Fastening nylon maxi-screw

It is well known that fastening of concrete segments in galleries requires use of maxi-screws with partially threaded shank and hexagonal head.
Plugs, instead, are integral with the segment, and feature an internal threading for screwing them on the screw shank.
The demand for materials with extremely high corrosion resistance is on the rise because of the need to conform the connector's product life with the infrastructure's.
InnoTek has offered on the market a new segments fastening system.
It is a new nylon/fibreglass maxi-screw with steel core guaranteed to provide the mechanical resistances of the traditional system while offering incredibly superior duration.
