M20 (20mm) Hex Nut - Steel (Pack of 5)

Product Information

Metric Fine Pitch Hexagon Nuts are available from our online store for applications which require finer adjustments and greater resistance to loosening under vibration. Imperial Hexagon Nuts

Hexagon Nuts are one of the most popular types of fasteners, designed to be used in conjunction with screws, bolts and other male threaded fasteners to securely join multiple components together.

DIN 934 Hex Nut Dimensions (Coarse Threads)

Accu also lists Plastic Hex Nuts in our standard range, with Nylon, Polycarbonate, Polypropylene, Reny and Polyphenylene options available, along with specialist thermoplastics like PVDF and PEEK.

Hexagon Nuts from Accu are manufactured in a wide range of materials. Metal Hex Nuts available include A1, A2, A4 Stainless Steel, with High Tensile options in Duplex and Bumax Stainless Steel. Mild Steel (Grades 6, 8, 10 and 12) is also available with either Hot Dip Galvanised or Zinc Plated finishes. The diameter equal to the external diameter of the threads or the overall diameter of the part. (Nominal diameter is more of a label than a size. For example, a bolt and nut may be described as being ½” diameter. But neither the external threads of the bolt nor the internal threads of the nut are exactly .500 in diameter. In fact, the bolt diameter is a little smaller and the nut diameter a little larger. But it is easier to specify the components by a single size designation since the bolt and nut are mating components.)

The smallest or largest pitch diameter that fits onto a screw or into a nut, including all of the form deviations such as lead, thread angle, taper, and roundness. Functional diameter is a measure of the ability to assemble the thread. This type of metric nut is also commonly referred to as a Full Nut or Finished Hex Nut, and is typically fastened using either a wrench (spanner) or a ratchet. Coarse threads are those with larger pitch (fewer threads per axial distance), and fine threads are those with smaller pitch (more threads per axial distance). Coarse threads have a larger threadform relative to screw diameter, whereas fine threads have a smaller threadform relative to screw diameter.

Pitch is the distance from the crest of one thread to the next or the distance from one thread groove to the next, measured from crest to crest. Pitch is also described as the number of threads per inch. Hexagon Nuts can be manufactured in alternative material types such as Aluminium, Brass, Phosphor Bronze and Titanium on request. Metric Hexagon Nuts For heavy duty applications, such as structuralprojects, Heavy Duty Hex Nuts are available from Accu in both metric and imperial sizes. Metric Hex Nut Materials

DIN 934 Hex Nut Dimensions (Fine Threads)

These components feature a coarse metric thread pitch, which makes them more resistant to cross threading and stripping. A raised, helical rib or ridge around the interior or exterior of a cylindrically shaped object. Threads are found on screws, nuts, and bolts. When combined with a Mating Bolt , a hex nut can be used to fasten two or more parts together through a combination of compression, friction (of the threads of the fasteners), and a slight stretching of the bolt.

Washers are also often used with nuts and bolts to help distribute the load of the fasteners, for spacing or protecting the surfaces of the mating components.
