Vít và Đai ốc M20-1 Ren Mịn

This set includes a metric M20-1 screw and a matching hex nut with internal thread. Both parts are optimized for 3D printing and are great for prototyping, mechanical projects, or demonstration purposes.

Recommended Print Settings:
– Layer height: 0.2 mm
– Infill: 50–100% depending on required strength
– Material: PLA, PETG, or ABS
– No support needed

Notes:
The threading has been tested and fits well with proper printer calibration. If the fit is too tight or loose, try adjusting the scale by ±1%.

This is an M20 × 1.0 fine thread, not the standard M20 × 2.5. It offers a tighter fit and is ideal for applications requiring greater precision or vibration resistance.
