Please tell me, does anyone have the quality (weight) standards for nuts? I want to know the quality of M20 nuts. This post was last edited by wisdom1010 on 2009-4-17 08:14 ]

Check Mechanical Design Manual M20 Nut Quality: GB/T6170 and GB/T41 are about 51.55g/piece ； GB/T6172.1 and GB/T6174 are about 27.76g/piece. This post was last edited by kingwoo on 2009-4-16 20:00 ]

It is recommended to clarify the question. This includes the material, geometric dimensions, thread accuracy, weight, etc. of the nut. It cannot be accommodated by any one standard.

You can first calculate the volume of the M20 nut to find its mass.

It depends on what standard your nuts are?

It depends on what type of nut your nut is. For ordinary hexagonal nuts, you can check GB/T 6170-2000, GB/T 41, and GB/T 6171.
