Closed Hand Knobs / Cap Nuts for Tools (M3 to M10)

Low-Profile Closed Hand Knobs / Cap Nuts for Tools (M3 to M10) For many of my tools, I frequently need hand nuts as replacements or upgrades to allow for quick and easy adjustment without hex keys or wrenches. This parametric collection covers all common metric sizes from M3 up to M10. Unlike through-hole models, these feature a closed-cap design meant for shallow applications. The total clearance depth inside the knob is roughly twice the height of the nut, giving your tools a clean, finished look while protecting the protruding thread from dust and damage. Design Features & Assembly: Press-Fit Design: The internal hex slots are designed for a tight, reliable press-fit to secure the nuts firmly in place. Closed-Cap Design: Perfect for clean finishes where the bolt doesn't need to pass all the way through the knob. Mainly Looking for Press-Fit Nut: Designed specifically for standard hex nuts to be pressed directly into the plastic body. Important Note on M10 Sizes (DIN vs. ISO Standards): Depending on your local hardware shop, M10 nuts can vary in size due to different manufacturing standards. To save you from loose fits, I have provided two separate versions for the M10 model: DIN 934 Version: Made for M10 nuts with a larger flat-to-flat width of 16.8mm. ISO 4032 Version: Made for the standard, modern ISO M10 nut dimensions. (Note: All other sizes from M3 to M6 are designed strictly according to standard ISO 4032 dimensions). Available Sizes Included: M3, M4, M5, M6 (Standard ISO) M8 (Standard ISO) M10 - DIN 934 (For 16.8mm flat-to-flat nuts) M10 - ISO 4032 (Standard) Material & Durability: I printed these in PETG for maximum durability, and they have held up beautifully under long-term usage. By using PETG, you don't need to worry about heat degradation or UV degradation over time, making them perfect for workshop or outdoor tools.   I offer all three essential styles: Wing Nuts, Through-Hole Knobs (for bolts of any length), and Low-Profile Closed Cap Knobs (for a clean finish in shallow applications).
