Specification Brand : HARFINGTON BulletPoint1 : Size - Box End Size: 21mm / 0.83", 22mm / 0.87"; Total Length: 230mm / 9.06"; Handle Thickness: 6.8mm / 0.27"; Handle Width: 16.7mm / 0.66"; Package Content: 1 x Box Wrenches. BulletPoint2 : Material - The box wrench is made of the preferred Carbon Steel, which has high hardness, strength, and good wear resistance. It is lightweight but durable and is very suitable for working environments that require greater force. It is polished chrome-plated, with a smooth and flat surface, not easily scratched or worn, and rust-proof and corrosion-resistant to extend its service life. BulletPoint3 : Feature - Use the half-moon box end wrench to get around corners or other obstacles easily, maximize access to tight and hard-to-reach areas, and make work easier. The 12-point double head firmly grasps the flats of the fastener head, not the corners, to prevent rounding and increase the contact area and locking groove, which is convenient for protecting your project and yourself. BulletPoint4 : Application - The compact double-head design can be widely used for tightening or loosening nuts and bolts in many narrow spaces. Suitable for DIY handicrafts, home repairs, mechanical repairs, plumbing repairs, automotive repairs, and most general repairs. BulletPoint5 : Note - Make sure to use a double-ended wrench that matches the size of the screw or nut to avoid damage or slippage; when using an offset double box end wrench, make sure the angle of the wrench is aligned with the bolt or nut for better force transfer and operation.
