Specialty Inserts & Engineered Fasteners

Advanced Threading Solutions for Plastics, Alloys, and High-Vibration Assemblies

Standard fasteners don’t work for every application. When you are dealing with brittle plastics, vibration-heavy environments, stripped threads, or misaligned mounting points, you need an engineered solution.

Chemical Concepts supplies a complete range of Specialinsert® specialty fasteners designed to solve the most difficult manufacturing challenges in the automotive, aerospace, electronics, and fabrication industries.

Specialty Threaded Inserts and Fasteners

Engineered for Difficult Materials

  • Plastics & Resins: Heat-set, expansion, and self-tapping inserts for secure threads in thermoplastics and thermosetting plastics.
  • Light Alloys & Cast Iron: Heavy-duty self-threading bushes for maximum pull-out resistance.
  • Soft Materials: Deforming rivets that anchor into fiberglass, thin plastics, and rubber.

Assembly & Maintenance Solutions

  • Anti-Vibration: Rubber and isolated nuts for sound-proofing and dynamic loads.
  • Thread Repair: Helical wire inserts for reinforcing weak or stripped metal threads.
  • Quick Access: Quarter-turn fasteners and floating nuts for rapid maintenance and panel adjustments.
