UNF Tap 1/4-28

The UNF Tap 1/4-28 from ALLSTAR PERFORMANCE is a precision threading tool designed for fabricators, engine builders, and automotive enthusiasts who require accuracy when creating internal threads in various materials. This tap is particularly useful for applications such as custom intake manifolds and coolant bypass installations.

The 1/4-28 UNF (Unified National Fine) specification indicates that this tap cuts a 1/4-inch diameter thread with 28 threads per inch, providing a fine-pitch geometry that enhances clamping force and vibration resistance. This design is critical for applications that may experience thermal cycling and combustion pressure.

Professional mechanics and engine builders will find this tap beneficial for various applications, including engine blocks and fuel systems. Its compatibility with aluminum, steel, and cast iron makes it a versatile tool for custom fabrication work.
