How We Match Capacity, Price, and Service to Your Market
- Capacity fits your selling season. We plan production around your peak months and repeat sizes, so lead times hold when your market demand picks up-not just on the first order.
- Price fits your shelf. Integrated screw and EPDM washer production keeps unit cost at a level that supports your target wholesale price and margin, without downgrading the washer or coating.
- Service fits your market requirements. We adjust packing, labels, sizes, and washer specs to your local roofing practice and climate-so the product lands ready to sell, not needing rework.
- Proof before price. Free samples before mass production let you confirm the product matches your market plan-then we talk price on a product you know fits.
- In short: we don't quote our factory's strengths in general-we align capacity, cost, and service with the market you sell into.
Head & Point Features
CSK (Countersunk) Head: The flat 90° countersunk head sits flush with the material surface, providing a smooth, clean finish ideal for applications where protrusions are undesirable.
Self-Drilling Point: Our self-drilling screws eliminate the need for pre-drilling, reducing installation steps by up to 50%. The integrated drill point cuts through metal quickly and cleanly, allowing workers to complete projects faster with fewer tools. This directly translates to lower labor costs and increased project efficiency.
Material & Anti-Corrosion
Available in SS304 for general-purpose corrosion resistance, suitable for indoor and mild outdoor environments.
SS410 offers enhanced hardness and wear resistance, ideal for structural applications requiring higher strength.
Crafted from premium SS304 or SS410 stainless steel, our screws provide superior rust and corrosion resistance. Whether exposed to moisture, coastal air, or industrial chemicals, these fasteners maintain structural integrity and appearance over time-reducing costly callbacks, replacements, and safety risks.
