Knurled Captive Screws A2 Combo Phillips/Slotted Server Rack & Enclosure
Premium A4-70 knurled captive screws for corrosive/clean environments. Combo drive, captive design. Passivated or electropolished. For medical devices, lab & food processing equipment. Hygienic.
Meet the demanding hygiene and corrosion resistance requirements of medical, laboratory, and food processing equipment with our **A4 Stainless Steel Knurled Captive Screws**. Crafted from A4-70 (316) stainless steel, they offer **superior resistance** to salt water, chemicals, acids, and frequent cleaning agents. The **partially knurled cylindrical head** enables easy, frequent access, while the **smooth lower section** minimizes crevices for easy cleaning. The **Phillips/Slotted combo drive** ensures secure installation. The **captive washer system** prevents screw loss, critical in sterile environments. Available passivated or electropolished for maximum smoothness and cleanability.

Primary Uses & Applications:
* Medical device housings & access panels.
* Laboratory equipment & analyzers.
* Pharmaceutical processing & packaging machinery.
* Food & beverage processing equipment.
* Biotech & cleanroom instrumentation.
* Marine scientific equipment.
* Chemical handling systems.
* Any application requiring frequent access, high corrosion resistance, and easy cleaning/sanitization.
Surface Treatment/Finishes:
* **Passivation (Standard):** Mandatory for corrosion resistance. Removes free iron.
* **Electropolishing (Highly Recommended):** Significantly smoothes surfaces (Ra < 0.4 µm), removes micro-imperfections, enhances corrosion resistance, improves cleanability, reduces bacterial adhesion, and provides a bright, easy-to-inspect finish. Compliant with FDA, USDA, 3-A Sanitary Standards for hygienic applications.
How to Use:
1. **Panel Prep:** Install **A4 stainless steel captive receptacles** (threaded inserts/standoffs) into the frame. Ensure material compatibility.
2. **Insert Assembly:** Insert the captive screw assembly through the panel hole.
3. **Installation (Tool):** Use a **clean PH2 or slotted driver** to tighten the screw securely. Achieve metal-to-metal contact for grounding if needed. *Follow sanitized handling procedures.*
4. **Tool-Less Access:** For routine access, **hand-tighten/loosen using the knurled grip**. The captive design prevents screws from falling into sensitive areas.
5. **Cleaning:** The smooth surfaces (especially electropolished) and minimized crevices allow for effective cleaning, wiping, spraying, or autoclaving (check EP specs). No threads are exposed when tightened.
6. **Inspection:** The bright EP finish allows easy visual inspection for damage or contamination.
