  • Size - Open end: 5.5mm / 0.22"; Open outside width: 17mm / 0.67"; Total length: 66mm / 2.6"; Stem thickness: 1.5mm / 0.06"; Stem width: 10mm / 0.39"; Color: Silver-grey; Package includes: 10 x Single open-end wrenches. The open wrench set is thin enough to work on tight spots.
  • Long Lasting - Our single open-end wrench is made of an iron plate, which has high hardness and excellent corrosion resistance. The surface galvanizing improves its wear resistance, keeps its surface smooth and reduces wear, is not easy to deform, and can be used for a long time.
  • Standard Size - The standard open-end wrench's increased thickness ensures a more secure grip on nuts and bolts, resulting in better torque transfer and less slippage. The precision socket allows for quick and easy adjustment of the wrench size to accommodate different bolt sizes. The ultra-thin handle is comfortable to hold and improves work efficiency.
  • Wide Application - Mainly used to tighten or loosen nuts and bolts with flat sides, especially when a socket wrench or adjustable wrench cannot reach them due to space constraints. It is widely used in automotive repair, plumbing, furniture assembly and repair, mechanical repair, construction and DIY projects.
  • Note - Please use a caliper to measure the opposite sides of the screw and nut before purchasing, and then choose the corresponding open-end wrench. Always use the correct size wrench to avoid rounding the bolt head or damaging the wrench.
