M4.2/M4.8 410 stainless steel cross countersunk head drill tail wire blue zinc flat head self-drilling screw dovetail nail dovetail wire for Construction & Woodworking

Our 410 stainless steel self-drilling dovetail screws are professional fasteners designed for construction, woodworking, and equipment installation scenarios. Made of high-quality 410 stainless steel, they feature excellent corrosion resistance and high tensile strength, effectively avoiding rust and deformation even in harsh indoor and outdoor environments.

 

The cross countersunk head design ensures a flush fit with the installation surface, preventing protrusions that could cause scratches or damage to other components. The self-drilling function eliminates the need for pre-drilling, greatly improving construction efficiency—simply align the screw with the target surface, and the sharp drill tail can easily penetrate wood, metal sheets, or plastic parts.

 

Available in M4.2 and M4.8 sizes, these dovetail screws are widely applicable to furniture assembly, equipment fixing, woodworking projects, and industrial installation. Each screw undergoes strict quality inspection to ensure precise thread accuracy and stable performance, making it suitable for both professional construction teams and DIY enthusiasts.

 

The blue zinc plating not only enhances corrosion resistance but also gives the product a neat and professional appearance. Whether used for bulk industrial installation or small-scale home improvement, these self-drilling dovetail screws balance practicality and durability, meeting the high-standard requirements of fastener use in various scenarios.
