This professional straight-handle tap wrench is engineered for durability, accuracy and secure grip when cutting internal threads. Manufactured from all-steel, hardened and tempered bodies, it features a solid construction with hardened, ground jaws for reliable clamping of taps. The knurled, fixed handles provide excellent grip and control, even in oily or demanding workshop conditions, while the straight-handle bar design delivers greater leverage, particularly with larger diameter taps. Suitable for tap squares from 4 mm to 10 mm and compatible with ISO 529 tap sizes, this tap wrench is ideal for metalworkers, engineers, and maintenance professionals who require consistent, precise thread cutting performance in both professional and DIY applications.
