Meet the Wiseman Threading Tools Spiral Flute Machine Nut Tap in metric M16x2—a high-speed steel ground thread tap designed for fast, reliable internal threading in metal parts. This uncoated, general‑purpose tap adheres to BS 949 dimensions, delivering consistent thread forms for a wide range of applications. The spiral flute geometry enhances chip evacuation for smoother cutting in through-holes, while the right-hand thread aligns with standard fastener practice. The tool’s design is optimized for machine tapping, making it a dependable choice in production and workshop settings.

• High-speed steel ground, uncoated—a robust, precise tap built for durability and dependable performance across common metals.
• Spiral flute—engineered to rapidly evacuate chips, reduce binding, and improve thread quality in through-holes.
• Machine tap with a square drive end—designed for secure mounting in tapping heads, CNC centers, drill/tap rigs, and other power tapping setups.
• BS 949 dimensions—ensures standard metric thread form and compatibility with standard tapping charts and hole sizes.
• Size M16x2—16 mm nominal major diameter with a 2 mm pitch, a common specification for durable, precise internal threads in structural components and machinery housings.
• Right-hand thread—fits the vast majority of standard assemblies and fastener systems for straightforward installation and maintenance.

Ideal for engineering workshops, automotive fabrication, and maintenance departments, this tap excels in steel, cast iron, and aluminum where quick, clean internal threads are essential. It’s especially effective in production environments where chip clearance and consistent thread quality drive throughput and reduce downtime. When used with proper cutting fluid and steady feeds, it delivers reproducible results—from prototypes to full production runs.

Practical tips for best results: lubricate with an appropriate threading fluid to maximize tool life, start at a conservative feed rate to establish alignment, and back off occasionally to clear accumulated chips. Ensure the workpiece is securely clamped to minimize chatter, and use a tapping fixture or machine head designed for power tapping to capitalize on the spiral flute’s chip‑evacuation benefits. This Wiseman M16x2 tap is your reliable partner for precise, repeatable internal threads in metal components.
