Key Features and Specifications
Drilling Capacity: Designed with a specialized spiral drill point that can cut through steel and aluminum ranging from 6.0mm up to 25.5mm in thickness.
Material & Construction: Typically manufactured from high-strength SAE1022 hardened carbon steel, Which is a low-carbon steel (with roughly 0.18%–0.23% carbon and 0.70%–1.00% manganese) detailed in data from MW Components. Because of its low core carbon content, SAE 1022 does not through-harden deeply to high hardness throughout its cross-section via simple heat-treat-and-quench methods alone. Instead, it is typically case-hardened (via carburizing, carbonitriding, or nitriding) to create a hard, wear-resistant outer surface while keeping a tough, ductile core.
Head Type: Hex washer head design (M8-20 diameter, 8.0mm screw size with a ~19mm washer diameter or integrated flange) which provides a wide bearing surface to distribute clamping pressure and prevent surface damage.
Drive Type: Driven using a standard hex socket or nutsetter (typically a 13mm hex drive).
Threads: Fine-pitch full threads that cut their own mating threads into heavy-gauge steel.

Common Applications
Structural Steel Connections: Fastening thick steel plates, structural framing, and gantry or suspension systems.
Façade and Cladding Installation: Securing heavy metal panels and exterior building envelopes to steel support columns or stud walls.
Heavy-Duty Construction: Anchoring base plates or steel sub-framing where traditional self-drilling screws (which usually max out at thinner gauge metals) fail to penetrate.
