Straightflute metric hand taps designed for reliable, accurate internal threading in metal, plastic, and wood applications Key benefits Easier, more consistent internal thread cutting: straight flute geometry guides chips away from the cut and helps maintain alignment during hand tapping. Durable under repeated use: impact and heattreated carbon steel construction delivers strength and hardness for longer tool life. Precise twostep tapping workflow: the finethread tap performs the initial wire tapping, while the coarsethread tap consolidates the thread for accurate final fit. Versatile compatibility: works for a wide range of materials and equipment, reducing the need for multiple specialized taps. Features Tool type: straight flute metric hand tap for internal threads Material: impact and heattreated carbon steel for improved toughness and wear resistance Thread process: includes finethread tap for first wire tapping and coarsethread tap for consolidating wire tapping Applications: suitable for automotive, motorcycle, and machinery maintenance and for working with wood, plastic, and aluminum Practical scenarios Automotive : restore or create internal threads in engine brackets, mounting holes, or body panels when replacing components or repairing stripped threads. Motorcycle maintenance: tap or damaged threads in frame fittings, brake mounts, or accessory brackets for secure fastener installation. Fabrication and prototyping: create consistent internal threads in aluminum housings or plastic enclosures during part production or modification. Why choose this tap set Designed specifically for internal thread work with a twostep fine/coarse approach to ensure accurate, consolidated threads Built from treated carbon steel to withstand repeated tapping tasks in diverse materials Practical for mechanics, maintenance technicians, and fabrication shops who need reliable, repeatable internal threading without specialized equipment Compatibility and notes Metric specification for use with metric fasteners and machines Intended for hand tapping of internal threads in the listed materials and applications
