This hook bolt is perfect for mounting and adjusting a garage door spring.
This hook bolt is long enough to provide plenty of adjustability and strong enough to hold spring tension.

Good quality.
Too much money for a plain hook, but saved me the trouble of searching in a hardware store.

Only one bolt
The title says "hook bolts", the description says "total eaches: 10" [sic], but only a single bolt was included. Sad!
