Product DescriptionStainless Steel Pan Head Hollow RivetsStainless Steel Material: Corrosion Resistance & Mechanical DurabilityPan Head Structure: Load Distribution & Low-Profile VersatilityCross-Industry Applications: Tailored to Specialized NeedsStainless steel pan head hollow rivets are primarily crafted from high-performance grades, with 304 (A2) and 316 (A4) as the industry staples, delivering exceptional longevity and reliability across environments:Corrosion Resistance Hierarchy:304 stainless steel (18% Cr, 8% Ni) forms a chromium oxide passivation layer, achieving ≥200 hours of neutral salt spray resistance (ASTM B117)—suitable for indoor, dry, or mild outdoor settings (e.g., kitchen appliances, electronic enclosures).316 stainless steel (16% Cr, 10% Ni, 2-3% Mo) enhances resistance to saltwater, acids, and industrial fumes, with ≥500 hours of salt spray resistance—ideal for marine, coastal, or chemical processing applications (e.g., boat hardware, offshore equipment).Mechanical Performance:Compliant with ISO 3506-1:2020, 304-grade rivets offer a tensile strength of ≥515 MPa and shear strength of ≥210 MPa (for M5 size), while 316-grade variants reach ≥515 MPa tensile strength and ≥220 MPa shear strength. Both grades maintain ductility (elongation ≥40%) to avoid brittle fracture during installation.Surface Integrity:The natural smooth finish (Ra ≤0.8 μm) resists dirt accumulation, simplifying cleaning—critical for food-processing equipment or medical devices. Optional electrolytic polishing further s surface hardness to 300-350 HV, reducing wear from repeated handling.Adhering to ISO 15978:2002 (metric) and ANSI/ASME B18.1.1 (imperial), the pan head (semi-circular dome + flat supporting base) balances mechanical functionality and space efficiency:Stress Reduction on Thin Substrates:The wide head diameter (e.g., 6.0-7.8 mm for M4 rivets, 9.5-10.5 mm for M5 rivets) distributes clamping force over a 1.8× larger contact area than button-head rivets. For example, an M4×6 mm 304 stainless steel hollow rivet exerts ≤1.2 MPa pressure on a 1.0 mm-thick aluminum sheet—preventing material deformation, essential for fragile components like LED light housings.Low-Profile Protrusion:With a head height of 2.2-3.0 mm (M4) and 2.8-3.6 mm (M5), the design avoids interference with moving parts (e.g., sliding door rails, conveyor belts) while fitting into shallow recesses (e.g., 4 mm-deep electronics chassis).Aesthetic & Safety Advantages:The rounded dome eliminates sharp edges (reducing injury risks in consumer products) and complements visible assemblies (e.g., furniture, decorative panels). Unlike painted or plated rivets, stainless steel's natural luster retains appearance over time without chipping.Stainless steel pan head hollow rivets leverage their corrosion resistance, hygiene, and durability to serve diverse high-demand sectors:Marine & Coastal Engineering:316 stainless steel variants secure boat railings, dock hardware, and offshore platform components—withstanding saltwater corrosion and extreme temperature fluctuations (-40°C to 80°C).Food & Beverage Industry:304 stainless steel rivets assemble stainless steel tanks, conveyor systems, and food processors—meeting FDA 21 CFR 177.2600 standards for food contact, and resisting cleaning agents (e.g., sodium hypochlorite).Medical & Pharmaceutical Equipment:316L stainless steel (low-carbon variant) rivets are used in non-sterile device housings (e.g., diagnostic machines, hospital beds)—offering biocompatibility (ISO 10993) and resistance to disinfectants (e.g., ethanol, hydrogen peroxide).Electronics & Renewable Energy:304 stainless steel rivets mount solar panel frames, battery enclosures, and server racks—lightweight design reduces structural load, while corrosion resistance withstands outdoor or data center humidity.ItemDetailsStructural CompositionStainless Steel Pan Head Hollow RivetsstandardGB/T 876-1986Surface TreatmentStainless SteelPacking & DeliveryBag PackagingCarton PackagingFasteners can be packaged in durable plastic bags, which are available in various sizes to accommodate different quantities (e.g., small batches of screws, nuts, or bolts). The bags are typically sealed by heat or with a zipper to prevent moisture, dust, and loss of contents. This method is lightweight, cost-effective, and suitable for retail sales, small shipments, or situations where easy access to the fasteners is needed. Additionally, clear plastic bags allow for quick visual identification of the products inside.For larger quantities or bulk transportation, cartons are commonly used. These are sturdy cardboard boxes, often reinforced with corrugated layers to provide protection against impact during handling and shipping. Fasteners in cartons are usually pre-packed in bags or separated by dividers to avoid friction and damage. Cartons can be labeled with product details (e.g., type, size, quantity) and are stackable, optimizing storage and logistics efficiency. This method is ideal for industrial orders, wholesale distribution, or long-distance transportation where durability is a priority.Company ProfileCompany Name Hebei LING KE Metal Products Manufacturing Co.has firmly established itself as a leading force in the fastener industry, with a rich history and a commitment to excellence that spans over 10 years.
