Product Overview
Produce high-quality power threads with our ACME Full Profile laydown threading inserts. Compliant with ANSI/ASME B1.5 standards, these tools generate the specific 29° trapezoidal profile required for American lead screws and jacks.
Featuring a “Full Profile” geometry, these carbide threading inserts cut the thread groove and finish the crest diameter in a single pass. This ensures the thread form is precise and burr-free, which is critical for minimizing friction in power transmission assemblies.
Key Features & Benefits
- Standard Compliance: Precision ground to maintain the 29° angle, distinguishing it from the 30° Metric TR standard.
- The 16ER Standard: Our 16er threading inserts (3/8″ I.C.) efficiently handle the most common pitch range (16 TPI to 8 TPI) found in general machinery.
- Heavy Duty Capability: For coarser threads (6 TPI to 4 TPI), we utilize larger 1/2″ (22mm) and 5/8″ (27mm) I.C. inserts to ensure tool rigidity.
- Directional Options: We offer comprehensive solutions, including standard right-hand tools and left hand thread insert models (e.g., 16EL 10 ACME) for bi-directional lead screw manufacturing.
