INGCO Ball Point Hex Key 9 Pcs - HHK12091

The INGCO HHK12091 Ball Point Hex Key 9 Pcs set drives fasteners through a heat-treated Chrome Vanadium steel build. Sizes spanning 1.5mm to 10mm cover most industrial mechanical and furniture assembly requirements. With the long-arm design, this version provides significantly more leverage than the older HHK11091 model.

Key Features

1. 25-Degree Entry: Ball point tip engages fasteners at an offset for tight-space access. Bolt rotation succeeds even without a direct vertical line of sight.
2. Cr-V Construction: Industrial-grade Chrome Vanadium steel resists structural deformation under high torque. Metal won't deform or snap when tackling humid, rusted components.
3. Long Arm Design: Extended length increases the lever arm for easier manual turning. Increased reach hits deep-set fasteners that standard length keys can't touch.
4. Heat-Treated Hardness: High-temperature processing keeps hex edges sharp and prevents rounding of heads. Tools maintain a tight fit in hardware over long-term mechanical use.

Frequently Asked Questions

What is the use of ball point hex key?

Ball points permit wrench entry at angles up to 25 degrees. This allows for bolt rotation in obstructed areas where straight tools fail.

Is INGCO HHK12091 made of S2 steel?

No, this set consists of Chrome Vanadium (Cr-V) steel. This material offers sufficient durability and corrosion resistance for general workshop tasks.
