling faster engagement with fasteners that are not perfectly aligned. The simple, single-piece design is low-maintenance and suitable for repeated professional or home use.

Suitable for

• Assembly and tightening of 3.0 mm hex fasteners in furniture and fittings
• Bicycle adjustments and component maintenance requiring a 3.0 mm hex key
• Maintenance and minor repairs of machinery with small hex screws
• Electronic devices and appliances that use 3.0 mm hex bolts

Key specifications

• Hex size: 3.0 mm
• Design: long arm with ball end
• Material: chrome-vanadium (CRV) steel
• Functionality: angled access via ball end; extended reach and torque via long arm
• Finish: corrosion-resistant workshop finish (typical for CRV tools)

How to use

Insert the hex key into the hex socket of the fastener, using the straight end for direct engagement when clearance allows. To access fasteners at an angle or in confined positions, use the ball end which tolerates angled insertion; apply steady pressure and turn the key to tighten or loosen the fastener. Use the long arm for greater leverage when higher torque is required, and switch to the short arm for faster turning when clearance permits. Inspect the hex recess and tool tip before use to avoid rounding the fastener.

Usage recommendations

Use the long hex key for tasks that require reach or angled access; avoid excessive torque beyond hand force to prevent tool or fastener damage. Keep the tool clean and store it dry to maintain the CRV finish and performance.
