Product Description

The flat head knurled hand screw, a marvel of design and functionality, is a fastening component distinguished by its distinctive structure. Designed for effortless manual operation, its flat head, coupled with a knurled surface, ensures remarkable performance across a wide array of applications. Delve into the details below for a comprehensive understanding:

• Remarkable Appearance Features

Head design: Crafted with a flat screw head, this design boasts a top surface that lies flush with the installation plane. Unlike high-head screws, it offers a sleek, collision-free finish, ideal for installations where space is at a premium or where surface smoothness is paramount.

Knurling process: The head undergoes a precision rolling process, creating straight or mesh patterns that boost surface friction. This ensures a stable, tool-free manual operation, eliminating the need for screwdrivers and enhancing user convenience.

• Comprehensive Specification Parameters

Thread specifications: Available in common sizes such as M2, M3, M4, M5, M6, etc., where 'M' denotes metric threads, and the number indicates the nominal diameter. This variety caters to diverse fastening requirements with precision and reliability.

Length range: Our screws span from 3mm to 50mm in length. Shorter variants are ideal for thin plates, whereas longer screws cater to thicker or multi-layered components, providing versatile solutions for various installation needs.

• Premium Materials and Surface Treatment

Material type: Choose from robust materials like stainless steel, carbon steel, and brass. Stainless steel offers superior corrosion resistance for harsh environments. Carbon steel delivers high strength, enhanced through heat treatment, while brass excels in electrical and thermal conductivity, perfect for electronic applications.

Surface treatment: Enhance your screws with diverse surface treatments to boost rust resistance and durability. Galvanizing forms a protective layer against corrosion, nickel plating elevates aesthetic appeal and wear resistance, and blackening creates an oxide layer for both rust protection and decorative purposes.

• Diverse Application Scenarios

Electronic appliances: Perfect for securing components in devices like computers, TVs, and audio systems, these screws ensure easy installation, maintenance, and disassembly. They maintain a sleek and polished look, preserving the aesthetic integrity of the equipment.

Instrumentation: Widely used in assembling precision instruments, these screws protect the instrument's surface and guarantee the stable and reliable installation of internal components, thanks to their precise specifications.

Furniture assembly: Ideal for panel furniture and small wooden crafts, these screws facilitate easy, manual board connections. Post-installation, they provide a flat surface, enhancing aesthetic appeal without compromising on functionality.
