Bolts and nuts stretch every time they are torqued and stay stretched. That is why many manufactures suggest to replace bolts and nuts so they eventually won't break. Why take chances of being stranded because of fatigued (failed) bolts or nuts.

- If the joint is fixed using a nut and bolt then assuming the nut is selected from the same grade as the bolt there is little need to size the nut. The fastener manufacture sizes the length of the nut to ensure the screw will fail before the nut. If the screw fastens into a tapped hole then a check of the depth of thread engagement is required.
- This works well but should be used as a last resort as you risk damaging your wheels and if you get it wrong you may well be left with a locking wheel bolt or nut that can only ever be drilled or ground out - a very, very expensive mistake!
Every shop owns one and you should too. Just find the “leaf” that mates to the threads on the nut or bolt and read the screw “pitch” (for metric fasteners) or the teeth per inch (TPI) for English fasteners. Record the number and run to the hardware store, or use the measurement to match up an old bolt from your collection.
- Although I've seen 3/8" bolts and washers, I don't believe that I'd use them. 1/2" bolt with 1/2" x 1" washer 8" long with a 5/8" hole are pretty much the standard combo. Can't imagine using "j" bolts without washers, if nothing else to hold the sill seal down tight. The architect's plan should have shown this in one of his typicals (inset).
As with other varieties of pliers, locking pliers should be used rarely, if at all, on nuts, bolt heads, pipes, or fittings that are to be reused. The serrated teeth on most locking pliers can...
- rotation, tighten the jamb nut until it seats using the 3/4 inch box wrench. Once the jam nut is seated, con-tinue tightening the nut an additional 1/8 turn (most people do not have access to the special tools needed to torque the jam nut while holding the force screw from turning, so the fore mentioned procedure will achieve an adequate result).
Jul 13, 2013 · They aren't nuts anymore, just blobs of rusted metal. I decided to cut them along the length of the stud with an angle grinder or a Dremel tool with a reinforced cutting wheel.Then I turned the weakened nuts off with a channel lock pliers or found a socket that would fit. On one of them I used a hammer and chisel to get the reduced nut off.
- Carriage bolt: Image credit: Bolts 'n Nuts Plus. Carriage bolts are used to fasten metal to wood. The undercut of the bolt head is square to hold the bolt in place once tightened. Elevator bolt: Image credit: TOPS Inc. A flat, plain or countersunk head with a squared undercut holds the bolt in place when a nut is tightened.
In presswork, dies are used in pairs. The smaller die, or punch, fits inside the larger die, called the matrix or, simply, the die . To cut an outside thread, the die is lubricated with oil and simply screwed onto an unthreaded bolt or piece of pipe, the same way a nut is screwed onto a bolt.
- Heaving on a pair of pliers to tighten a wing nut is probably more of a threat to the threads than tightening with a proper wrench. Also, due to the potential for slipping, using pliers on a wing nut is probably far more likely to result in damage than using a proper wrench on a hex nut. Because a hex nut is symmetrical and a wing nut is not, a wing nut is far more prone to be loosened by vibration than a hex nut.
Pliers can tackle a variety of jobs including installing and shaping wire, tightening and loosening nuts and bolts, removing nails and a host of other functions. Not all pliers are designed for electrical work. Make sure the handles are insulated to protect from electrical shock if you use them on or around wires.
