- Hex Dome Acorn nuts can be used alone or as a cap for a hex or jam nut, dome nuts serve a decorative purpose by concealing the threaded end of a fastener or acting as a cover for protruding, perhaps sharp threads. Some types are manufactured in two pieces and pressed together; others are milled from a single piece of metal. Aside from a possible slight difference in dimensions, both types of nuts are otherwise the same
- Also known as: Crown Nut, Blind Nut, Dome Cap Nut, Hex Cap Nuts, Acorn Nuts
- Material / Coating: Stainless Steel A2-70 G304 is the most popular grade of stainless steel. It is aesthetically pleasing to the eye and very practical because of its excellent corrosion protection in most environments. Most products can be identified by the following markings: A2, A2-70, 304 or G304 but not all nuts are stamped. Stainless steels are largely non-magnetic but it is common for some stainless steel fasteners to show a small degree of magnetism which is a result of work-hardening during the manufacturing process
- Can Stainless corrode?: Stainless steel is corrosion-resistant but not corrosion-proof and corrosion can occur if the material is installed or handled incorrectly. The use of tools and drills made from conventional steel during the installation of stainless steel fasteners may also lead to problems. Even the hardest of tools can produce debris that leaves minute steel particles on the stainless steel fastener surfaces or in pre-drilled holes. It is these particles that often rust when exposed to moisture or oxygen and can result in a stained or tarnished finish to the stainless steel material
- Galling: can occur when excessive pressure is used to tighten a nut onto a thread, common with stainless fasteners but can also be an issue with other materials. Fasteners with damaged or fine threads are particularly prone to galling.
Some suggestions to help prevent thread galling:
Tightening the nut more slowly without excessive pressure, will frequently reduce or sometimes solve completely, the problem. As the installation RPM speed increases, the heat generated with friction during tightening escalates the chances of thread galling.
Reduce the friction by applying a suitable lubricant to the thread frequently eliminates thread galling. Typical lubricants are chloride-paraffine, molykoat lacquer, molybdenum disulphide, high pressure oil, graphite, mica, or talc, some assemblies where there is extreme pressure, corrosion resistant grease or waxes may also be effective - Thread Pitch (Metric): is the distance between the peaks of two threads along a screw, bolt, nut or fastener expressed in millimetres (mm). Used when referring to Metric parts. For example, a thread pitch of 1.50mm means that the distance between one thread and the next is 1.50mm
