Products Description
The Self-Drilling Thread-Forming Screw is a high-performance industrial fastener that integrates drilling, tapping, and fastening functions. It eliminates the need for pre-drilling, enabling quick and secure connections directly on substrates such as metal sheets, wood, and composite materials, significantly improving assembly efficiency and structural strength.
Key Selling Points
Integrated High-Efficiency Operation
The Self-Tapping Fastening Nail features an integrated drill bit and thread design, completing drilling, tapping, and fastening in a single operation, increasing installation efficiency by over 60% compared to traditional methods.
High Compatibility and Substrate Compatibility
Compatible with various substrates such as low-carbon steel, stainless steel, wood, and engineering plastics, meeting diverse connection needs.
Anti-loosening locking structure
The Self-Tapping Fastener's special thread profile design, combined with precision-machined thread lead, maintains stable locking force even under vibration conditions.
Weather-resistant and corrosion-resistant coating
The Self-Drilling Screw surface undergoes environmentally friendly nickel plating, achieving a salt spray test rating of 48-96 hours, demonstrating excellent durability even in high-humidity and highly corrosive outdoor environments.
Material Properties and Manufacturing Process
Material Properties: The Self-Tapping Thread-Forming Screw is cold-forged from high-carbon steel, achieving a hardness of HV350-450 after heat treatment, combining high strength and toughness. The stainless steel version uses 304/316 material, exhibiting excellent corrosion resistance in special applications such as food and medical.
Manufacturing Process: A precise process of cold forging + thread rolling + heat treatment + surface treatment is employed. The Auto-Tapping Screw's thread precision is controlled at 6H grade. The drill bit edge is precision-ground on a specialized grinding machine to ensure burr-free drilling and smooth tapping.
