1. Screw Product Names (Standard Chinese Expressions)
- 304 Stainless Steel: 304 Stainless Steel (a material category, commonly used to indicate the material property of screws)
- 8.8 Grade Hardened Cup Head Hexagon Socket Self-Tapping Screw: 8.8 Grade Hardened Cup Head Hexagon Socket Self-Tapping Screw ("Cup Head" is equivalent to "Cylindrical Head", which is a common abbreviation in the industry; the full expression can be "8.8 Grade Hardened Cylindrical Head Hexagon Socket Self-Tapping Screw")
- Stainless steel screw: Stainless steel screw (a general term for screws made of various stainless steel materials)
- Cylindrical Head Hexagon Socket Self-Tapping Nail: Cylindrical Head Hexagon Socket Self-Tapping Nail ("Nail" and "Screw" are often interchangeable in the industry; here it specifically refers to self-tapping fasteners with a cylindrical head and a hexagon socket)
- Audio Screw: Audio Screw (a scenario-specific screw, specifically referring to special screws suitable for assembling audio equipment, with a focus on surface flatness and connection stability)
-
Hexagon Socket Cylindrical Head Self-Tapping Locking Screw: Hexagon Socket Cylindrical Head Self-Tapping Locking Screw ("Screw" is a standard fastener term, consistent in meaning with "bolt"; this expression places more emphasis on the locking function of the product)
2. Product Characteristics of Hexagon Socket Cylindrical Head Self-Tapping Locking Screws
The hexagon socket cylindrical head self-tapping locking screw is a special type of hexagon socket screw. Its structural features are as follows: the head adopts a hexagon socket cylindrical head design, the tail is in a sharp shape, and it has a self-tapping function.
During use, there is no need to pre-drill holes or tap threads on the connected parts (such as wood, plastic, thin metal plates, etc.). Relying on the self-tapping property of the sharp tail, it can directly cut into the material and form threads through rotation, realizing rapid positioning and firm locking of components. At the same time, the hexagon socket design of the head facilitates operation with a hexagon socket wrench, allowing precise application of tightening torque. Compared with ordinary slotted or cross-slot screws, it is less likely to have the problem of "wrench slippage" (slot damage caused by wrench slipping), making it especially suitable for scenarios with narrow installation space and high requirements for connection strength.
3. Specifications of In-Stock Materials of Our Company
Our company currently supplies the following screw materials and surface treatment processes in stock, with sufficient inventory to meet customers' urgent procurement needs:
- SUS304 Stainless Steel: Made of SUS304 stainless steel, it has excellent corrosion resistance, which can resist the erosion of humid environments and weak acid-alkali media, and is suitable for various indoor and outdoor scenarios (such as outdoor lighting brackets, audio equipment used in humid environments, etc.). At the same time, it has stable mechanical properties and is not easy to break or deform during installation and long-term use.
- 8.8 Grade Black Oxide Coated & Galvanized: The material strength grade is 8.8 (a high-strength grade that can withstand large tensile force and shear force). The surface adopts black oxide coating (improving rust resistance, with a black appearance, suitable for scenarios where there are no high requirements for appearance but rust resistance is needed) and galvanized coating (enhancing rust resistance through a zinc layer, with a silver-white appearance, suitable for various indoor and outdoor scenarios) respectively.
For detailed specifications of specific products (such as screw diameter, length, thread pitch, head height, etc.), quotations and delivery cycles, please feel free to consult us at any time.
4. Main Application Industries
The products are mainly applied in the lighting industry and audio industry, with specific application scenarios including:
- Lighting Industry: Used for the assembly of various lamps, such as fixing lamp housings, lamp holders, light source modules and other components. Among them, screws made of SUS304 stainless steel are suitable for outdoor equipment such as street lamps and garden lights, which can resist rust caused by wind and rain; 8.8 grade high-strength screws are suitable for large indoor chandeliers, stage spotlights and other lamps with high requirements for load-bearing and connection stability.
- Audio Industry: As special audio screws, they are used to fasten audio casings, speaker units, internal circuit boards and brackets and other components. Their cylindrical head hexagon socket design can prevent the head from protruding and affecting the flatness of the audio appearance, and the self-tapping function simplifies the assembly process of the audio casing (usually made of aluminum alloy or plastic), improving production efficiency.
