About this nut
This is a nut in Q235 Carbon Steel, at strength class Grade 4, supplied white zinc plated. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.
A nut is the closing half of a bolted joint. Its property class is chosen to match the bolt it is paired with — a class 8 nut for a grade 8.8 bolt, so the thread strips before the bolt breaks. Used wherever a bolt or stud has to be tightened from the far side, and for locking and positioning duties on machinery and steelwork.
Q235 is the standard Chinese structural carbon steel, roughly equivalent to S235JR / A36. Used for general-purpose bolts and anchors where a defined high strength grade is not required.
White (clear) zinc plating is the standard bright electroplated finish, typically 5–12 µm. Good for indoor and sheltered use.
Sold by the piece, so one is a valid order. Stock lines leave our warehouse within 24–48 hours of cleared payment, and freight is calculated at checkout from the packed weight and the destination.
