Great for 3D printer assembly

Bought this for assembling my new 3D printer. The tolerances are good, and the washers slide onto the bolts smoothly without being too loose.

Essential for bike maintenance

Used these for tightening bolts on my bicycle accessories. They fit perfectly and haven't shown any signs of rust after a few weeks of outdoor use.

Perfect assortment for electronics

Exactly what I needed for my small electronics projects. The M2 and M2.5 sizes are hard to find locally, so this kit is a lifesaver. The steel quality feels solid.

Good value, nice case

The washers are good quality and the plastic organizer box keeps everything neat. I deducted one star because there were slightly fewer M3 washers than I expected, but overall great value.

Clean and precise

Very clean finish with no burrs or sharp edges. They sit flat against the surface as they should. Highly recommend for hobbyists.

Q: Is the storage box durable?

A: The kit comes with a sturdy plastic compartmentalized box designed to keep the different sizes organized and prevent them from mixing together.

Q: Does the kit come with screws or just washers?

A: This specific product listing is for flat washers only. It does not include screws, bolts, or nuts.

Q: What is the outer diameter of the M4 washer?

A: The standard outer diameter for an M4 flat washer is typically around 9mm, with an inner hole of 4.3mm to fit the M4 bolt comfortably.
