Hook bolts are curved steel fasteners used for hanging things from walls and ceilings. They are made of hardened stainless steel and have an open end for easy removal. They require drilling a pilot hole and can be bolted to wooden dowels for added stability. Weight capacity limits are listed on packaging and dividing weight between multiple hooks can reduce failure. Hook bolts have many indoor and outdoor applications and can be removed and reinstalled with little damage to walls. They can also be used as pulleys to increase floor space.

A hook bolt is a curved steel fastener that resembles the top of a question mark. The long, straight section of a hook bolt is usually threaded and may come with one or two nuts screwed on. Hook bolts are a type of anchor bolt commonly used for hanging things from ceilings and walls. Most hook bolts are made of hardened stainless steel so they can handle heavy weights without bending or breaking. Standard hook bolts have an open end for quick and easy removal and reattachment of items.

The straight, threaded end on a hook bolt is flat and does not taper like the end of a hook bolt. Installing a hook bolt usually requires drilling a pilot hole. Hook fasteners are routinely bolted to wooden dowels behind drywall on a wall or ceiling for added stability. Standard and lock washers are commonly applied to the joint between a hanger bolt and a wall to prevent the bolt from loosening due to weight and vibration. Some hanger bolts are designed to screw into bolt anchors that expand into the wall to lock the hanger in place.

Most manufacturers list the weight capacity limits on the hook bolt packaging. Generally the thicker the diameter of the hook, the more weight it can support. The chance of failure and damage can be greatly reduced by dividing the weight of a heavy suspended object between a few different fastening hooks. Bridging the gap between heavy hanging items and hooks with strong springs reduces direct impact on the fastener for added strength and safety. Hanging chairs often come complete with mounting hardware that includes hooks, bolts, and heavy gauge springs.

Installing a few well-placed hook bolts can open up new storage and decorating possibilities in a home or business. A hook bolt is the fastener for attaching hanging plants and hanging art. The affordable and versatile hook bolt has thousands of indoor and outdoor applications. Most hook bolts can be removed and reinstalled in another location in minutes with very little damage to your walls. Floor space in a busy room can be increased by bolting hook bolts into a ceiling to function as pulleys so that occasional-use items such as bicycles and out-of-season clothing can be tied to a rope and lifted up and out of the way.
