Product Description

Black - plated knurled high nuts are a type of fastener that combines functionality, aesthetics, and durability. They play a crucial role in various industries and applications, offering unique features that set them apart from regular nuts.

Purpose of Black - Plating

Standards

Applications

The black - plating on these nuts serves multiple purposes. Firstly, it offers enhanced corrosion resistance. The black - plating layer acts as a protective barrier against moisture, chemicals, and other environmental factors that could potentially cause rust or degradation of the base metal. This is especially important in outdoor applications or in industrial settings where the nuts may be exposed to harsh conditions. Secondly, the black color gives the nuts an aesthetically pleasing appearance. The sleek black finish can add a touch of modernity and sophistication to the overall design of the product or structure where they are used. It can blend well with various color schemes, whether in a contemporary industrial design or in a more high - end consumer product.

Black - plated knurled high nuts are typically manufactured to meet certain industry standards. In China, GB/T 806 - 1988 specifies the requirements for knurled high nuts, covering aspects such as dimensions, material properties, and manufacturing tolerances. In the international market, standards like DIN 466 in Germany define the characteristics of high - type knurled nuts. Adhering to these standards ensures that the nuts are of consistent quality, have proper dimensions for interchangeability, and possess the required mechanical properties for their intended applications.

Automotive Industry
In the automotive industry, black - plated knurled high nuts are used in various parts. They can be found in the interior for fastening components such as dashboard trims, seat adjustments, and center console parts. The knurled surface allows for easy manual adjustment by the user, and the black - plating not only provides corrosion resistance in the vehicle's interior environment but also matches the overall aesthetic of modern car interiors. In the engine compartment, they may be used for securing small components or for making adjustments to certain engine parts during maintenance or tuning.

Packing & Delivery

 Plastic Bags

Carton Boxes

Each unit or small batch of black-plated knurled high nuts is first sealed in thin, flexible polyethylene (PE) bags. These bags, typically 0.03–0.05 mm thick, are designed to prevent friction between nuts, which could scratch the delicate black plating or wear down the knurled patterns. For example:

Small  (M3–M6): 10–50 pieces per bag, with the bag size ranging from 5 cm × 8 cm to 8 cm × 12 cm (adjusted to fit snugly and minimize movement).
Larger  (M8–M10): 5–20 pieces per bag, in bags sized 10 cm × 15 cm to 12 cm × 20 cm.

Sealed plastic bags of black-plated knurled high nuts are packed into sturdy double-walled corrugated cartons. These cartons have a bursting strength of 250–300 psi to resist impacts. Common dimensions depend on the nut size and quantity:

For M3–M6 nuts (1000 pieces total): Cartons measuring 20 cm × 15 cm × 10 cm.
For M8–M10 nuts (500 pieces total): Cartons sized 30 cm × 20 cm × 15 cm.

To prevent shifting, cartons are filled with foam inserts or crumpled paper, creating a secure fit that absorbs shocks during transportation.
