This set contains three ergonomic hand-grip caps for M10, M12 and M14 hex nuts.
Each cap features a 9-tooth round grip pattern, giving you strong leverage for tightening or loosening nuts by hand, without needing a wrench.

The inner geometry is tuned for a firm friction snap-fit that stays put during use but can still be removed.
Perfect for tool-free adjustments, quick assembly, jigs, enclosures, machine frames, printers, CNC systems and DIY projects.
