Technical parameters

Item	Details
Dual-Grade Stainless Steel Raw Material Selection	We provide two mainstream stainless steel grades: A2 (304) for general outdoor landscape projects and A4 (316) with extra molybdenum content for wet, humid, coastal courtyard drainage environments. All steel blanks undergo strict metallurgical composition testing to guarantee stable anti-rust performance and tensile strength for long-term outdoor exposure without rust spotting or fastener failure.
Global Multi-Standard Production & Flexible Custom Sizing	Manufacturing fully complies with DIN, GB, ANSI, BSW, JIS, GOST international fastener norms. There is no fixed standard size range; all diameters, shaft lengths and thread pitches can be tailor-produced strictly according to client engineering drawings. Every dimensional parameter is controlled under DIN/ISO precision tolerance standards to ensure smooth installation and interchangeability with s
Phillips & Slotted Combo Dual-Drive Structure	Integrated cross Phillips and straight slotted composite drive design enables assembly with both Phillips screwdrivers and flat-blade tools, greatly improving flexibility for site installation and later maintenance of drainage covers. Deep die-formed drive cavity effectively prevents tool slipping, slot deformation and torque loss during tightening, lowering on-site assembly defect rates compared
Smooth Round Pan Head Geometry	Rounded pan head sits neatly flush on drainage plate surfaces after tightening, avoiding sharp protruding edges that could scratch pedestrians or trap debris. Uniform head thickness and edge chamfer maintain stable stacking during packaging and prevent wobbling when pressed onto plastic, metal or wood drainage base substrates.
Sharp Self-Tapping Specialized Thread Profile	Precision rolled sharp self-tapping threads cut cleanly into plastic, thin metal and wooden drainage base panels without pre-drilling holes, speeding up courtyard drainage construction work. Dense, uniform thread teeth deliver strong locking clamping force, resisting loosening caused by rainwater impact, ground vibration and temperature fluctuation year-round.
Multi-Type Anti-Rust Surface Protection Treatments	Three practical finishing options match different project budgets and environment demands: passivation enhances the stainless steel's native corrosion resistance without altering part dimensions; high-gloss bright polishing delivers a neat aesthetic finish for visible drainage hardware; general anti-rust sealed finish offers cost-effective protection for mild inland outdoor conditions. All finishe
Reliable Cold Forging Core Manufacturing Workflow	Full production sequence includes blank cold forging for pan head forming, high-speed precision thread rolling, surface finishing treatment and full dimensional sorting inspection. In-process QC checks run through every production phase to unify batch consistency, suitable for both small sample trial orders and large bulk export shipments for landscape contractors.
Flexible OEM Customization & Fast Order Fulfilment	Drawing-based OEM & ODM service is fully supported for custom dimensions, surface finishes and branded packaging. Standard lead time spans 3-20 working days based on order quantity; complimentary pre-production samples are supplied for anti-corrosion and torque testing before mass order confirmation. Multiple global trade and payment terms are available to accommodate overseas buyers.
Sturdy Export-Grade Protective Packaging System	Inner waterproof polybags separate individual screws to shield polished and passivated surfaces from scratch abrasion during transit. Outer reinforced heavy-duty export cartons withstand stacking compression and shipping impact damage; extra bulk palletizing service is offered for large-volume orders to maximize container loading efficiency and cut international logistics expenses.
Targeted Outdoor & Drainage Application Scenarios	Primarily engineered for courtyard drainage cover locking, residential landscape water discharge system assembly, garden rainwater channel fixing, and coastal outdoor metal/plastic hardware mounting. Products are exported to Europe, Southeast Asia, North America and Australia, serving landscape engineering firms, drainage hardware wholesalers and outdoor construction contractors worldwide.
Core Product Competitive Advantages	Dual 304/316 stainless steel grade options, combo dual-tool compatible pan head self-tapping design, superior outdoor anti-corrosion performance, durable rolled self-tapping threads, multiple customizable surface finishes, over 15 years fastener manufacturing experience, direct factory competitive pricing, free test samples, flexible payment terms and dedicated after-sales technical support for cu
