OEM N19 Staples Technical Specifications & Engineering

Constructed from premium carbon steel wire or anti-corrosive stainless steel, our N19 staples offer unparalleled pull-out resistance and tensile resilience for tough structural connections.

16-Gauge Heavy Wire Profile

Engineered with 16-gauge (1.6mm diameter) high-tensile wire, the N19 staple offers superior shear resistance compared to standard narrow-crown staples, preventing wood splitting while securing structural sheathing.

7/16-Inch Intermediate Crown

The 7/16-inch (11.1mm) crown width provides optimized clamping distribution across OSB, plywood sheathing, and dense packaging crates. It ensures tight clamping without fracturing the base material.

Custom Coated & Chisel Points

Engineered with polymer-coated legs to facilitate ease of drive and boost withdrawal values. Sharp chisel points guarantee clean penetration through tough structural lumbers without buckling.

Application Scenarios

Global Commercial Applications of N19 Staples

From high-frequency automated packaging lines in Germany to coastal framing projects in North America, N19 staples deliver reliable holding power.

Structural Framing & Sheathing

Widely utilized across the United States, Canada, and Scandinavia for fastening Oriented Strand Board (OSB) and plywood sheathing to wall and roof frames. High shear load ratings secure homes against seismic movements and high winds.

Heavy-Duty Wooden Crates & Pallets

Logistics hubs and export companies in China and Europe trust N19 staples to construct durable wooden pallets and shipping crates. The polymer coating ensures resistance to pull-out forces during transport vibration.

Subflooring and Decking Underlayment

Eliminates the floor squeaking commonly caused by nail loosening. N19 staples clamp tightly through underlayment materials, and their low profile ensures a flat surface for carpet or hardwood overlays.

Automated Prefab Assembly Lines

Optimized for automatic pneumatic stapling machines used in manufactured home facilities. The precise alignment and glue collation eliminate jam rates, allowing continuous assembly line runtime.

In-House Control System

Precision Taiwanese & German Engineered Lines

At SINSUN, our quality control begins at the source. We start with premium raw materials from XING TAI Steel, then perform in-house spheroidizing annealing and precision wire drawing in our own plant. This end-to-end control, supported by our advanced drawing machines and gas-fired furnaces, ensures superior microstructure, consistency, and performance in every fastener we produce.

We combine German-engineered multi-station cold heading machines with precision Taiwanese production technology. Our specialized processes, including tail-gripping for drill screws and high-precision tooling for staples, ensure every fastener is manufactured with utmost accuracy and consistency.

Our production prowess is driven by German-imported machinery, precision Taiwanese technology, and a dependable staff of trained specialists. We offer over 20,000 SKUs of nails, screws, wires, and rivets, each undergoing 12+ stringent quality checks to assure outstanding polish (Ra ≤ 0.4μm), corrosion resistance (1,000+ hours salt spray), dimensional accuracy (±0.02mm), high strength (1,000+ MPa), and consistent hardness (HRC 28-32).

Annealing & Drawing

Ensuring the perfect wire temper, hardness, and mechanical ductility before collation.

Multi-Station Forming

Precisely bending the crowns and shaping chisel-sharp points for optimized penetration.

Advanced Collation Glue Treatment

Our proprietary formulation guarantees strong bonding of the staples strip, preventing breakage during transportation or high-vibration pneumatic tool operations.

Technical FAQ

Frequently Asked Questions: OEM N19 Staples Procurement

Answers to common structural specifications, bulk packing requirements, and lead times from our technical support department.

1. What are the key dimensional differences of N19 staples compared to other heavy wire staples?
N19 staples feature a standard 16-gauge wire diameter (approx. 1.6mm) and a 7/16-inch (11.1mm) crown. Other models, such as the N17, feature wider crowns (often up to 1/2-inch or 16-gauge variants of differing lengths). The N19 design is optimized for sheathing and decking applications, striking an ideal balance between crown width and shear capacity.
2. How does Sinsun Hardware ensure the collation wire glue does not break inside pneumatic tool magazines?
We use premium polymer collation glues and custom drying ovens to ensure our staples remain aligned. This prevents the strips from shattering during transport or when subjected to the high-impact recoil of pneumatic staplers, minimizing downtime on the field.
3. What raw materials are available for OEM customization of N19 staples?
We offer carbon steel wires (Q195, Q235) with varying degrees of zinc coating, as well as Grade 304 and 316 Stainless Steel for coastal construction, chemically treated lumber, and cleanroom packaging applications.
4. What is the MOQ (Minimum Order Quantity) for OEM branded packaging?
For custom packaging designs, our standard MOQ is 1 FCL (Full Container Load) per specification. This allows us to optimize manufacturing configurations and provide the best pricing. For standard stock sizes, lower minimums can be coordinated through our export managers.
5. Do you offer salt spray test verification report for anti-corrosion properties?
Yes, our QA lab performs testing up to 1000+ hours in salt spray chambers. We provide full mill test certificates (MTC) and corrosion compliance reports according to ASTM standards for every production batch.
