- Hex Slotted nuts are a hex nut with six large slots 60° apart in the top center of each flat (side). Their strength is said to be 80% of "full thickness nuts of the same size, style and grade." Slotted nuts are used with bolts and studs that have a hole drilled in their threaded section through which a cotter pin is inserted to prevent the nut from rotating. The nut is quite effectively retained until the pin is removed or shears. They are commonly used to secure the position of wheel bearings on spindles. Slotted nuts may be interchanged with castle nuts, although slotted nuts have a lower profile because they do not have the cylindrical top. They are not used with lock washers
- Also known as: Spindle Nuts
- Material / Coating: Zinc Plated is the most common fastener of plating due to its the low cost and shinny bright silver finish. A thin layer of zinc is applied by either electroplating or mechanically. It is intended to be used internally. Whilst some people use it externally it isnt recommended if corrosion is a concern. If you want a fastener that will withstand the outdoor elements choose from our Stainless steel range
- 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
