The non-ferrous metals industry includes geological exploration, mining, mineral processing, smelting and processing. The content of non-ferrous metals in ores is generally low. In order to obtain 1 ton of non-ferrous metals, it is often necessary to mine ore of hundreds of tons or more. Therefore, the mine is an important foundation for the development of the non-ferrous metal industry. Non-ferrous metal ores are often symbiotic with a variety of metals, so it is necessary to rationally extract and recover useful components for comprehensive utilization in order to make rational use of natural resources.

Many kinds of chemical products such as rare metals, precious metals and sulfuric acid are recovered in the process of processing non-ferrous metal ores or intermediate products, as well as slag and soot. In the production process of non-ferrous metals, a large amount of waste gas, waste water and waste residue are usually produced, which contain various useful components, sometimes containing toxic substances, and some non-ferrous metals are also toxic. Therefore, in the process of producing non-ferrous metals, attention must be paid to comprehensive utilization and environmental protection.

Wing Screws

Wing Bolts, or Wing Screws, featured elongated `wings` that are designed to be easily operated by hand and are created to DIN 316 standard.
They can be used with Wing Nuts to create an exceptional fastening that can be adjusted from various positions.

Wing Bolts host lengths is customized, with varying wing widths also available.

Wing screws are a type of fastener that have a wing-shaped head for easy manual tightening and loosening. They typically have a threaded body and are used to secure objects together or to provide a means of adjustment. The wings on the head of the screw allow for quick and convenient hand turning, eliminating the need for tools such as screwdrivers or wrenches. Wing screws are commonly used in applications where frequent adjustments or removals are required, such as in furniture assembly, machinery, or DIY projects.


Wing screws are a type of fastener that have a large, flat, and often wing-shaped head. They are designed to be tightened or loosened by hand, without the need for tools. Here are some ways to describe wing screws:

1. Wing screws are threaded fasteners with a wide, flat head that resembles a wing.
2. These screws have a unique design, featuring a broad, wing-like head for easy manual tightening.
3. Wing screws are easily identifiable due to their distinctive head, which has two extended wings on either side.
4. These screws are specifically designed for quick and convenient hand tightening or loosening, eliminating the need for tools.
5. Wing screws have a large, flat head that provides ample surface area for a comfortable grip during manual operation.
6. These fasteners feature a head with extended wings, allowing for easy and secure handling, even in tight spaces.
7. Wing screws are commonly used in applications that require frequent adjustments or where tool-free installation is desired.
8. The wing-shaped head of these screws provides enhanced leverage, making them easy to tighten or loosen by hand.
9. Wing screws are often made of durable materials such as stainless steel or brass, ensuring long-lasting performance.
10. These screws are commonly used in various industries, including furniture assembly, automotive, and electronics, due to their ease of use and versatility.
