clamping loads, where excessive 
compression could otherwise damage or 
deform the component.
Sealing inserts:
Certain applications also require 
the fastening point to contribute to 
environmental protection. Sealing inserts 
can help restrict the passage of liquids, 
dust or other contaminants and may 
therefore be considered for electronic 
housings, outdoor equipment and other 
enclosed assemblies.
Testing before production
Selecting an appropriate fastening 
method involves more than matching an 
insert or screw to a nominal hole size. 
The grade of plastic, wall thickness, 
boss design, installation parameters and 
expected service loads can all influence 
joint performance.
From PSM CELADA Fasteners’ 
experience, pre-production testing can 
be particularly valuable when a new 
material is introduced or a component 
moves from prototype to series 
production. Torque, pull-out resistance 
and installation behaviour can be 
assessed under representative conditions

to identify potential issues before full 
production begins.
Changes in material formulation can 
also affect fastening performance. Even 
when the component geometry remains 
unchanged, differences in reinforcement, 
additives or material suppliers may 
alter how the plastic behaves during 
installation and under load.
Considering the wider 
manufacturing process
As PSM CELADA Fasteners emphasises, 
the fastener should be considered 
as part of the complete joint and 
assembly process rather than as an 
isolated component. 
“Decisions made during the 
early stages of development 
can influence installation 
speed, repeatability, component 
geometry and long-term 
joint performance,” 
explains the team at PSM 
CELADA Fasteners. 
Production volume is another 
consideration. A fastening method suited 
to prototype or low-volume assembly may 
not necessarily be the most appropriate 
solution for an automated production line, 
where feeding, orientation, installation 
speed and process monitoring become 
increasingly important.
For manufacturers working with 
plastic components, understanding the 
interaction between the material, fastener 
and installation process can help create 
a more consistent and reliable assembly. 
Rather than treating the fastener as an 
isolated component, considering the 
complete joint from the outset can help 
avoid problems later in production.
