M18 stainless steel ss316 round head hexagon decorative cap nut

Product Description

The cover nut, as the name implies, refers to a hexagon nut equipped with a protective cover. This cover serves to encase the outer part of the nut, guarding against moisture or corrosive elements to prevent rust formation. Ultimately, this helps to enhance the longevity and performance of the connector. Common standards for cover nuts in the fastening system include DIN1587, IFI standards, and GB/T923 brand parts standards.

Materials for cover nuts:

Our products primarily employ materials such as carbon steel (encompassing low, medium, high, and spring steel), stainless steel variants (SUS303, SUS304, SUS316), alloy steel, nylon, among others.

Surface treatments for cover nuts:

When utilizing cover nuts, surface treatment of the nut cover is essential. Techniques such as galvanization, nickel plating, chrome plating, and dacro coating are employed. These treatments enhance rust resistance, effectively extending the service life of fasteners. Among these methods, chrome plating stands out, offering a smooth, bright surface and prolonged resistance to rust and corrosion, rivalling the durability of stainless steel.

Type selection:

Our fastening system offers diverse recommendations for cover nuts based on customer-specific performance, material, and surface treatment requirements. We cater to varied preferences and needs in recommending suitable cover nuts.
