Our Wing Screws are sleek ergonomic components designed for projects where frequent manual adjustments are required.

What are Saddle Wing Screws

Saddle Wing Screw Knobs feature two curved t-arms that enhance grip and enable controlled twisting movement. The saddle-shaped design gives space for fingers to lock securely in place improving safety and control during use. They are manufactured from high-quality Phenolic Plastic (Duroplast) in a matte black finish which provides excellent durability and fluid movement due to its anti-slip texture.

Material Properties

Phenolic Plastic is a dense heat-resistant material commonly used in engineering and heavy-duty applications. It offers exceptional strength rigidity and resistance to heat and chemicals. This material is rated with a UL94 Flammability Classification of V-0 at a thickness of 3.0mm or more and V-1 at a thickness below 3.0mm.

Flame Ratings Explained

• HB: Slow horizontal burn under 3 inches per minute or self-extinguishing before 5 inches
• V-0: Vertical burning stops within 10 seconds with no flaming drips
• V-1: Vertical burning stops within 60 seconds with no flaming drips
