HARDEN 9-Piece Professional Extra-Long Ball-Point Hex Key Set | 540609

Description

Reach the unreachable with the HARDEN 540609 9-Piece Extra-Long Ball-Point Hex Key Set. Designed for industrial maintenance teams, automotive technicians, and precision engineers, this "Extra-Long" set provides significantly more torque and reach than standard or medium-length Allen keys.

Forged from premium Chrome Vanadium (Cr-V) steel and heat-treated for maximum structural integrity, these wrenches are built for high-stress environments. The extra-long arm design acts as a powerful lever, allowing you to break loose seized or over-tightened bolts with ease. The precision-machined ball-point tips allow the wrench to pivot up to 25 degrees, ensuring a secure "bite" even when the tool cannot be aligned perfectly straight. To prevent stripping, the straight ends are chamfered for a smooth, burr-free fit. The set is housed in a heavy-duty hinged storage case with high-visibility size markings for rapid tool selection.

Key Features & Benefits:

• Extra-Long Reach & Leverage: Extended shaft design provides superior mechanical advantage and access to deeply recessed fasteners.

• 25° Ball-Point Entry: Specialized spherical tips allow for off-angle driving in tight or obstructed areas where a straight wrench won't fit.

• Forged Chrome Vanadium (Cr-V) Steel: Industrial-grade construction provides superior hardness (HRC 52–55) and prevents tip twisting under high torque.

• 9-Piece Metric Range: Includes every essential size from 1.5mm to 10mm for universal compatibility with machinery and automotive fasteners.

• Chamfered Straight Ends: Precision-ground edges on the short arm ensure a snug fit into the bolt head, reducing the risk of stripping.

• Professional Satin Finish: High-quality industrial coating provides exceptional resistance to corrosion, rust, and workshop grease.
