Common Pitfalls

- Do not confuse with 'проушина' (lug, clevis) which is a broader category.
Common Mistakes
- Misspelling as 'eyebold' or 'eye-bolt' (though hyphenated form is sometimes seen).
- Using it as a verb (e.g., 'eyebolt it to the wall').
- Confusing it with 'eyelet', which is smaller and often for fabric or lace.

FAQ
Frequently Asked Questions
No. A screw eye is typically smaller, has a pointed end, and is screwed directly into wood. An eyebolt usually has a machine thread and is fastened with a nut or into a tapped hole.
No. Only eyebolts specifically rated and marked for lifting ('lifting eyebolts') should be used for overhead lifting. Using a standard hardware store eyebolt for lifting can be extremely dangerous.
The shoulder provides a bearing surface to distribute the load when the eyebolt is installed, preventing it from being pulled into the mounting material and reducing side-load stress.
It is most commonly written as one word ('eyebolt'), though the hyphenated form ('eye-bolt') is also occasionally seen, especially in older technical documents.
