Q1: Which tap sizes does this Tap Wrench No. 0 accommodate?
A1: The wrench accommodates taps with a square shank between 2.0 mm and 5.0 mm. This typically covers common metric taps from M1 to M8, but you should always check the specific square dimension of your tap.
Q2: What is the benefit of the steel version over a die-cast version?
A2: The steel version offers significantly higher strength and breaking load than die-cast variants. This is particularly important for higher torque applications, such as when cutting larger threads or working with tough materials.
Q3: Can I use this wrench for non-metric threads (e.g., UNC/UNF)?
A3: Yes, the wrench accepts any tap whose square shank fits within the clamping range (2.0 to 5.0 mm), regardless of the thread standard (metric, UNC, Whitworth, etc.).
Q4: What does the DIN 1814 standard mean?
A4: DIN 1814 is the German industrial standard for adjustable tap wrenches. It defines the dimensions and technical requirements, ensuring that the wrench size (like No. 0) correctly matches the square shanks of corresponding taps.
Q5: How do I maintain my tap wrench?
A5: After each use, clean the wrench thoroughly of chips and cutting oil. Store it dry to prevent corrosion. The adjusting screw and movable parts should be oiled occasionally to ensure smooth operation.
