NUTS - Advanced Compensation

Product Description

The Advanced Compensation Nut (ACN) provides an efficient and economical solution to any gap and tolerance issues that may have your assembly efficiency pinned down. Simply snap the ACN in place, insert the bolt and as it gets tightened, the system auto‐adjusts to bridge the gap between components to produce a stronger, more durable assembly.

  • Ensures a stronger, tension‐free and distortion‐free assembly
  • Installs quickly and easily
  • Design prevents excessive panel overcompensation and “tin‐canning” issues that can be created by other nuts
  • Ideal for use with wide range of interior and exterior applications including instrument panels, doors, roof and headlight/front end systems
  • Made from ultra‐high strength steel with anti‐galvanic corrosion resistant finish
