Hexagon Thin Nuts DIN 439 Manufacturers

Introduction

DIN 439 Hexagon Thin Nuts, often referred to as half nuts or jam nuts, are designed to be thinner than standard nuts, making them ideal for applications with limited clearance or as a locking device. When used in pairs (a jam nut against a full nut), they provide an effective mechanical lock against loosening caused by vibration and thermal expansion, ensuring long-term joint security.

Applications

  • Locking Mechanism: Used as the second nut in a double-nut assembly to resist vibration.

  • Threaded Rod and Tie Rods: For locking a component onto a rod without needing a thick nut.

  • Low Clearance Areas: Used in machinery where height constraints are critical.

  • Precision Adjustment: Used as adjustable stoppers or positioning devices on machine shafts.

Advantages

  • Cost-Effective Locking: Provides a robust mechanical lock without the cost of specialized lock nuts (e.g., nyloc).

  • Space Saving: Significantly reduces the vertical height of a fastened joint.

  • Versatility: Available in a wide range of materials and finishes to suit nearly any environment.

  • High Reusability: Unlike some single-use locking nuts, they can be reused multiple times.

Payment & Shipping

Thin nuts are high-volume commodity items. We offer attractive pricing for bulk orders with favorable payment terms like TT 60 Days for established clients. Shipments are consolidated and palletized for optimal container loading and efficiency.

FAQ

  • Q: Which nut should be tightened first in a double-nut system?
  • A: For the most effective locking, the thinner jam nut should be tightened first with moderate torque, and the thicker standard nut should then be fully tightened against the jam nut. This creates opposing forces on the threads.
  • Q: Can DIN 439 nuts be used in structural applications?
  • A: While they can be used in locking pairs on structural bolts, they are not typically rated for the primary load-bearing capacity alone due to their reduced height. Always rely on a full-height structural nut for the main clamping load.
