Floating Thread Rivet Nuts | Sherex by PEM Tolerance Compensation - PEM Europe

Floating Thread Rivet Nuts

Sherex® by PEM® floating thread rivet nuts are engineered specifically for assemblies where hole misalignment between mating components creates installation difficulties. The internally floating thread design allows the threaded insert to self-align within a defined range during fastener engagement, accommodating tolerance variation without requiring rework or adjusted hole positions.

RIV-FLOAT® is a patented product from Sherex® by PEM® that's available in a standard version and a short version, which accommodates applications with tighter backside clearances. RIV-FLOAT® can be installed using standard rivet nut tooling.

Floating thread rivet nuts are a cost-effective alternative to precision hole preparation or manual alignment operations, significantly reducing assembly time and rework rates in complex multi-component structures.

Key Features

  • Internally floating thread compensates for hole misalignment between mating parts
  • Self-aligning design reduces assembly time and eliminates rework
  • Accommodates positional tolerance variation in production environments
  • Installed as a standard rivet nut — no special tooling required
  • Available in round body design for standard round hole installation
  • Thread sizes from M4 - M6 (metric)
  • Steel and stainless steel material options

Typical Applications

  • Multi-component automotive sub-assemblies with tolerance stack-up challenges
  • Electronic equipment chassis assembly with multiple attachment points
  • Industrial machinery where component-to-component alignment is variable
  • Any assembly where hole-to-hole positional accuracy cannot be consistently achieved

Product Series

The Sherex® by PEM® floating thread range is based on the RIV-FLOAT® technology platform, providing a comprehensive solution for tolerance compensation in a variety of installation scenarios. See the RIV-FLOAT® product family pages for full dimensional and installation data.
