Product Description

Introducing the Flat Head Knurled Hand Screw: A uniquely engineered fastening marvel, designed for seamless manual operation. Its distinctive flat head combined with an intricately knurled structure offers unparalleled utility across diverse applications. Let's delve into its comprehensive features:

• Distinguished Appearance Features

Head Design: With a precisely flat top, this screw offers an expansive contact area with the installation surface, ensuring a seamless, flush finish. Unlike protruding high head screws, it minimizes collision risks and is perfect for tight spaces or when surface smoothness is a priority.

Rolling Process: Through expert rolling techniques, the screw head boasts straight or mesh patterns, enhancing surface grip. This design ensures effortless and stable hand tightening without auxiliary tools, such as screwdrivers.

• Versatile Specification Parameters

Thread Specifications: Available in a range of sizes, including M2, M3, M4, M5, M6. 'M' denotes metric threads, while the numeral specifies the nominal diameter, catering to diverse fastening requirements.

Length Range: Spanning from 3mm to 50mm, these screws adapt to various needs. Short lengths are ideal for securing thin materials, while longer options are suitable for thicker or multi-layered assemblies, ensuring versatile installation solutions.

• Premium Materials and Surface Excellence

Material Type: Crafted from premium materials like stainless steel, carbon steel, and brass. Stainless steel offers superb corrosion resistance for challenging environments; carbon steel provides exceptional strength, enhanced by heat treatment; brass delivers excellent electrical and thermal conductivity, ideal for electronic applications.

Surface Treatment: Diverse finishes enhance rust resistance, durability, and aesthetic appeal. Galvanization creates a protective layer for enhanced corrosion defense; nickel plating boosts visual appeal and wear resistance; blackening adds an anti-corrosive, decorative oxide film.

• Wide-ranging Application Scenarios

Electronic Appliances: Perfect for securing components in devices like computers, televisions, and audio systems. They ensure effortless installation, maintenance, and disassembly, maintaining a sleek, attractive surface appearance.

Instrumentation: These screws are integral to assembling precision instruments, safeguarding surfaces from damage and providing precise specifications for stable, reliable assembly of internal components.

Furniture Assembly: Ideal for connecting panels in furniture and small wooden crafts, enabling simple, swift manual operation. Ensures a flush finish post-installation, preserving the piece's aesthetic integrity.
