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.


TECHNICAL SPECIFICATIONS

Material A4-70 Stainless Steel (316)** (ISO 3506)
Drive Type  Phillips/Slotted Combination (PH2 Phillips + 3-4mm Slotted)
Head Style Cylindrical Head (Smooth lower shank, **Knurled upper grip section** - Fine groove knurl)

        *   M5 x 10mm, 12mm, 16mm, 20mm (Knurl Dia: ~7-8mm)
        *   M6 x 12mm, 16mm, 20mm, 25mm (Knurl Dia: ~9-10mm)

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.
