Review: Good quality but pricey - Just bought the one size to carry on my bike for adjusting the handlebars. Good but pricey!

That's what you get when you buy a better quality tool. ## Features - Klein Tools JTH6 M4 4mm Hex Wrench with T-Lathe ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005G394YO | | Brand | KLEIN TOOLS | | Brand Name | KLEIN TOOLS | | Colour | Multicolored | | Country of Publication | USA | | Customer Reviews | 4.8 out of 5 stars 532 Reviews | | Finish Types | Brushed | | Global Trade Identification Number | 00092644337314 | | Head Style | Hex | | Item Length | 6 Inches | | Item Package Quantity | 1 | | Item Torque | 6.5 Newton Meters | | Item Weight | 0.1 Ounces | | Manufacturer | Klein Tools | | Manufacturer Part Number | JTH6M4 | | Material | Chrome Vanadium Steel | | Material Type | Chrome Vanadium Steel | | Model Number | JTH6M4 | | Operation Mode | Mechanical | | UPC | 092644337314 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** KLEIN TOOLS - **Colour:** Multicolored - **Item Length:** 6 Inches - **Item Weight:** 0.1 Ounces - **Material:** Chrome Vanadium Steel ## Images ![Klein Tools JTH6M4 4mm Hex Key with Journeyman T-Handle - Image 1](https://m.media-amazon.com/images/I/41cGD2FWL4L.jpg) ![Klein Tools JTH6M4 4mm Hex Key with Journeyman T-Handle - Image 2](https://m.media-amazon.com/images/I/61cqeZPYO1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality but pricey *by R***S on 29 September 2023* Just bought the one size to carry on my bike for adjusting the handlebars.
