Custom M10 M18 Nylon Dome Cap Nuts M16 Acron nuts Black white round head Plastic Nuts

Cap nuts are used in the same way as hexagonal nuts. They are characterised by the fact that the main nut does not slide easily, but can only be tightened with a live spanner, a dull spanner, a dual-purpose spanner (open part) or a special square-hole socket spanner.

They are mainly used for rough and simple parts, in tyres and front and rear axles of cars, tricycles, electric cars, etc. They are also used for fixing the bases of road light frames and some mechanical equipments which are often exposed to sunlight and rain.

Machined Nylon (PA) Properties and Grades

Nylon (PA) is known for its high crystallinity, which produces strong, strain-resistant components. In addition, the use of nylon reduces the need for extensive lubrication, reduces noise and eliminates wear, corrosion and theft problems.

There are two common grades of nylon 6 and nylon 6/6 nylon that are noteworthy for their properties and uses. They can be used interchangeably in a variety of applications with some property differences.

• Nylon 6 is commonly produced in two forms: a high-strength type for textile applications and a high-strength type for industrial use.
• Nylon 6/6 has many industrial uses, from thin-walled parts to large, thick-walled bearings. It is also an excellent candidate for metal replacement.

• High mechanical strength, good toughness, and high tensile and compressive strength
• Smooth surface, low coefficient of friction, wear-resistant
• Corrosion resistant - very resistant to alkali and most salt solutions
• Self-extinguishing, odourless, non-toxic, weather-resistant

That is, the bolt, nut strength level is the same (bolt 8.8 and nut 8 strength level is the same, because the bolt after the '.8' that is the yield strength is 80% of the tensile strength.)

But consider the use of the situation if the nut is not easy to replace, the bolt is easier to replace, can also be changed to bolt 4.8 nut 5.
