Accessoires d'installation Cleanroom
Acier inoxydable auto-tapping vis
A corrosion-resistant hex washer-head self-drilling screw for fixing cleanroom sheet-metal skins, trims and light framing without a separate pilot operation.
- Self-Drilling Point
- A2 Stainless Steel
- Integral Washer Head
- Sheet-Metal Thread
Introduction de produit
This stainless steel self-tapping screw combines a drill-point tip, coarse sheet-metal thread and hex washer head in one fastener. The cutting flutes form a pilot opening through compatible light-gauge steel, after which the thread draws the components together. The integral flange spreads seating pressure across trim or panel facing, while stainless construction supports clean, corrosion-resistant installation hardware.
Key Features
Coarse threads develop engagement in light-gauge framing and folded trim.
The hex washer head supports positive driver engagement and distributed seating pressure.
A2 stainless steel provides a clean bright finish and practical interior corrosion resistance.
Préoccupations du client produit
Thin cleanroom facings require a fastener that starts predictably, seats without excessive indentation and resists corrosion after installation.
Conventional points skate on smooth metal skins.The self-drilling flute establishes the hole before the thread engages.
Small heads concentrate load and distort trim.An integral washer flange spreads seating force over a wider area.
Over-driving strips light-gauge thread engagement.Matched screw length, drilling capacity and controlled driver torque preserve the formed thread.
Plated carbon-steel fasteners can stain in humid service.A2 or A4 stainless grade is selected for the exposure conditions.
