Product Description

Our Flat Head Knurled Hand Screw is a remarkable fastening component, masterfully crafted to be operated directly by hand. Its uniquely structured flat head, combined with a faultlessly knurled design, ensures superior performance across a multitude of applications. Here's an in-depth exploration of its impressive features:

• Distinctive Appearance Features

Head Design: The screw features a superbly engineered flat head with an expansive top surface, ensuring an extensive contact area with the installation surface. Once installed, it remains flush without protruding like traditional high-head screws, minimizing collision risks. This is ideal for restricted spaces or when a sleek, flat surface is desired.

Rolling Process: The head's surface undergoes a meticulous rolling treatment, creating straight or mesh patterns to amplify surface friction. This enhancement guarantees easier, more stable manual operation, eliminating the need for auxiliary tools such as screwdrivers.

• Precision Specification Parameters

Thread Specifications: We offer a variety of standard metric thread specifications, including M2, M3, M4, M5, and M6. The 'M' denotes metric measurements while the number indicates the nominal diameter, allowing for versatile fastening solutions to meet diverse requirements.

Length Range: Our screws range from 3mm to 50mm in length. Shorter variants excel in fastening thin plates, whereas longer options are perfect for securing thick or multi-layered components, offering unmatched adaptability across varied installation needs.

• Superior Materials and Surface Treatment

Material Type: Crafted from top-notch materials such as stainless steel, carbon steel, and brass. Stainless steel is perfect for corrosive environments with moisture, acidity, and alkalinity. Carbon steel boasts high strength, further enhanced through heat treatment. Brass is prized for excellent conductivity and is a staple in electrical and electronic applications.

Surface Treatment: We employ advanced surface treatments to bolster rust resistance, enhance durability, and elevate other attributes. Galvanizing forms a protective barrier, improving corrosion resilience. Nickel plating enhances both aesthetic appeal and wear resistance. Blackening treatment creates an oxide film for dual rust protection and decorative allure.

• Diverse Application Scenarios

Electronic Appliances: Vital in securing components within devices like computers, TVs, and audio systems, ensuring ease in installation, maintenance, and disassembly. The screw maintains the equipment's smooth surface and aesthetic integrity.

Instrumentation: Indispensable in the precise assembly of diverse instruments, it safeguards the surface integrity while delivering precise specifications to ensure the stable, reliable installation of internal components.

Furniture Assembly: In panel furniture and intricate wooden crafts, these screws facilitate swift, easy manual connections of boards. Post-installation, they ensure a seamless, flat surface, preserving the overall elegance and design aesthetics.
