machines as well as, if needed, the integration into 
automated serial production workflows.

Ever since 1927, KVT-Fastening has stood for 
experience, solution-driven know-how, unique 
expertise in development and consultancy as well 
as the ultimate in reliability. Since December 
2012, KVT-Fastening is a member of the Bossard 
Group. Bossard is a leading provider of intelligent 
solutions for industrial fastening technology. The 
range includes global sales, technical consulting 
(engineering) and logistics of fastening technol-
ogy components and bolts. Customers benefit 
from the extension of competencies in industrial 
fastening technology and from an optimally 
enhanced product or service portfolio.

High-performance solutions from KVT-Fastening 
are found wherever absolutely safe and secure 
connections are essential. These small but 
extremely resilient components play key roles 
where it matters most – whether in the electronics 
and energy sector, the automotive and transporta-
tion industries, aviation and aerospace, engineer-
ing and construction, precision engineering, or 
medical equipment.

KVT-Fastening does not just supply standard 
products and individual components, but also pro-
vides close and active customer support in the 
search for ideal solutions, particularly when spe-
cific requirements must be fulfilled. This portfolio

Efficient fasteners even for very thin components

In countless areas of modern industry, very thin and 
very lightweight components such as metal plates, 
PC boards or plastic pieces are put to use. There is 
the need to permanently connect them together 
securely, all the while guaranteeing high values of 
torque-out and pullout. At the same time, manufac-
turers expect simple, low-cost assembly.
As far back as 1942, PEM

®

 developed a self-clinch-

ing fastener that was able to meet these challenges. 
With increasing success and broad industry accep-
tance, the product line has been continually expand-
ed, but even so the basic advantages have remained 
the same: PEM

®

 self-clinching fasteners give 

high-performance, are easy to install and save time 
and expense.
PEM

®

 self-clinching fasteners are placed into a 

mounting hole in the workpiece. There the self-
clinching fastener displaces material in the hole 
area. This material flows by means of cold deforma-

tion into an undercut in the region near the fasten-
er’s shank serrations or a special head design than 
prevents the component from rotating – the self-
clinching fastener becomes an integral part of the 
workpiece. In addition, PEM

®

 self-clinching fasten-

ers cause no damage or bulges on the rear side of 
the workpiece. PEM

®

 self-clinching fasteners are 

put to use in areas ranging from electronics and the 
automobile industry, to the construction of machines 
and apparatus, through to aeronautics and space – 
and in each case they guarantee a durable, secure 
anchoring.

Advantages

n  

 Extreme load capacity even in metal sheets as 
thin as 0.5 mm

n  

 No special preparation of the mounting hole 
necessary

n  

 No recutting of threads

n  

 Also ideal for coated surfaces

n  

 High positional accuracy
