A1: DIN 562 specifies a Flat or Thin Square Nut (also commonly called a Square Jam Nut). Its defining characteristic is its reduced height, typically about two-thirds the thickness of a standard square nut. This low-profile design makes it ideal for applications with limited clearance.
Primary Function: Designed to be used with bolts or screws in unthreaded holes, typically within channels, slots, or square openings where the nut's square shape prevents rotation, eliminating the need for a separate locking feature.
Key Design Feature: Unlike many nuts, it has no chamfered edges, allowing the entire bottom surface to sit completely flat against the mounting material. This provides maximum surface contact and stable bearing pressure.
Common Application: Often used in pairs ("jammed" together) in assemblies to lock a threaded component in a precise position along its length. Their broad, flat sides also make them easy to grip and turn with a standard wrench.

|
Stainless Steel A2 (18-8) |
Good corrosion resistance, suitable for humid, damp, and washdown environments. |
The standard choice for most low-clearance applications requiring rust resistance, such as in food processing equipment, architectural fixtures, or outdoor frameworks. |
|
Carbon Steel (Zinc-Plated or Plain) |
Economical and strong, with plating offering basic corrosion protection. |
General industrial use in dry or protected environments where cost is a primary consideration. |
