Subheadings
Products classified under HTS 8463.20.00
Haas TL-1 CNC Thread Rolling Machine
The Haas TL-1 is a CNC-controlled thread rolling machine designed for producing precise external threads on metal bolts, screws, and fasteners by cold forming without removing material. It uses two hardened dies to displace metal radially, creating strong, accurate threads ideal for high-volume manufacturing. Classified under HTS 8463.20.00 as a machine tool for working metal without material removal via thread rolling process.
Parkson PR-32M Hydraulic Thread Roller
The Parkson PR-32M hydraulic thread rolling machine produces M3 to M32 diameter threads on ferrous and non-ferrous metal rods at high speeds using planetary die rolling technology. Ideal for automotive fasteners and construction bolts, it forms threads by material displacement for superior strength over cut threads. Falls under HTS 8463.20.00 for its specialized metalworking function without chip removal.
Wafios RT 40/6 Thread Rolling Machine
Wafios RT 40/6 is a precision thread rolling machine for wire sizes up to 6mm, producing straight and tapered threads on fasteners, automotive components, and bicycle parts through two synchronized rolling dies. Its robust construction handles high production rates while maintaining tight thread tolerances. HTS 8463.20.00 classification applies to this dedicated cold thread forming equipment for metals.
Landis Lund LR 16-45 Thread Roller
The Landis Lund LR 16-45 thread rolling machine handles parts from 3/16 to 1-3/4 inch diameter, ideal for large diameter bolts used in heavy construction and oilfield applications. It employs adjustable flat dies for custom thread profiles with minimal material waste. Properly classified in HTS 8463.20.00 as specialized equipment for cold working metal threads.
Optima TRM-25 CNC Thread Rolling Center
Optima TRM-25 is a modern CNC thread rolling center with automatic bar loading for unmanned production of M6-M25 bolts and special fasteners. Features 4-axis control for complex thread geometries including multi-start and ACME threads. HTS 8463.20.00 covers this advanced cold forming machine tool operating without material removal.
