Delve into an elaborate exploration of its attributes:

Distinctive Appearance Features

• Elevated Head Design: Sporting a high head design, our screws surpass ordinary counterparts with a taller, larger head that offers an expansive contact area, ensuring ease in manual manipulation. This design shines in constricted spaces, providing an optimal grip for applying finger force.

• Enhancing Grip with Rolling Patterns: The screw head is adorned with various rolling patterns such as straight or mesh lines, augmenting surface roughness. This crucial feature boosts friction and mitigates slippage, transforming screw turning into a smooth, stable endeavor, elevating operational convenience.

Comprehensive Specification Parameters

Thread Specifications: A broad spectrum of specifications awaits selection, including M3, M4, M5, M6, M8, M10, M12, and others. Here, 'M' denotes metric threads, and the accompanying numeral signifies the thread's nominal diameter.

• Versatile Length Range: Our screws come in a plethora of length dimensions, generally spanning 5mm to 100mm. This range empowers users to choose specific lengths tailored to their actual application needs.

• Additional Parameters: Beyond thread specifications and length, other crucial parameters define our high head knurled hand screws, encompassing head diameter, thickness, and thread length. These parameters adapt to diverse specifications and application scenarios, ensuring versatility.

Premium Materials and Surface Treatment

• High-Quality Materials: We offer a selection of materials including iron, carbon steel, stainless steel, copper, aluminum, titanium, etc. Each material brings unique performance attributes; for instance, stainless steel excels in corrosion resistance for harsh environments, while copper's excellent conductivity and thermal properties suit electrical equipment.

Surface Treatment Excellence: To enhance screws' longevity and performance, we employ various surface treatments like blackening, galvanizing, phosphating, and electrophoresis. Blackening produces an aesthetic black oxide layer, boosting rust resistance, while galvanizing adds a zinc layer for superior corrosion and wear resistance.

Adherence to Standards and Specifications

Execution Standard: Our high head knurled hand screws are manufactured and inspected in alignment with the national standard GB/T 834. This standard delineates size, technical requirements, testing methods, and additional specifications, assuring quality.

Comprehensive Marking Method: In accordance with national standards, our screw markings encompass thread specification, nominal length, performance grade, surface treatment, as evidenced by labeling such as GB/T 834 M5 × 20-8.8-Zn, detailing a screw with M5 thread, 20mm length, 8.8 performance grade, and galvanized surface.

Versatile Application Area

Electronic Devices: These high head knurled hand screws excel in securing components in electronic devices like computer cases, mobile phones, tablets, etc. They facilitate easy installation and disassembly while safeguarding electronic components during operation, making them indispensable in tech assemblies.
