Zoro Select M20 Hex Nut Class 10
Zoro Select M04122.200.0001 is a steel hex nut rated to Class 10 with a zinc yellow finish. It uses a metric M20 thread with a 2.50 mm pitch and conforms to DIN 934 dimensional standards. The nut measures 30 mm across the flats and 16 mm in height. Packs contain ten pieces.
Suits metric M20 fastening jobs needing high
Builders assembling structural steel, heavy machinery or automotive chassis where Class 10 proof load is specified will find this nut appropriate. Buyers who need a finer thread pitch, a left-hand thread direction or a different strength class should look at other options. The small pack quantity may not cover large-scale production runs.
Simple hand or wrench installation on clean threads
A standard 30 mm spanner or socket engages the hex flats for tightening to the required torque. Common issues include cross-threading if the bolt is misaligned, insufficient torque leading to loosening under vibration, or galling on stainless counterparts. California Proposition 65 warnings apply to chemicals in the coating.

Questions about this item
What bolt thread size must I already have for the M20x2.50 hex nut to fit?
You need a metric M20 bolt with a 2.50 mm pitch; the nut follows DIN 934 dimensions and a right-hand thread.
Can I use this Class 10 steel nut with older Grade 8.8 bolts I already keep in stock?
The Class 10 nut is stronger than Grade 8.8 bolts, so the bolt will remain the limiting factor in the joint.
How do I confirm the nut meets the DIN 934 standard after installation?
Check that the hex width measures 30 mm, the height is 16 mm, and the yellow zinc finish is intact.
