Square Nuts DIN 562
Our Square Nuts are manufactured from durable stainless steel to DIN 562 standards, providing a compact and corrosion-resistant fastening solution for a wide range of engineering, manufacturing and assembly applications. Also known as thin square nuts, flat square nuts or four-sided nuts, these threaded fasteners feature a low-profile design that makes them particularly useful where installation space is restricted or a conventional hexagonal nut may be unsuitable.
Designed for use with compatible metric bolts, screws and threaded rods, our stainless steel square nuts feature four flat sides that allow them to be held securely against suitable surfaces or within matching recesses. Their square profile can help prevent unwanted rotation during tightening, making them a practical choice for machinery assembly, metal fabrication, furniture manufacturing and general industrial fastening. The stainless steel construction also provides resistance to rust and corrosion, making these square nuts suitable for applications where moisture exposure or long-term durability must be considered.
Our DIN 562 square nuts are available in a selection of metric thread sizes to suit different fastening requirements. Their reduced thickness makes them suitable for compact assemblies, restricted spaces and applications where a low-profile threaded connection is required. When selecting square nuts and bolts, it is important to ensure that the thread sizes and pitches are compatible and that the selected fasteners meet the mechanical requirements of the installation.
Key Features & Benefits of DIN 562 Square Nuts
- Stainless Steel Construction – Provides corrosion resistance and durability for suitable industrial and engineering applications

Common Applications for Stainless Steel Square Nuts
Thin square nuts are commonly used in applications where a compact threaded fastener is required. Their four-sided profile and reduced thickness make them suitable for a variety of mechanical assemblies and fastening arrangements.
- Machinery Assembly – Securing suitable components, brackets and equipment fittings using compatible threaded fasteners
- Metal Fabrication – Providing threaded connections within fabricated metal components and assemblies
- Furniture Manufacturing – Fastening suitable frames, brackets and structural fittings where a compact nut is required
- Electrical Equipment – Securing compatible mounting brackets, panels and equipment components
- Construction & Engineering – General-purpose fastening in suitable metalwork and mechanical assemblies
- Recessed Fastening – Using the square profile within compatible slots or recesses to help prevent rotation
- Threaded Rod Assemblies – Providing a compact fastening option for compatible metric threaded rods
DIN 562 Square Nut Dimensions & Sizing
When choosing a DIN 562 square nut, the main dimensions to consider are the metric thread size, width across flats and overall nut thickness. These measurements determine whether the fastener will fit the intended bolt or threaded component and whether sufficient space is available for installation.
Unlike standard-height square nuts, DIN 562 fasteners feature a thinner profile. This makes them useful for applications where space is limited, although the reduced thickness must also be considered when assessing thread engagement and the required fastening strength.
For accurate square nut dimensions, refer to the individual product specifications and size information in the product table below. Always confirm the thread pitch, material grade and dimensional compatibility before installation.
DIN 562 Square Nuts vs Other Square Nut Styles
Different square nut designs are available for specific fastening requirements. While DIN 562 square nuts are designed with a thin profile, alternative standards provide different dimensions and installation features.
- Square Nuts DIN 562 – Thin square nuts designed for compact fastening arrangements and restricted installation spaces
- Chamfered Square Nuts DIN 557 – Square nuts featuring a chamfered profile for general mechanical fastening applications
- Square Weld Nuts DIN 928 – Weldable square nuts designed to create fixed threaded connections on suitable metal surfaces
Choosing the correct square nut depends on the required thread size, nut thickness, installation method and the mechanical demands of the assembly.

Frequently Asked Questions
Yes. Their four-sided design allows them to fit into appropriately sized square recesses or retaining features. This can help prevent the nut from rotating while a compatible bolt or screw is tightened.
Measure the internal thread size, the width across the flat sides and the overall thickness. These dimensions are important for selecting a compatible fastener and ensuring the nut fits the available installation space.
Not necessarily. Thin square nuts have less thread engagement than comparable full-height nuts, which can affect their load-bearing capability. The appropriate nut should be selected according to the required fastening strength and application conditions.
