Stainless Steel Carbon Steel Pan Head Self-Drilling Screws Cross-head Cap Screws

This series of cross-head drive screws are an all-in-one fastening solution specifically designed for metal plate connection scenarios. They integrate the functions of drilling, tapping, and locking, eliminating the need for pre-drilling. They can directly penetrate metal substrates such as steel plates, color steel sheets, and aluminum profiles to complete fixation. The product covers three main versions: 304 stainless steel model, carbon steel blackened model, and carbon steel galvanized model, which are respectively suitable for different requirements such as regular working conditions, damp corrosion resistance, and appearance compatibility. The cross-head design of the screws combines ease of installation with the flatness of the workpiece surface, making them efficient and universal fasteners for steel structures, sheet metal assembly, and roofing projects.

Core structure: Standard cross-head design, equipped with hardened drill tail tip, full-thread self-tapping, integrating functions of drilling, tapping, and locking.

Material and coating: 1. 304 stainless steel model: No coating, original corrosion resistance, excellent salt spray resistance; 2. Carbon steel blackening model: High-temperature blackening treatment, matte and wear-resistant anti-rust, suitable for non-exposed scenarios; 3. Carbon steel galvanized model: Blue-white zinc passivation, bright and anti-rust, outstanding cost-effectiveness.

Specification coverage: Complete thread specifications of M4.2, M4.8, M5.5, M6.3, selectable length from 13 to 100mm, supports non-standard customization.

Performance: The drill tail is hardened and not prone to breakage, the thread bites tightly and is anti-loosening, different models respectively meet the requirements of anti-corrosion, wear resistance, and rust prevention, suitable for various metal plates.

Installation compatibility: No pre-drilled holes required for installation, compatible with conventional cross screwdrivers / electric drills, single person operation, suitable for steel structure construction and automated assembly.

Installation without pre-drilling, complete process in one step

Equipped with hardened drill tail tip, with high hardness and low cutting resistance, it can directly penetrate metal sheets without the need for pre-drilling and tapping. One-step installation is completed, with an efficiency increase of over 60% compared to traditional screws. It is particularly suitable for batch steel structure construction scenarios.

Three material options, precise adaptation for all working conditions

The stainless steel model is naturally resistant to salt fog and corrosion, suitable for coastal and outdoor humid environments; the blackening model is wear-resistant and rust-proof, with a matte finish suitable for non-exposed equipment internal scenarios; the galvanized model offers high cost-effectiveness and excellent rust prevention performance, making it the preferred choice for regular indoor and outdoor conditions. No additional customization is required to cover different needs.

Hardened drill tail + precise threads, stable and anti-loosening connection

The drill tail tip is specially hardened, not prone to breaking or wearing, suitable for high-strength sheets; the threads adopt CNC rolling process, with regular tooth shape and tight engagement, and are not prone to slipping or loosening after tightening, maintaining stable locking force even under long-term wind vibration conditions.

Disc head cross design, convenient installation without damaging the workpiece

The circular disc head has a large contact surface, making it less likely to damage the sheet surface during tightening; the cross groove is compatible with regular screwdrivers / electric screwdrivers, with uniform torque transmission, not prone to slipping or splintering, and can be quickly completed by one person, suitable for automated assembly lines.

Integrated molding process, strong and durable

The screw body is made by cold forging integration, without welding or splicing, the rod body has uniform and stable strength, with compliance standards for tensile and shear strength, and is not prone to breaking or deforming over a long period of use, ensuring the safety of steel structure connections.
