INDUSTRIAL WASHING Snap systems made of stainless steel

YKK stainless steel snap systems

Fastening systems for high hygiene and industrial washability requirements

Workwear that is industrially laundered is subject to special requirements. For this reason, snap fastening systems made of corrosion-resistant stainless steel are the best solution here.

In addition to the intensive wear and tear, the washing process plays a decisive role in the service life and performance of the products. Washing substances and cycle dewatering presses can degrease and deform the functional parts and severely impair the fastener. The result is snaps that can no longer be opened or closed. High repair rates are the result.

For this reason, YKK STOCKO FASTENERS offers various stainless steel versions of the FlexFix®, KNIPPER™ and S-Spring systems, which are available as PROTECT-S variants, that are best suited to the respective requirements.
