Introducing the high head knurled hand screw, a staple in the realm of mechanical components. Designed with an elevated head and imbued with intricate knurled patterns, this screw offers the convenience of manual adjustment, eliminating the need for any tools. Simply tighten or loosen by hand with effortless ease.
Below, we delve into the specifics of its features and advantages:
Exquisite Appearance Features
• Head Shape: The distinctive high head design sets it apart, boasting a larger head than conventional screws. This results in an expansive contact area, facilitating swift manual operations—even in confined spaces where finger pressure is paramount.
• Knurled Surface: The screw head's textured patterns, whether straight-lined or mesh-like, enhance surface roughness. This increase in friction ensures a firm grip, preventing any slippage during tightening, thus boosting operational ease and durability.
Comprehensive Specification Parameters
Thread Specifications: A versatile range of metric threads, including M3, M4, M5, M6, M8, M10, M12, offers adaptability. 'M' signifies metric, and the number denotes the thread's nominal diameter.
• Length Range: Spanning from 5mm to 100mm, the diverse length options cater to varied practical requirements, ensuring a perfect fit for every project.
• Additional Parameters: Beyond threads and length, other attributes like head diameter, thickness, and thread length are customizable. These parameters vary to suit specific specifications and diverse application environments.
Premium Materials and Surface Treatment
• Materials: From iron and carbon steel to stainless steel, copper, aluminum, and titanium, the material choice influences performance. Stainless steel excels in corrosion resistance for harsh settings, while copper is prized for its exceptional conductivity in electrical equipment.
Surface Treatment: Elevate performance and longevity with sophisticated surface treatments such as blackening, galvanizing, phosphating, and electrophoresis. Blackening forms a protective oxide layer, enhancing allure and rust resistance. Galvanizing adds a zinc layer, boosting resistance to corrosion and wear.
Rigid Standards and Specifications
Execution Standard: Production and inspection of high head knurled hand screws adhere to the GB/T 834 national standard, ensuring precise dimensions, technical criteria, testing protocols, and more.
Marking Method: In line with national standards, screw markings detail thread specification, nominal length, performance grade, and surface treatment. A typical mark, such as GB/T 834 M5 × 20-8.8-Zn, conveys these specifications concisely.
Diverse Application Areas
Electronic Devices: Ideal for securing components in electronic devices like computer cases, mobile phones, and tablets, these screws ensure easy installation and removal. They provide a secure hold without compromising delicate electronics during use.
