Product Description
Nylon Insert Hex Flange Lock Nuts are a type of fastener designed to prevent loosening due to vibration or movement. These nuts feature a nylon insert that creates a prevailing torque, which helps maintain the tightness of the connection. They are commonly used in applications where reliability and stability are essential.
The nylon washer inside the nut compresses against the threads of the bolt, creating a secure grip that resists loosening over time. However, it's important to note that these nuts are not suitable for high-temperature environments or applications involving certain chemicals, as the nylon material can degrade under such conditions.
Available in various colors, nylon lock nuts are widely used across multiple industries including aerospace, automotive, medical equipment, appliances, and more. They are also known by several other names, such as nyloc nuts, nylock nuts, elastic lock nuts, and stop nuts.
These nuts are ideal for both regular and heavy-duty applications. While they can be reused a limited number of times, they should not be used with additional lock washers since the nylon insert already provides sufficient locking force.
Castellated nuts, a related type, are often used in low-torque situations like securing wheel bearings. They offer a positive locking mechanism through a split pin, R-clip, or safety wire once properly aligned.

Centrifugally Ductile Cast Iron Pipe is a kind of pipe made from spherical graphite cast iron by centrifugal spinning process. The pipes, which can convey many fluid media such as water, oil and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public service utility.
With its high strength, high elongation, corrosion resistance, resistance to shock, easy construction and many other fine features, ductile iron pipe is the best choice in today's world for conveying water and gas safely. Ductile iron, also called nodular iron or spheroidal graphite iron, is characterized by the presence of spheroidal graphite in the resultant castings.
Ductile iron pipes are available in a range of diameters from 80mm to 1600mm and are suitable for both potable water transmission and distribution (in accordance with BS EN 545) and sewerage (in accordance with BS EN 598).
Ductile iron pipes are simple to joint, can be laid in all weather conditions and often without the need for selected backfill. Its high safety factor and ability to accommodate ground movement make it the ideal pipeline material for a wide range of applications.
