It’s key features are:-
1.Self-Tapping/Drilling Capability: Eliminates the need to pre-drill a pilot hole in many sheet metal or softer applications, saving installation time
2.Head & Drive Styles: Commonly available with Hex Washer/Flange heads (driven by a spanner or socket for high torque) or Phillips Pan/Flat heads (driven by cross-recess bits)
3.Load Distribution: Flanged or hex-washer variants distribute clamping pressure evenly across the fastened surface to prevent damage
4.Material Options: Frequently manufactured from hardened carbon steel with bright zinc plating (BZP) for indoor corrosion resistance, or 304/410 stainless steel for enhanced outdoor and industrial durability
