Tap for Non-Anodized Screws

This II-type self-tapping tap set provides seven graduated diameters (4.0 mm–7.0 mm) to fully meet the needs of pedicle screw insertion in thoracolumbar procedures. 

Made from high-strength stainless steel in a one-piece structure, the cutting edges undergo special surface hardening for superior bone-cutting efficiency and fatigue resistance. 

Designed for constrained percutaneous channels, it enables low-resistance, high-precision pedicle thread preparation in a single step.

Premium Materials – Medical-grade stainless steels (05Cr17Ni4Cu4Nb, 465, 316L, 304) with electrolytic polishing for high fatigue resistance and minimal tissue friction.

Full Graduated Range – Seven diameters: 4.0 mm, 4.5 mm, 5.0 mm, 5.5 mm, 6.0 mm, 6.5 mm, 7.0 mm to match diverse pedicle anatomies and screw sizes

High-Efficiency Self-Tapping Design – Optimized spiral flutes and cutting geometry allow simultaneous cortical penetration and precision thread formation, eliminating separate drilling and tapping steps.

Integrated MIS Workflow – Works seamlessly with guidewires and sequential dilators; allows post-tapping integrity checks with a ball probe to reduce pedicle breach risk.

Broad System Compatibility – Fits mainstream MIS pedicle screw systems (5.5 mm, 6.5 mm, 7.5 mm) for fractures, deformity correction, and spondylolisthesis reduction

Precise Anatomical Fit – Complete 4.0–7.0 mm range adapts to fine or large pedicles, ensuring optimal screw-pedicle match and reducing intraoperative instrument change risk.

Streamlined Efficiency – Combines drilling and tapping in one step, reducing channel instrument exchanges and shortening preparation time—especially beneficial in multi-level surgery.

Durable & Compatible – One-piece forged stainless steel for high bending strength and wear resistance; compatible with leading MIS screw-rod systems and accessory tools.
