Safety mesh fastener
EN 620:2002+A1:2010 sets the requirement, that shields shall only be possible to open with a tool and the fixing must stay fixed on the structure or the shield even when the shield is removed.
The special bolt with a big washer fixed with a metal wire, does this job. Works like a simple nut fixed on a bolt, or the other way around, as you wish.
This product is a good example coming from a customer wish. Designed to meet the needs and to be a bit better than what’s at the market at the moment. In this case a bit bigger and made of AISI316.
