TOPEX niittimutteripihdit niittimuttereille M3, M4, M5, M6, M8

Most hand riveters struggle with larger steel rivet nuts, but this TOPEX model sets M3 through M8 sizes in one tool thanks to a compound leverage system that multiplies your hand force. The high-strength carbon steel body and chrome-molybdenum mandrels withstand daily workshop abuse, while the black oxide finish keeps corrosion at bay. Five interchangeable mandrels and a dedicated wrench come packed in a blow-molded case for quick size changes and organized storage.

Highlights

• Sets M3, M4, M5, M6, and M8 rivet nuts
• Compound leverage reduces hand fatigue
• Chrome-molybdenum mandrels for long life
• Works with aluminum, steel, and stainless steel rivet nuts
• Ergonomic PVC/rubberized grips for comfort

In daily use

Whether you are repairing automotive brackets, assembling metal furniture, or fabricating enclosures, this tool gives you a reliable threaded anchor in sheet metal, tubing, or plastic. The two-piece jaw system grips the rivet nut securely, and the straight head reaches into flat and moderately recessed areas. At 360 mm long, it provides enough leverage for M8 stainless inserts without becoming unwieldy in tight spaces. The black oxide coating keeps the tool clean and rust-free even in humid environments.
