Why you need these hex keys: If you are a wheelchair user you need a great set of hex keys. These are the keys we use in our shop every day. They will last a lifetime. We use these hex keys because unlike traditional flat hex keys there are Hex-Plus. That means the hex keys grab the fastener in the corners of the hole, not the sides. So when we get stripped screws in we can often use the Hex-Plus keys to remove them because the corners are still clean and usable. Best we have ever used. Form Wera: Wera's Hex-Plus design helps to keep the screw head intact with narrow contact surfaces. Standard hex designs tend to round out the screw head. Features ballpoint (ball end) on long-arm of L-key to insert the tool quickly into screw and work at an angle in confined spaces Wera's non-wearing material ensures L-keys stay fixed even after frequent removal Each L-key is laser engraved with the size of each tool for easy locating Designed for a long service life and excellent surface protection Wera's unique vacuum ice-hardened process gives the necessary hardness for industrial applications Specifications: Design in German, Make in the Czech Republic Metric Keys: Hex Metric: 1.5 x 90mm* Hex Metric: 2 x 100mm Hex Metric: 2.5 x 112mm Hex Metric: 3 x 126mm Hex Metric: 4 x 140mm Hex Metric: 5 x 160mm Hex Metric: 6 x 180mm Hex Metric: 8 x 200mm Hex Metric: 10 x 219mm * Regular hexagon (not Hex-Plus) SAE (Impartial): Hex Inch (SAE): 5/64" x 100mm Hex Inch (SAE): 3/32" x 112mm Hex Inch (SAE): 1/8" x 126mm Hex Inch (SAE): 5/32" x 140mm Hex Inch (SAE): 3/16" x 160mm Hex Inch (SAE): 7/32" x 180mm Hex Inch (SAE): 1/4" x 190mm Hex Inch (SAE): 5/16" x 200mm Hex Inch (SAE): 3/8" x 212mm
