Stainless Steel Pan Head Screws
Products Description
Stainless steel pan head screws are fasteners with a **pan head**. The head height is moderate, and the force distribution area is uniform, making them suitable for thin plate connections, visible assemblies, and structures requiring stable clamping.
Typical Structural Features
Pan Head Design: Large contact surface, uniform force distribution, reducing the risk of material indentation.
Phillips head/slotted head (customizable): Compatible with common power tools, high assembly efficiency.
Full or partial thread structure: Meets different connection depth and strength requirements.
Stainless steel body: Balances mechanical performance and environmental resistance.
This structural combination makes them stable in applications such as internal fixing of electrical appliances, connection of furniture components, and installation of building materials.
Scenario-based Adaptation Extension: Functional Upgrades Without Additional Costs
Appliance Appliance Adaptation
The pan head features an optional insulating coating (additional cost ≤10%), avoiding the risk of short circuits caused by the conductivity of stainless steel, and is compatible with internal connectors in home appliances; the stainless steel hex bolts shank length is precisely graded (6mm-50mm) to adapt to appliance shells and components of different thicknesses.
Furniture Adaptation
The pan head surface is sandblasted to increase friction with wood and boards, enhancing anti-loosening effects while preventing reflections from affecting the furniture's appearance; the thread pitch is optimized to coarse threads, reducing the risk of wood cracking and improving assembly efficiency.
Architectural Adaptation
A waterproof ring groove (optional) is added at the connection between the pan head and the shank, which can be used with a simple waterproof ring to prevent rainwater intrusion, suitable for slightly damp outdoor environments (such as balcony decoration and building ceilings), without the need to replace with high-end waterproof fasteners.
Technical Features
High-Speed Cold Forging Technology: This is the core technology for achieving large-scale, low-cost, and high-quality production. At room temperature, metal wire is extruded and deformed at high speed within a die, preserving the metal fiber flow lines and distributing them along the part's shape. Its strength and toughness far exceed those of machined parts.
Precision Thread Rolling Process: A flat thread rolling die is used to extrude and form threads on the stainless steel lag screws shank. This process produces threads with full tooth profiles, high surface finish, and higher hardness due to work hardening, ensuring smooth engagement with the nut and strong locking force.
Online Passivation Treatment: All stainless steel countersunk screws undergo continuous pickling and passivation treatment before leaving the factory. This chemical process effectively removes surface free iron and thickens the passivation film, maximizing its corrosion resistance potential.
Deep Integration with Industry Applications
| High-end Home Appliances & Consumer Electronics | From panel mounting in kitchen appliances to housing assembly in audio equipment, stainless steel hex head screws offer a clean appearance, resistance to fingerprints and kitchen grease, and durability against frequent wiping-key details for maintaining a product's "new" look. |
| Outdoor Furniture, Architectural Decoration, and Railing Systems | Exposed to sun and rain for extended periods. Our 316 stainless steel screws effectively resist rain, UV rays, and atmospheric pollutants, preventing rust stains on expensive wood or stone surfaces and ensuring the overall design remains pristine over time. |
| Food Processing and Medical Equipment | Needing to withstand high-temperature, high-pressure cleaning and repeated exposure to disinfectants (including chlorine). Our high-grade stainless steel coach bolts and electropolished surfaces meet stringent hygiene design requirements, including easy cleaning, residue-free operation, and chemical corrosion resistance. |
| Marine Interiors and Coastal Facilities | Salt spray corrosion is extremely severe in marine climates. Through a comprehensive solution of materials and surface treatments, our self tapping steel screws maintain their function and appearance for extended periods in harsh environments with high humidity and high salinity, making them a reliable choice for yachts, dock facilities, and coastal architecture. |
| Precision instruments and laboratory equipment | Their non-magnetic properties (especially 304/316 austenitic stainless steel) ensure they will not interfere with precision electromagnetic measurements. Furthermore, their stable dimensional accuracy and clean surfaces meet the requirements of precision assembly and cleanroom environments. |
