Product Overview
Handle extreme unidirectional forces with our American Buttress (ABUT) laydown threading inserts. Compliant with ANSI B1.9 standards, these tools produce the distinctive 7°/45° thread profile used in high-stress machinery where force is applied in one direction, such as vices, breech locks, and screw jacks.
Featuring a “Full Profile” geometry, these carbide threading inserts cut the thread groove and finish the crest in a single pass. This ensures the 7° load-bearing flank is geometrically perfect, maximizing the thread’s shear strength.
Key Features & Benefits
- High Thrust Capacity: The near-vertical 7° flank transmits massive axial loads, while the 45° back flank ensures strength at the root.
- The 16ER Standard: Our 16er threading inserts (e.g., 16ER 12 ABUT) efficiently handle the most common medium pitches, fitting standard ISO tool holders.
- Complete Range: Available in small 1/4″ (11mm) sizes for tight spaces and robust 1/2″ (22mm) sizes for coarser pitches up to 6 TPI.
- Directional Options: We provide comprehensive solutions, including left hand thread insert models (e.g., 16EL 10 ABUT) for complex mechanical assemblies.
