Eye Screw

The eye screw is a specific type of installation fastener widely used in construction. Structurally, it consists of a metal rod, one end of which is fitted with a metric thread, while the other end is fitted with a loop (eye) for attaching various structures. The threaded part is installed into a wall or ceiling/floor slab, for which a plastic wall plug or anchor may additionally be used. Screws of this type are selected based on dimensions and operating conditions.

Fastener application features

The threaded part of the screw can be installed into a pre-made hole in wood, concrete, brick and other construction materials. Concrete and brick walls require the prior installation of an anchor or polymer wall plug: the thread is screwed into it, which ensures secure fixation in the material. An anchor is particularly reliable, as it acts as a spacer and resists pull-out of the screw even under heavy loads.

An eye screw fastener can have a threaded part diameter from M3 to M10, with a length ranging from 15 to 100 mm. When selecting, the eye diameter must also be taken into account — it can range from 6 to 15 mm in accordance with the standard. A cable, rope or other installation fitting can be passed through the eye to secure various structures. The fastener is used indoors and outdoors; for long-term use, the material must be selected correctly.

Screw materials

The eye screw can be made from the following types of materials:

• St steel without additional protective coatings. This type of fastener is used for installing structures inside dry premises.
• Steel with a zinc coating applied by electrogalvanizing. This significantly increases the corrosion resistance of the metal to external influences. Zinc-plated fasteners can be used for outdoor installation of rigging fittings for various purposes.

The choice of screw depends on the conditions of use. If structures need to be installed in premises with high humidity, temperature fluctuations or a chemically aggressive environment, fasteners with a protective zinc layer are used. The eye screw has greater pull-out resistance than the eye wood screw, thanks to its metric thread — this allows the permissible load to be significantly increased.

Applications of the eye screw

This type of fastener is used in construction and installation work. It provides a strong anchor point for attaching cables, ropes and other rigging fittings when installing various structures. The eye can be used when installing awnings, canopies, setting up various temporary structures, and more. If necessary, the fastener can be reused, as it unscrews easily from the material.

The eye screw is suitable for outdoor use and is notable for its strength and durability. FLOK supplies eye screws in wholesale lots of any volume.
