Loosening Fasteners - discrete Techniques For Stubborn Nuts and Bolts

Fasteners can give you fits sometimes. Normally they stay tight and in place until you want to remove them. Sometimes they come loose because of vibration. And, sometimes you want them to come loose and they just won't budge. That becomes a problem because a frosty nut or bolt can sheer off, round off or break your tools.

There are any ways to loosen a nut or bolt when it just doesn't want to cooperate. Depending on the situation, you might want to try all of these to get that piece of hardware to move in the direction you want.

Fasteners Staples Tool Heavy Duty

Before we begin, let's review the very basics; it's right (clockwise) to tighten, and left (counter-clockwise) to loosen, unless it's a left-handed thread. Look for an "L" on the top of the stud or bolt to identify left-handed threads.

The methods below are applicable to nuts and bolts used in metal and plastic applications, and not nails, screws or staples used in wood. Also, keep in mind that it may be critical to work both ends of the fastener with a tool to hold it in place or turn it.

Here are the techniques in the order that I would apply them:

Apply penetrating oil to the association that is frosty or rusted in place. Tap sharply on the nut or bolt with a hammer, taking care not to damage the nut or bolt head. Tighten a bit at first and then loosen. Use an impact wrench - electric, pneumatic or manual. Heat the fitting with a torch (if there is no danger of fire or damaging other material). Whack the far end of your wrench with a mallet to act as an impact wrench. Use a longer wrench or apply a "cheater bar" to get better leverage. Cut the fasteners out and install new ones.

If your efforts succeed in a rounded over nut or bolt, use a pair of vise grips to get a grip.

Note: when using a torch to heat up a fitting, make inescapable there are no flammable materials anywhere nearby. If you have fuel nearby, move it far away and upwind. Also, use a torch only with sufficient ventilation and make inescapable it doesn't burn material adjacent to where you're working. Check twice for fire, explosion and burn hazards, because it too late once it happens.
