Stainless Steel Eyelet with Metal Washer 40.5 mm / 1.59 in Inner Diameter, 500 Pieces Pack ER0066P

Large Stainless Steel Eyelet with Metal Washer for Curtains and Tarps

This 40.5 mm / 1.59 in stainless steel eyelet with metal washer is designed for large reinforced openings in curtains, tarps, truck tarpaulins, tents, awnings, banners, vinyl prints, outdoor gear, leather, bags, luggage, footwear and technical textile surfaces. It is used where ropes, cords, hooks, tensioning accessories or fixing hardware pass through the material.

The large inner diameter makes this eyelet suitable for applications that need a clean and reinforced opening rather than a small cord hole. The stainless steel body is useful when better resistance to standard moisture, rain and everyday humidity is required.

Why the Metal Washer Matters

The metal washer supports the back side of the material and helps distribute the setting pressure around the opening. This is especially important for tarps, tents, awnings, curtains and technical textiles where the eyelet may be pulled, tensioned or loaded during use.

Important: The eyelet, metal washer, hole size, material thickness and setting force must work together. If one of these is not matched correctly, the eyelet may not close evenly, may rotate, or may pull out under load.

Installation Requires Enough Force

This is not a small garment eyelet. Thick tarpaulin, dense curtain fabric, multilayer canvas, stiff technical textile or leather may require more force than a small hand press can provide.

Use a compatible 40 mm / 1.57 in Eyelet Setting Die for installation. If the material hole needs to be prepared before setting, use a 40 mm / 1.57 in Eyelet Punching Die or a suitable hole cutter. For stronger applications, use a manual impact press, lever press, motorized press or professional eyelet setting machine.

A hand-striking setting tool may be used for small quantities or field-type applications when the correct size is available. For consistent production, a stronger press with correct die alignment is usually safer.

Setting Die and Punching Die Are Different Tools

Eyelet installation has two steps. First, the material hole is prepared. Then, the eyelet and metal washer are set into the material with the correct setting die. A punching die prepares the hole; a setting die closes the eyelet. These tools should not be confused.

If the hole is too small, the eyelet may not sit correctly. If the hole is too large, the metal washer may not grip the fabric securely and the eyelet may rotate or pull out under tension. For curtains, tarps, awnings and technical textiles, material thickness must be matched with eyelet height, washer size and press force before production.

When to Choose Stainless Steel

Stainless steel eyelets are suitable when better resistance to standard moisture, rain and everyday humidity is needed. They are commonly selected for curtains, tarps, tents, awnings and technical textile applications where a large, clean and reinforced opening is required.

Important: Stainless steel provides better resistance to standard moisture, but long exposure to sea salt, chlorides or harsh chemicals may still create corrosion risk. For marine, poolside or chemical-contact environments, final suitability should be checked separately.
