YOUR ADVANTAGES


During installation distorsion-proof hexagon nuts made of stainless steel guarantee high safety and strength compared to thread inserts.

On ultra-modern CNC machining centers our technicians produce block flanges in all usual sizes and dimensions.
The hexagon grooves are milled with millimeter precision. Then the stainless steel hexagon nuts are inserted with high fitting accuracy, by request  (1.4301) or (1.4571). 
The hexagon nuts are fitting tightly in the CNC machined groove and will not get lost during installation.  So you can count on a strong and distorsion-proof assembly part and enormous cost benefits. 

We can deliver directly from stock at a reasonable price. Just send us your inquiry.

Other designs and material combinations can be delivered on request.
All items you will also find in our webshop.
