Product Description

Experience the innovative design of the High Head Knurled Hand Screw, a staple in mechanical components. Its elevated head shape paired with intricately knurled patterns offers effortless manual tightening and loosening, eliminating the need for additional tools.
Delve into a comprehensive insight into its remarkable features:

Distinctive Appearance Features

• Head Shape: Embrace the high head design, which stands taller and larger than typical screws, providing a more extensive contact area for seamless manual handling. Its elevated design is particularly beneficial in confined spaces, making finger application efficient and straightforward.

• Knurled Surface Pattern: The screw's head is adorned with distinct rolling patterns, including straight and mesh lines. These patterns enhance surface roughness to boost friction, which eases turning and significantly reduces slippage, augmenting both convenience and operational stability.

Precise Specification Parameters

Thread Options: Choose from a versatile range of specifications such as M3, M4, M5, M6, M8, M10, M12, where 'M' denotes metric threads and the succeeding number reflects the nominal thread diameter.

• Varied Length Range: Length options are diverse, spanning from 5mm to 100mm, allowing you to select the exact length tailored to meet your specific application requirements.

• Additional Parameters: Beyond threads and lengths, consider other critical dimensions such as head diameter, thickness, and thread length, all of which may differ depending on the screw's specifications and intended applications.

Superior Materials and Advanced Surface Treatment

• Material Selection: Choose from a range including iron, carbon steel, stainless steel, copper, aluminum, or titanium. Each material boasts unique performance traits; stainless steel offers excellent corrosion resistance for harsh environments, while copper's superior conductivity makes it ideal for electrical uses.

Sophisticated Surface Treatment: Enhance screw performance and longevity through surface treatments like blackening, galvanizing, phosphating, or electrophoresis. Blackening imparts both aesthetic appeal and rust resistance, while galvanizing adds a protective zinc layer, boosting corrosion and wear resistance.

Compliance with Standards and Specifications

Adherence to Standards: Manufactured and inspected under the national standard GB/T 834, these screws meet rigorous requirements for size, technical specs, and testing methods, ensuring top-notch quality.

Exact Marking Protocol: As per national standards, screws are marked with thread specifications, nominal lengths, performance grades, and surface treatments, e.g., GB/T 834 M5 × 20-8.8-Zn, indicating an M5 thread, 20mm nominal length, performance grade 8.8, with galvanizing treatment.

Versatile Application Areas

Electronics Compatibility: In electronics like computer cases, mobile phones, and tablets, high head knurled hand screws secure components like casings, hard drives, and memory modules. They offer easy installation, removal, and prevent damage during operation, making them indispensable in the tech industry.
