- Hex Thin Lock nuts are also referred to as lock or jam nuts. The correct use of a thin nut is to install it under the larger nut. The thin nut deforms and creates a locking action on the thread as the larger nut is tightened. Therefore the thin nut is more effective when it is soft
- Also known as: Hex Jam Nuts, Jam Lock Nuts, Half Nuts
- Material / Coating: Marine Grade Stainless Steel A4-70 G316 is the ultimate corrosion resistance fastener. Designed to be used in all conditions. It is the best material to use in marine, coastal, chemical and food environments. Stainless steels are largely non-magnetic, but it is not uncommon for some stainless steel fasteners to show a small degree of magnetism. This is partly due to the manufacturing process. Marine Grade Stainless Steel A4-70 G316 can be easily identified by the following markings: A4, A4-70, A4-80, 316 or G316. Small sized washers are generally not stamped
- 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
