Bending an eyebolt. . .
. . .is officially a Bad Idea, just like bending any bolt, but if
someone [cough] wanted to have the eyes of a couple eyebolts knocked over about 45 degrees, is heat a good idea? How much attention should be paid to the radius of the curve? These would be small eyebolts, the i.d. of the eye is about 3/8 in. Not much force will be applied in service; it's to attach a small instrument panel to a plastic panel in a motorcycle. Suggestions, jeering etc. are welcome. -- Ted Bennett |

Bending an eyebolt. . .
The hardware store eyebolts (eye is formed from rod and not welded) are
usually hot rolled steel that bends easily without heat. Just stick in the vice and use an adjustable wrench. Of course, they have no strength to begin with so nothing lost. I might add that my local home store had some inexpensive "1/4 inch" (rod diameter) eyebolts. When I got them home and tried to add some additional mounting nuts, it worked out they were 6mm metric. They got them back as "mismarked and misleading" Ted Bennett wrote: . . .is officially a Bad Idea, just like bending any bolt, but if someone [cough] wanted to have the eyes of a couple eyebolts knocked over about 45 degrees, is heat a good idea?

How much attention should be paid to the radius of the curve? V-block below, eye bolt, bar stock sized for the radius you want, and a hydraulic press. Go slow & easy and stay out of the trajectory for when/if it snaps. You'll want to use mild bolts, this isn't a time for something brittle. Dave Hinz |

If they're ordinary mild steel eyebolts, just bend 'em cold. I'd grab the eye in the vise, slip a piece of pipe over the straight part and pull until the desired bend was achieved. A brass hammer, or a steel hammer with a block or drift of brass, aluminum or hardwood would also do it. Heat would burn off the plating and they'd then rust quickly unless replated or painted. The steel bolt will still be considerably stronger than the plastic panel to which it will be attached. |

Sounds to me like what he really wants are ring-bolts, or tie-down
bolts.

Saw the eye open. It is less stressful on the bolt and you might get away
with it if you are careful. Bending might weaken the entire eye.

I think you misinterpret what Bennett meant; he isn't opening the eye, but instead is tilting its circle at 45 degrees, then bolting through the eye to a panel to support it at desired angle. -jiw |
