Primary Uses & Applications:
* High-end indoor furniture (kitchens, bathrooms, luxury cabinets).
* Outdoor & garden furniture (tables, chairs, benches, pergolas).
* Marine cabinetry & boat interior furniture.
* Bathroom vanities & fixtures.
* Furniture for humid climates or spas/saunas.
* Connecting hardware to exotic hardwoods or dense composites.
* Applications requiring a non-corroding, aesthetically clean fastener.
Surface Treatment/Finishes:
* **Passivation (Standard):** Essential chemical process that removes free iron particles and enhances the natural chromium oxide layer, maximizing corrosion resistance. Leaves a clean, slightly matte stainless finish.
* **Electroplated Nickel (Optional):** Provides a bright, silvery finish for enhanced aesthetics and *slightly* improved corrosion resistance. Can reduce galling tendency.
How to Use:
1. **Prevent Galling (Crucial):** Apply a small amount of **stainless steel specific anti-seize lubricant** or **wax** to the screw threads before installation. This drastically reduces the risk of galling (cold welding/seizing), especially in hardwoods or dense composites.
2. **Align Parts:** Position panels precisely.
3. **Insert & Drive:** Place screw tip on the surface. Insert the **correct size hex key**. Drive the screw at a **90° angle** using **steady, moderate speed and force**. The self-tapping point will cut threads.
4. **Tighten Flush:** Drive until the countersunk head is **fully seated flush** with the material surface. **Avoid excessive RPMs** which generate heat and increase galling risk.
5. **Pilot Holes:** Highly recommended for **hardwoods, near edges/ends, or thick/dense materials**. Drill a pilot hole slightly smaller than the screw's core diameter (approx. 60-70% of shank diameter). This prevents splitting and makes driving easier, reducing galling risk.
6. **Tool Quality:** Use high-quality, sharp hex keys or bits that fit snugly to avoid damaging the socket.
