Screw-ST4.2x19-Cross pan head tapping

Screw-ST4.2x19-Cross pan head tapping is a purpose-built self-tapping screw designed for quick, secure fastening in thin metal panels, lightweight enclosures, and DIY projects. With a precise 4.2 mm diameter and 19 mm length, this fastener fits snugly where space is at a premium and a clean, professional finish matters.

Drive type and head style matter when speed and reliability count. This screw features a Phillips cross drive for steady torque and reduced cam-out, paired with a pan head that distributes load over a broad bearing surface. The result is a dependable coupling that stays secure even in vibration-prone environments, while the rounded head provides easy access for hand or power drivers in tight areas.

Key features

• 
  Self-tapping thread creates its own path in compatible materials, eliminating the need for pre-tapped holes and speeding up assemblies.
• 
  Phillips (cross) drive delivers reliable engagement and minimizes driver slip in constrained spaces.
• 
  Pan head offers a generous bearing surface for even load distribution and a clean surface finish.
• 
  Precise size: ST4.2x19 ensures consistency across parts and aligns with standard sheet metal and enclosure designs.

Ideal use cases

• Fastening thin sheet metal panels in electronics enclosures, small appliances, and light machinery.
• Securing plastic housings to metal frames where a durable, non-flush fastener is acceptable.
• DIY projects that require quick assembly of lightweight metal components or modular enclosures.

Installation tips

• Prepare a compatible pilot hole if your material requires it to ensure clean thread formation and prevent tearing.
• Keep the screw perpendicular to the joining surface to seat the pan head evenly.
• Use a proper Phillips driver to maintain control and prevent slipping during tightening.
• Drive until the head sits flush with the surface for a neat, secure finish—avoid overtightening that could strip the thread.

Why this screw stands out

• Designed to simplify assemblies by cutting its own thread, reducing setup time and the risk of cross-threading.
• Consistent ST4.2x19 dimensions support reliable performance across multiple projects and components.
• Ideal for applications where a quick, sturdy fastening is needed in metal enclosures, housings, and light-duty chassis.
