Cross recessed countersunk head tapping screws in carbon steel, sized ST2.9x9.5, are engineered for secure, flush-fastening in a range of assemblies. Their self-tapping design cuts its own thread as you drive, speeding up installation and reducing the need for pre-tapping in many substrates. The cross recessed (Phillips) drive provides broad compatibility with standard bits, while the countersunk head sits flush to deliver a clean, professional finish.

Constructed from robust carbon steel, these screws balance strength and practical utility for everyday fastening tasks. The ST2.9x9.5 dimensions strike a practical balance between a compact profile and dependable grip, making them well-suited for thin panels, cabinetry, electronics enclosures, mounts, and other assemblies where a low-profile fastener is desired.

Key features

• Cross recessed Phillips drive for reliable engagement and broad bit compatibility.
• Countersunk head ensures a flush surface after installation to avoid snagging or interference.
• Self-tapping capability reduces prep work by forming threads directly in the substrate.
• Carbon steel construction provides solid strength for everyday mounting and fixtures.
• ST2.9x9.5 dimensions offer a compact, versatile size for thin materials and tight spaces.

Ideal uses

• Metal panels, instrument housings, and electrical enclosures where a clean, unobtrusive fastening is preferred.
• Furniture assembly and cabinetry projects that benefit from a flush, low-profile finish.
• DIY or light industrial applications requiring dependable self-tapping fasteners with a standard Phillips drive.

Installation tips

• Use a sharp Phillips bit and apply steady, even torque to prevent cam-out and preserve thread integrity.
• For very hard substrates, consider drilling a pilot hole to guide the screw and improve drive accuracy.
• Avoid over-tightening to maintain the integrity of the thread and the flush seating of the countersunk head.
