Zakrętka okienna Window Fastener Half-Turn 7mm Spindle Yellow Zinc Plated Steel

Product Overview

The Zakrętka okienna (półzakrętka) is a window fastener component, widely applied in residential and light commercial window fabrication and repair. Its 7 mm spindle and yellow zinc-plated steel construction provide secure window closure with enhanced corrosion resistance for long-term durability, making it suitable for indoor window assemblies in standard climatic conditions.

A key differentiator of this model is the yellow zinc (ocynk żółty) coating, which offers greater resistance to oxidation and wear compared to standard or untreated finishes. This added layer of protection reduces the frequency of replacements due to rust, particularly benefitting fabrication shops and maintenance contractors handling large volume installations or repairs.
