Product Description

A black - plated slotted nut is a type of nut that combines the characteristics of slotted nuts with a black - plated surface treatment

Structure and Function

Materials and Standards

Applications

Slotted nuts, usually referring to hexagonal slotted nuts, have slots machined on the top of the hexagonal nut. They are used in conjunction with a bolt that has a hole in its shank and a split pin. The split pin is inserted through the slots of the nut and the hole in the bolt to prevent the nut from rotating relative to the bolt, thus playing a role in anti - loosening. The black - plating treatment can be black zinc - plating or black oxidation, etc. Black zinc - plating is an electroplating process that deposits a layer of zinc on the surface of the nut and then converts the zinc layer into a black dense oxide film through a specific chemical reaction. Black oxidation is a chemical oxidation process that forms a black oxide film on the surface of the nut through a specific chemical agent

They can be made of various materials such as carbon steel and stainless steel. Common material grades include Q235 carbon steel, etc. In terms of standards, they may comply with national or international standards such as GB/T 3098.2 or ISO standards

Due to their anti - loosening function and the protective and decorative properties of the black - plated surface, black - plated slotted nuts are widely used in mechanical manufacturing, automotive industry, and other fields. For example, they can be used to connect various mechanical parts such as bearings, gears, and couplings in mechanical manufacturing. In the automotive industry, they can be used to fix the front and rear wheel axles

Packing & Delivery

Bag Packaging

Carton Packaging

Fasteners can be packaged in durable plastic bags, which are available in various sizes to accommodate different quantities (e.g., small batches of screws, nuts, or bolts). The bags are typically sealed by heat or with a zipper to prevent moisture, dust, and loss of contents. This method is lightweight, cost-effective, and suitable for retail sales, small shipments, or situations where easy access to the fasteners is needed. Additionally, clear plastic bags allow for quick visual identification of the products inside.

For larger quantities or bulk transportation, cartons are commonly used. These are sturdy cardboard boxes, often reinforced with corrugated layers to provide protection against impact during handling and shipping. Fasteners in cartons are usually pre-packed in bags or separated by dividers to avoid friction and damage. Cartons can be labeled with product details (e.g., type, size, quantity) and are stackable, optimizing storage and logistics efficiency. This method is ideal for industrial orders, wholesale distribution, or long-distance transportation where durability is a priority.
