Hexagon Coupling Nuts
When combined with a screw or stud bolt, hexagon nuts create a screw connection that can easily be tightened and loosened using a wrench. In the case of hexagon coupling nuts, the body and the metric coarse thread are longer than on a normal hexagon nut. The extended length means that components can be joined while maintaining a precise distance between them – like when using hexagon standoffs with female threads.

TITAN offers coupling nuts – also known as spacer sleeves or spacer nuts – in numerous sizes and lengths. They correspond to the hexagon nuts defined in DIN 6334, which comply with standardized specifications regarding their dimensions, tolerances, and thread sizes and ensure compatibility with the counterparts.
Order hexagon coupling nuts in various sizes and designs from TITAN. We will quickly supply your company with the products you need – even in the case of large-volume orders.
Secure connections with hexagon nuts from TITAN
Hexagon coupling nuts are used in a wide range of applications. In the electronic and electrical engineering industry, for example, they are used to join electronic components and enclosures. In the field of circuit board assembly, they allow elements to be fastened together while maintaining a precise distance and can be used to ensure electrical isolation or thermal decoupling. In mechanical engineering, aerospace technology, and the automotive industry, hexagon nuts make it easier to position components precisely.
Order hexagon coupling nuts in line with your requirements
TITAN can provide you with hexagon nuts made from various materials with and without surface treatments. This allows you to tailor the strength and corrosion resistance of the fastening elements to the application in question – depending on whether they are to be used indoors or outdoors, for example. Hexagon nuts made from stainless steel and galvanized steel are available as standard, and other materials such as brass or aluminum are available on request for custom products.

Our low-cost coupling nuts are pressed on state-of-the-art machines – unlike standoffs, for example, which are made using a turning process.
If you are looking for something else, our product range features a number of other nuts, including hexagon coupling nuts with stop and hexagon coupling nuts with inspection holes. All products are available in standard sizes such as M8x30 or M12x35 and in packaging units of up to 200 pieces – with discount scales to save you money!
