Metric Fine Thread Hex Nuts Manufacturers

-- Steady & Reliable Manufacturer --

Introduction

Metric Fine Thread Hex Nuts are utilized in applications requiring precise adjustment, superior locking ability against vibration, and maximum strength in thin-walled sections. Unlike coarse thread (standard) nuts, fine threads have more threads per unit length, resulting in a larger stress area, making the joint stronger and less prone to loosening. They are commonly found in the highly regulated automotive, aerospace, and precision machinery sectors.

Applications

  • Precision Machine Tools: Used for fine adjustment on slides, gears, and tool mounts.

  • Automotive Engine Components: Where extreme vibration resistance and high clamp load are needed in compact spaces.

  • Hydraulic and Fluid Power: Providing high pressure-holding capacity in port connections.

  • Gauges and Instrumentation: Used for micro-adjustments and critical locking on measuring equipment.

Advantages

  • Increased Holding Power: The increased number of threads in engagement distributes the load better, making the joint stronger.

  • Better Sealing: Finer thread pitch minimizes the spiral leakage path for gasses and fluids.

  • Finer Adjustment: A smaller angle of rotation is required per linear movement, allowing for more precise positioning.

  • Reduced Loosening: More resistant to dynamic vibration forces compared to coarse thread.

Payment & Shipping

We provide fast turnaround on custom batches of fine thread nuts. Payment via TT is accepted. Due to their specific nature, nuts are labeled with both diameter and pitch (e.g., M10x1.25) and shipped in specialized, compartmented boxes to prevent mixing with coarse thread fasteners.

FAQ

  • Q: Why are metric fine threads generally more expensive than coarse threads?
  • A: Fine threads require tighter manufacturing tolerances and more precise machining to produce the smaller pitch, increasing production costs and making inspection procedures more stringent.
  • Q: What is the main drawback of using fine thread nuts?
  • A: Fine threads are more susceptible to cross-threading if misaligned during initial assembly. They are also more easily damaged by nicking or burrs, and the threads are more prone to galling, especially in stainless steel applications.
