Frequently Asked Questions

Q: What module size are these brass worm gears, and what does that mean?

A: These worm gears have a 0.5 module (0.5M). Module is a standard metric measurement that defines the size of gear teeth — a lower module number means smaller, finer teeth. A 0.5 module is ideal for miniature and precision gear applications where compact size and smooth motion are required.

Q: What shaft diameter do these worm gears fit?

A: Depending on the model selected, the inner bore (hole aperture) is 1.98mm, 2mm, or 1.5mm. These are designed for a tight, press-fit onto compatible shafts. Please verify your shaft diameter before ordering to ensure a secure fit.

Q: Are these worm gears suitable for robotics or DIY electronics projects?

A: Yes — the compact outer diameter (6–7mm), standard 0.5 module tooth profile, and precision brass construction make these worm gears an excellent choice for robotics, small motor drives, model engineering, and DIY electronics projects that require reliable, low-backlash motion transfer.

Q: What is the difference between the available size variants?

A: There are three variants: W682A (6mm OD, 8mm height, 5°43′ spiral angle, ~1.98mm bore), W6102A (6mm OD, 10mm height, 5°43′ spiral angle, 2mm bore), and W6152A (7mm OD, 15mm height, 4°46′ spiral angle, 1.5mm bore). Select the variant that best matches your gear system's shaft size and required engagement length.
