304 SS Furniture Screws Hex Drive Countersunk Self-Tapping Outdoor & Moisture Resistant

Premium A2-70 stainless steel hex socket furniture screws. No rust, ideal for outdoor, bathroom & kitchen furniture. Self-tapping tip, flush countersunk head. Passivated finish. M5-M8 sizes. Durable connections.

Build furniture to last, even in damp or outdoor environments, with our premium **A2 Stainless Steel Hex Socket Countersunk Self-Tapping Furniture Connecting Screws**. Crafted from corrosion-resistant A2-70 (304) stainless steel, these screws resist rust, tarnishing, and moisture damage, making them perfect for outdoor furniture, kitchens, bathrooms, marine interiors, and high-humidity areas. Featuring the same efficient **self-tapping point** and **flush-mounting countersunk head** as our standard screws, they combine ease of assembly with exceptional durability and a sleek appearance. The **hex socket drive** ensures reliable installation without stripping.

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.
