DIN444 Stainless Steel (304/316/410) Eye Bolts with Wing Nuts (Butterfly Nuts)

Compliant with DIN444 standards, these versatile eye bolts (also known as dog bolts) are crafted from premium stainless steel grades—304, 316, and 410—paired with matching wing nuts (butterfly nuts) to deliver secure, convenient fastening for hanging, lifting, and securing tasks across residential, commercial, and industrial settings. The stainless steel construction ensures exceptional durability: 304 grade offers reliable corrosion resistance for indoor and mild outdoor use, 316 excels in saltwater, coastal, or chemical environments, and 410 provides high tensile strength for heavy-duty applications.

Heavy forged eye bolts with a continuous eye may be forged with an integral shoulder, allowing their use for heavy off-axis loads.


Eye bolt with integral wall anchor
Eye bolts are often installed into masonry and so versions that form their own anchor bolt are commonly available. Most of these screw into some form of shield anchor. Some lightweight forms are not screwed, but rely on just the pull on the ring itself to expand the anchor.
