HAZET 630/8 conjunto de chaves de caixa dupla, métrico 6-22 mm, 8 peças, cromo-vanádio, 12 pontos, DIN 3110

Where ordinary wrench sets stop at the most common sizes, the HAZET 630/8 pushes into the full working range a professional sees daily. Eight double box-end wrenches cover 6x7 through 20x22 mm, each with a 12-point bi-hexagon profile on both ends. That geometry grips fasteners evenly and allows repositioning in 30° increments, while the 15° offset head clears obstructions and saves your knuckles in tight engine bays.

Highlights

• Eight metric sizes: 6x7, 8x9, 10x11, 12x13, 14x15, 16x17, 18x19, 20x22 mm
• Chrome vanadium steel, hardened and tempered, with mirror-like chrome plating
• 12-point (bi-hexagon) box ends on both sides for secure grip and fine repositioning
• 15° offset angle on each head improves access over flat surfaces and around obstructions
• Complies with DIN 3110 and ISO 10102 for dimensional accuracy and torque performance
• Slim, flat heads slip into recessed areas where bulkier tools cannot reach
• Supplied on a sturdy plastic holder that keeps the set organised in a drawer or service cart
• Made in Germany by HAZET, a brand trusted in professional workshops since 1868

In daily use

Imagine a brake caliper bolt tucked behind a suspension arm, or a hydraulic line fitting that only a thin ring end can reach — that's where this set earns its keep. The flat, slim profile lets you get onto fasteners that open-end wrenches would round off or simply cannot access. From routine maintenance to complex repairs, the 630/8 delivers the fit, finish, and leverage professionals expect from HAZET.
