Compensation Nut

ITW’s Advanced Compensation Nut (ACN) provides an efficient and economic solution to any gap and tolerance issues that may have your assembly efficiency pinned down.

The ITW Compensation Nut is designed to snap into a panel and auto adjust during the bolt installation process providing a solid carrying column of strength. Simply snap the ACN in place, insert the bolt and as it gets tightened, the system auto-adjusts to bridge the gap between components producing a stronger, more durable assembly.

  • Ensures a stronger, tension-free and distortion-free assembly
  • Installs quickly, easily and with minimal effort
  • Design prevents excessive panel overcompensation and “tin-canning” issues created by other nuts
  • Ideal for use with a wide range of interior and exterior applications including door, roof and headlight/front end systems


Our Advanced Compensation Nut is made from an ultra-high strength steel, allowing us to make it significantly lighter without compromising strength. A lighter compensation nut contributes to vehicle weight reduction and decreases freight charges while the added strength contributes to higher wear resistance, greater shear strength and a decreased rate of distortion, which improves quality.


  • High compressive load carrying capability
  • Fewer assembly components
  • Integrated anti-jam nut feature
  • Improved bolt alignment
  • Lighter weight
  • Anti upper & lower nut separation feature
  • Able to expand 0-8mm
  • Made from ultra-high strength steel with anti-galvanic corrosion resistant finish
