Product Description

The Flat Head Knurled Hand Screw stands out as an exceptional fastening component, ingeniously crafted for seamless hand operation. Its distinctive flat head shape, coupled with a functional knurled design, serves as an indispensable solution across diverse applications. Let us delve into a comprehensive examination of its features, benefits, and applications:

• Exquisite Appearance Features

Head Design: Engineered with precision, the screw head showcases a flat top surface, ensuring a broad contact area with the installation surface. Once installed, it remains flush, avoiding any protrusion as seen in high head screws. This design mitigates collision risks and excels in scenarios demanding space conservation or refined surface flatness.

Rolling Process: The head surface undergoes a rolling treatment, crafting either straight or mesh patterns. This amplifies surface friction, facilitating effortless and stable manual operations without the necessity for tools like screwdrivers, thus enhancing user convenience and efficiency.

• Detailed Specification Parameters

Thread Specifications: Available in a range including M2, M3, M4, M5, M6, etc., where 'M' signifies metric threads. Each number denotes the nominal diameter, offering versatile solutions for a spectrum of fastening scenarios.

Length Range: Spanning lengths from 3mm to 50mm, these screws cater to varied needs. Shorter screws are ideal for securing thin plates, while longer ones adeptly connect thicker or multi-layer components, accommodating a wide array of installation environments.

• Materials and Surface Enhancements

Material Type: Crafted from stainless steel, carbon steel, and brass. Stainless steel boasts corrosion resistance, suitable for humid, acidic, and alkaline settings. Carbon steel offers high strength, with performance enhancements via heat treatment. Brass shines with superior conductivity and thermal properties, making it perfect for the electrical and electronics sectors.

Surface Treatment: To augment rust prevention, wear resistance, and aesthetics, several treatments are applied. Galvanizing provides a protective layer, enhancing corrosion resistance. Nickel plating boosts aesthetics and durability. Blackening creates a protective oxide film with rust-resistant and decorative qualities.

• Versatile Application Scenarios

Electronic Appliances: Ideal for securing components in devices like computers, televisions, and audio systems, it seamlessly integrates into casings and circuit boards. This ensures easy installation, maintenance, and disassembly, while preserving an elegant and smooth exterior.

Instrumentation: A preferred choice in precision instrument assembly, these screws prevent surface damage and guarantee the stable installation of internal components, ensuring the instrument's reliability and performance.

Furniture Assembly: Widely utilized in panel furniture and intricate wooden crafts, it provides a quick, tool-free solution for board connections. Installed, it maintains flatness, preserving the overall aesthetic integrity of the furniture piece.
