Armstrong | 12 Pt Black Oxide Long Combination Wrench 20mm | 56-220
Access
The Armstrong 12 Pt Black Oxide Long Combination Wrench 20mm features a small head design that allows for easier access in tight areas.
Strength
The Armstrong 12 Pt Black Oxide Long Combination Wrench 20mm is forged from one piece of steel for increased durability. The modified radius corner design in the open end offers greater strength than hex designs. Hex designs concentrate stress in the corners, resulting in possible fracturing under heavy loading. The radius corner design in the box end engages the flats of the fastener, not the corners, providing 15% to 20% more torque. Also prevents rounding of the fasteners and enhances the turning of worn, rounded fasteners - extending fastener life and reducing chance of slippage. The anti-slip notches in open end grip the flats of fasteners providing up to 25% more torque than conventional designs.
Safety
The opening size is stamped at both ends and on both sides in large markings for ease in identification.
