Truss head tapping screws are engineered for applications requiring wide bearing surfaces and minimal surface intrusion. Their distinctive low-profile, large-diameter heads offer superior holding power without damaging soft materials, making them ideal for securing sheet metal, plastic panels, and light-duty fixtures.
These screws are commonly manufactured in stainless steel grades such as 304 and 410 for optimal corrosion resistance and strength, with diameter sizes ranging from M2.9 to M6.3 and standard lengths from 6mm to 50mm. Drive types include Phillips and Torx, providing excellent torque control during installation. Their self-tapping thread design, typically Type AB or B, allows for secure engagement without pre-drilling, streamlining assembly processes.
Surface finishes such as zinc plating, black oxide, and nickel coating enhance durability and aesthetic compatibility with various materials. Conforming to DIN 7981 or ANSI standards, truss head tapping screws are a popular choice in HVAC units, electrical enclosures, and appliance manufacturing.
Their large head diameter prevents pull-through, especially in thin or brittle materials, making them essential in assemblies where aesthetics, strength, and efficiency are critical.
