High-Quality Truss Head Screws

What is a Truss Head Screw?

A truss head screw (also commonly referred to in the industry as a mushroom screw) is a highly specialized fastener easily identified by its exceptionally wide, low-profile dome. Manufactured from premium, industrial-grade materials—most notably highly corrosion-resistant stainless steel—these slotted-head fasteners are engineered to provide a smooth, secure hold. Our standard inventory includes a versatile range of lengths from 3/16 inch up to 1 inch to perfectly accommodate your specific assembly requirements.

Design Features and Mechanical Advantages

Because of their distinct oversized and flattened geometry, truss head screws offer several critical structural advantages over standard pan or round head fasteners:

• Tamper-Resistant Dome: The significantly lower profile is specifically engineered to sit nearly flush against the mating surface. This smooth, sloping design prevents unauthorized tools or pliers from gripping the head, providing an essential layer of security and tamper resistance.
• Extra-Wide Bearing Surface: Truss head screws are frequently manufactured with a much larger head diameter than other screw types. This wider footprint expertly distributes clamping pressure over a larger area, heavily reducing the risk of crushing or damaging thin sheet metals and delicate substrates.
• Snag-Free Finish: By eliminating tall, protruding screw heads, they prevent moving mechanical parts from snagging and stop debris from accumulating, ensuring a clean and professional final appearance.
