Square nuts are designed to provide solid joints in projects subject to high mechanical loads and tensile stresses. Their four-sided shape facilitates the use of standard tools and ensures stable tightening, as well as offering a wider support surface that improves load distribution and increases fastening strength. They are commonly used in metal structures, carpentry, ship and bridge construction, as well as industrial and agricultural applications that require high-strength nuts.
Square nuts according to DIN standard
We have different models of DIN square nuts, manufactured in steel, A2/A4 stainless steel and brass, with mechanical qualities 04-17H, 05-22H, 6, 8 and HV 350-450. They are also supplied with protective finishes in black, zinc-plated or hot-dip galvanised, to adapt to different environments and offer high corrosion resistance.
- DIN 557 square nuts: manufactured in steel or A2 stainless steel, with the option of a zinc-plated finish. They provide a firm and stable grip and are widely used in wood joints and metal structures.
- Weldable nuts DIN 928: square in shape, they are designed to be welded directly to the part, creating permanent and resistant joints. Available in steel (BU) and A2 stainless steel.
- Weld nuts DIN 929: with square geometry and an optimised support system, they guarantee a solid and durable anchorage in highly demanding structures. They are available in steel (BU) and A2 stainless steel.
All our DIN square nut references have different mechanical qualities (04-17H, 05-22H, 6, 8 and HV 350-450) and are available in black, zinc-plated or hot-dip galvanised finishes, which provide protection against corrosion and ensure excellent performance in any environment.
