Pan Head Thread-Forming Screw
Products Description
The Pan Head Thread-Forming Screw is a fastener specifically designed for connecting thin metal sheets. Its pan head structure provides a uniform bearing surface distribution, and the threaded section forms an internal thread within a pre-drilled hole through cold extrusion, rather than cutting away material. This design fundamentally eliminates the risk of metal debris contaminating precision electrical systems.
In the assembly of metal casings and internal structures in new energy storage systems, photovoltaic inverters, electric vehicle charging piles, and power electronic equipment, the Pan Head Screw's thread-forming mechanism ensures the integrity of the substrate's fibre structure, avoiding stress concentration and microcrack problems caused by traditional cutting threads. For industrial scenarios requiring long-term exposure to vibration, thermal cycling, and electromagnetic interference, this fastening solution achieves an engineering balance between connection reliability and system safety.
Technical Features and Advantages
Traditional self-tapping screws rely on "cutting + extrusion" to create threads, which easily generates chips (causing electronic short circuits) and substrate cracking (in thin-plate scenarios). This Pan Head Screw uses "cold extrusion forming," achieving a "metallurgical bond" between the thread and the substrate, increasing torsional strength by 50% and eliminating chip contamination.
The Pan Head Self-Tapping Screw's "large contact area + low height" avoids the "stress concentration" of countersunk heads in "limited space + high load" scenarios (such as inverter heatsink mounting), and is more compact than round heads, adapting to the "lightweight + high-density" layout of new energy equipment.
Product Application Advantages
Simplified Assembly Process
Eliminates the tapping process after drilling; the Pan Head Self-Tapping Screw directly enters the pre-drilled hole, increasing production line cycle time by over 30%.
Reduced Equipment Investment
The Pan Head Sheet Metal Screw eliminates the need for tapping machines or rivet guns, requiring only a standard electric screwdriver with torque control.
Adaptable to Automated Feeding
The pan head shape has been tested with a vibratory feeder, achieving a feeding success rate of ≥99.95% (including air-blown tracks), compatible with vacuum suction or magnetic pickup.
Cross-Project Versatility
The same Pan Head Wood Screw specification can cover connection points with different wall thicknesses and materials, reducing the workload of re-verification during engineering changes.
Product Details and Features
Precision Head Structure
The pan head of the Pan Head Phillips Screw is precision cold-forged to ensure consistent head dimensions, facilitating automated feeding and positioning.
Optimised Thread Profile
The thread geometry of the Pan Head Cross Recessed Screw is designed based on forming principles, ensuring locking capability while reducing assembly torque fluctuations.
Stable Drive Groove
Utilising a mature drive groove design, the risk of slippage during batch assembly is reduced. It meets the compatibility requirements of common assembly tools for the widely used Pan Head Phillips Screw in the international market.
