Tips 1. Before tapping confirm whether the diameter of the round hole is appropriate, and to take protective measures when working. 2. When tapping, it is necessary to add water or coolant to cool down to prevent excessive temperature and reduce tap loss. If it encounters difficulty in rotation, the tapping should be suspended. 3. Be sure to select the appropriate cutting oil for the complex tapping process and apply anti-rust oil for maintenance after use. ## Features - 【Size】Length: 3.54"/90mm, Thread Head: 0.71"/18mm, Square Head: 9.0mm x 9.0mm (L*W), Shank Diameter:11.2mm, Pitch: 20 TPI. - 【Feature】Standard thread design, made of High-speed steel with high hardness and toughness, provide rapid chip removal for efficient threading. - 【Application】use to repair bicycle pedal cranks threads, clean out or restore damaged threads within the crank arms. - 【Usage】Can be used with manual equipment or special processing consoles for tapping, Appropriate addition of coolant can extend the service life when tapping. - 【Package Included】 9/16-20 UN Right Hand Tap * 1, 9/16-20 UN Left Hand Tap * 1. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Aceteel | | Part Number | Tap_9/16_RH&LH | | Item Weight | 5 ounces | | Package Dimensions | 4.88 x 4.13 x 0.83 inches | | Item model number | Tap_9/16_RH&LH | | Batteries Included? | No | | Batteries Required? | No | ## Images ![Right and Left Hand 9/16"-20 UN HSS Tap, 9/16 x 20 UN Thread Tap for Bike Crank Repair - Image 1](https://m.media-amazon.com/images/I/61B7wC+nS7L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great bargain , I’d buy again! *by B***S on August 16, 2025* Good price point on these for chasing threads. Came in nice little plastic box to keep them in. Works great on aluminum crank arms on bicycles. ### ⭐⭐⭐⭐⭐ The right product for cutting threads for bicycle pedals. *by B***B on July 10, 2025* Cut threads properly , not sure how long they will last but I’m only going to use them once. (I hope). ### ⭐⭐⭐⭐⭐ Good bicycle tool to have when needed *by J***L on March 25, 2025* My Left crank arm, left pedal left handed thread got compromised. This 9/16 Tap set cut the threads back to normal. The Taps are Not marked Left or Right. The Left handed thread tap has additional markings on the side of the tap more than the right handed thread tap does. A couple of drops of oil on the threads helps during the thread clean up process. ## Frequently Bought Together - Aceteel Right and Left Hand 9/16"-20 UN HSS Tap, 9/16 x 20 UN Thread Tap for Bike Crank Repair - Tap Magic 30004P ProTap Cutting Fluid, 4 oz.
