High-Quality Ball End Hex Metric L-Key Set - Precision Metric Hex Wrenches for DIY, Automotive & Machinery Repair - Perfect for Tight Spaces & Hard-to-Reach Fasteners

I bought this to replace a broken one in my set. It's the only part number from Wiha that I can find for this size wrench in this material and finish, so I thought that meant it was a match. Every other one in my set has a snap ring on the ball end that helps it lock into a loose screw but this did not. It works, but I'm not pleased that it's so difficult to find the correct replacement part number.
