Fastening systems for demanding applications

WORKWEAR – Form and Function

The workwear sector usually places high functional demands on snap fasteners and closure solutions. This is where YKK STOCKO can draw on decades of experience. In our development department, we are constantly researching new innovative materials for our closure solutions and testing them in accordance with international standards and norms.

The demands on the quality of a push button are manifold:

  • Easy handling during closing and opening (often with only one hand)
  • High locking force
  • Temperature and heat resistance
  • longevity
  • Good washability without rust
  • Adherence to hygiene regulations
  • Water resistance
  • Sophisticated design and many design options

Closure systems for high demands on hygiene and industrial washability


Workwear that is industrially washed is subject to special requirements. For this reason, pushbutton closure systems made of corrosion-resistant stainless steel are the best solution.

In addition to intensive wear and tear, the washing process plays a decisive role in the service life and performance of the products. Washing substances and cyclic dewatering presses can degrease and deform the functional parts and strongly impair the closure. The result is pushbuttons that can no longer be opened or closed. This results in high repair rates.

For this reason, YKK STOCKO FASTENERS offers various stainless steel versions of the ACTIVO, SOLIDO and PREMEO systems as PROTECT-S variants, which are best suited to the respective requirements.


Maximum protection with the system DP 300

The DP300 fire-retardant push-button system is made entirely from high performance plastic material and is therefore ideal for workwear protective clothing. It meets all relevant certifications for workwear, automotive and technical applications.

This makes DP 300 a closure system that meets the highest demands for safety and efficiency. DP300 is a lightweight, comfortable push button system, ideal for hazardous work environments. It reliably protects against thermal damage caused by high temperatures or electric arcs. DP 300 is also waterproof.



PREMEO PROTECT-WP does not allow water to penetrate, even under extreme conditions. The patented YKK push-button system was specially developed for waterproof clothing – and retains its full closing power even after thousands of applications. The integrated sealing element protects against moisture and keeps the garment windproof and waterproof.


Functionality with high fashion demands

PREMEO DESIGN, the modern push-button system, sets accents and convinces with its long service life. High-quality materials for comfortable and reliable opening and closing. The closure highlight – Exclusively from YKK.
