4.2 mm x 12.7 mm Self-Tapping Truss Head Screw

When assembling or repairing electronic equipment, every fastener must offer dependable performance without compromising the integrity of your components. This self-tapping truss head screw, measuring 4.2 mm in diameter and 12.7 mm in length, provides a secure and lasting hold for a wide range of applications. Its robust design makes it an ideal choice for securing printed circuit boards, mounting enclosures, or attaching panels in audio devices and other electronic assemblies.

The self-tapping thread eliminates the need for pre-drilled holes, allowing for quick and efficient installation into plastic or soft metal substrates. The truss head profile offers a low, wide bearing surface that distributes clamping force evenly, reducing the risk of damage to delicate materials while providing a neat, finished appearance. This makes the screw particularly suitable for use in tight spaces where a standard pan or round head might protrude or cause interference.

Constructed from durable materials, this screw resists corrosion and maintains its holding power over time, ensuring your projects remain secure even under moderate vibration. Whether you are prototyping a new amplifier, repairing vintage audio gear, or building custom enclosures, this self-tapping truss head screw delivers the reliability and ease of use that electronics enthusiasts and professionals demand.
