304 Stainless Steel Phillips Pan Head Machine Screws A2-70 DIN 7985

304 SS Phillips Pan Head Machine Screws A2-70 Passivated Corrosion Resistant Custom Sizes

Premium A2-70 stainless steel Phillips pan head screws. Passivated finish resists rust, salt water & chemicals. M2 to M12 sizes. Custom options. Ideal for marine, food processing & outdoor. DIN 7985 compliant.

Demanding environments require superior corrosion protection. Our **A2 Stainless Steel Phillips Pan Head Machine Screws** deliver exceptional resistance to rust, salt water, chemicals, and atmospheric exposure. Made from A2-70 (304) stainless steel and featuring the standard **Phillips drive** and **DIN 7985 pan head profile**, they provide reliable fastening strength and a clean appearance for **marine, food processing, pharmaceutical, chemical, and outdoor applications**. *Screws only - no washers included.* Custom specifications available.

Primary Uses & Applications:

* Marine hardware & boat fittings.
* Food & beverage processing equipment.
* Pharmaceutical & laboratory equipment.
* Chemical plant fixtures & instrumentation.
* Outdoor enclosures & architectural metalwork.
* HVAC systems in corrosive environments.
* High-humidity appliance manufacturing.
* Potable water systems.
* Any application requiring non-corrosive, hygienic fasteners.

Surface Treatment/Finishes:
* **Passivation (Standard):** Critical chemical process removing free iron particles and enhancing the natural chromium oxide passive layer for maximum corrosion resistance. Slightly matte finish.
* **Electropolishing (Optional):** Creates a smoother, brighter, more reflective surface. Further enhances corrosion resistance, improves cleanability/decontamination (ideal for food/pharma), and reduces friction/galling tendency. Compliant with hygienic standards.

How to Use:

1. **Prevent Galling:** **Highly Recommended!** Apply a **stainless steel specific anti-seize compound** to the threads before installation, especially for stainless-on-stainless connections. This prevents thread cold welding (galling).
2. **Prepare:** Ensure female threads (nut/tapped hole) are clean, compatible, and ideally also stainless steel (A2/A4). Deburr holes.
3. **Insert:** Place screw through clearance hole.
4. **Drive:** Use the **correct size Phillips driver**. Apply **steady, moderate pressure and speed**. Avoid high RPMs which generate heat and increase galling risk.
5. **Tighten:** Tighten until snug and the pan head seats. **Do not over-torque.** Refer to A2 stainless torque specs.
6. **Washer Note:** For load distribution or vibration resistance, use **stainless steel flat washers or Belleville washers** (added separately).
7. **Removal:** Should be straightforward if anti-seize was used. If galling occurs, do not force - risk breaking the head
