We specialize in high-precision CNC machining and custom threading services. Our capabilities cover a wide range of international standards, ensuring compatibility for global industrial applications. Whether you need Metric fasteners or North American pipe threads, our engineering team delivers tight-tolerance threads for critical sealing and mechanical assembly.
| Thread Type | Category | Full Name | Thread Angle | Taper | Key Characteristics & Common Applications |
| M | Metric | Metric General Purpose | 60° | None (Parallel) | Global standard. Defined by pitch (mm). Used for general mechanical fastening and assembly. |
| UNF | Unified | Unified Fine | 60° | None (Parallel) | Fine pitch for high strength and better adjustment. Common in aerospace and automotive industries. |
| UNEF | Unified | Unified Extra Fine | 60° | None (Parallel) | Extra fine pitch used for thin-walled tubes and high-precision adjustment instruments. |
| UNS | Unified | Unified Special | 60° | None (Parallel) | Customized threads with non-standard combinations of diameter and pitch for specific designs. |
| BSPP (G) | British | British Standard Pipe Parallel | 55° | None (Parallel) | Also known as G thread. Requires a washer, gasket, or O-ring to achieve a leak-proof seal. |
| BSPT (R/Rc) | British | British Standard Pipe Taper | 55° | 1:16 | Also known as Whitworth Taper. Achieves a seal via the fit of the threads themselves + sealant. |
| NPT | American | National Pipe Taper | 60° | 1:16 | Standard American pipe thread. Relies on thread interference and the use of PTFE tape or sealant. |
| NPTF | American | National Pipe Taper Fuel | 60° | 1:16 | Known as Dryseal. Designed to provide a leak-free seal without the need for additional sealants. |
We specialize in the manufacturing of precision machined custom cnc pipe fittings using a variety of materials including carbon steel, stainless steel, aluminum, and brass.
