RIDGID Unified National Fine (UNF) Bolt Thread

RIDGID Unified National Fine (UNF) Bolt Threading Dies are precision-engineered cutting tools designed to produce accurate, consistent external fine threads on bolts, studs, threaded rods, and industrial fasteners. Manufactured for professional threading applications, RIDGID UNF bolt threading dies provide dependable cutting performance, excellent durability, and consistent thread quality. These replacement cutting dies are ideal for machine shops, mechanical contractors, industrial maintenance departments, equipment repair facilities, and metal fabrication professionals requiring precise fine-thread fastening solutions.

RIDGID UNF Bolt Threading Performance

RIDGID UNF bolt threading dies produce Unified National Fine threads conforming to ASME B1.1 specifications. UNF threads feature a 60-degree thread angle and a finer thread pitch than Unified National Coarse (UNC) threads of the same nominal diameter.

The finer thread design provides more threads per inch, allowing precise adjustment, increased tensile stress area compared with corresponding UNC threads, and reliable fastening performance in applications requiring controlled assembly.

• Die Material: Precision-machined cutting steel, depending on configuration.

• Available Sizes: Selected fractional-inch bolt diameters.

• Die Compatibility: Appropriate RIDGID manual bolt threading die heads and compatible threading equipment.

• Replacement Design: Cutting dies selected according to bolt diameter, thread pitch, and die head model.

RIDGID UNF Bolt Threading Applications

RIDGID UNF bolt threading dies are ideal for automotive repair, industrial machinery maintenance, precision mechanical assemblies, equipment fabrication, and replacement fastener production. Fine-thread fasteners are frequently used where controlled adjustment, secure clamping, and precise threaded engagement are required.

Professional RIDGID UNF Replacement Bolt Threading Dies

RIDGID UNF bolt threading dies provide accurate thread formation, reliable cutting performance, and long-lasting industrial durability. Selecting the correct nominal bolt diameter, threads per inch, and compatible die head helps ensure proper thread engagement.

Using suitable RIDGID thread cutting oil reduces friction, improves cutting efficiency, and extends die service life.
