Temporary Fasteners

The temporary fastener is a solution proposed to customers solutions for their pre-assembly challenges. Our technical field experts have acquired a complete and thorough knowledge of aircraft pre-assembly and we manufacture today solutions for the following situations: 

  • Simple clamping
  • Drilling template holding and metal or composite sheets clamping through the template
  • Sealant/liquid shim squeeze out and drying
  • Pre-load retaining
  • Gap measurement

 Clampberry temporary fasteners

 

Plunger types or lead thread standard temporary fasteners allow the pre-assembly of all kind of material elements. Spring loaded or not, they are designed for efficient clamping in rubber sealant or resin applications.

 Special high performance temporary fasteners answer to particular requirements such as :
- Large diameters
- Hard tool holding
- Wide structure thickness
- Clamping through hard tool bushings
A complete range of standard or special tools ensure adjustable pre-loads of the assembly as well as access in confined areas.

 The range of CLAMPBERRY temporary fasteners is unique in the aerospace market. Built step by step to answer successive customer challenges, it represents today dozens of standards for various applications which can be declined in different diameters and grip ranges. Depending on the environment of the installation, on the structure to pre-assemble, on the tension to sustain, on the application to secure, we can provide the appropriate pre-assembly solution. The product range is wide but here are a few of our major technical concepts:

  • for small thickness sheets pre-assembly under low pre-load, our manually operated Series 1000 and 1100
  • for rubber sealant applications, our most common CLY-26/-28/-41/-42/-44H series
  • for drilling template holding and further structure clamping:
    – our combination of CLY-80 and CLY-81 series for standard preassemblies,
    – our CLY-355, CLY-351 and CLY-352 series for confined areas and restricted environments
  • for more complex and precise pre-assemblies, our CAL concept
  • for composite structures, our CLY-CC, CLY-CCG, CLY-348CC, CLY-350...
  • for automated pre-assemblies, our newly CLY-CCTFR, CLY-61 and related effector

 CLAMPBERRY temporary fastener solutions are also referenced as CLY pins.
