3. PRYING ACTION • Prying action is a phenomenon (in bolted construction only) whereby the deformation of a fitting under a tensile force increases the tensile force in the bolt. ... It is caused by the prying forces which results in distortion of cap plates beam flanges and bolts.

I have found that iFixit stuff is really high quality for the most part. With any tool, remember that you are buying it to use it, and it has a limited lifespan and is intended for a specific task (i.e. a screw driver is not a pry tool).

There are many types of bolts and hardware nuts. Most, if not all, bolt types have machine threads. A threaded bolt screws into nuts to hold or fasten materials together. Bolt types include eye bolts, wheel bolts and machine bolts while types of nuts include cap nuts, expansion nuts and u-nuts.

Bolts can come in a wide range of different sizes and shapes, but the basic production process generally remains the same. It starts with cold forging steel wire into the right shape, followed by heat treating to improve strength and surface treating to improve durability, before being packed for shipment.

First Stage of Tightening: As a first stage, all bolts in the joint shall be tightened to 'snug tight' condition. Snug tight condition means the nut is tightened using an ordinary wrench by an average worker, applying maximum force on the wrench. This stage is required to bring the plies in close contact.

Bolt cutters are the common tool of choice for to cut padlocks during forcible-entry. ... When a padlock fails or fractures, it usually does so at the latch cut on the shackle, or at the base of the shackle where it swivels down inside.

Also commonly known as lag bolts, lag screws are some of the toughest fasteners. These extremely sturdy fasteners are usually used to connect heavy lumber or other heavy materials that are bearing an intense load. ... Normal wood screws thread as they enter the wood, where lag screws require a hole to be drilled first.

Yes, that bolt is normal thread, counterclockwise loosens it. The engine turns the opposite direction as the bolt removal direction to gaurantee that it won't back out. Consequently, it's ridiculously tight.

Threading and tapping are the operations used to produce screw threads. Threading is an operation in which threads are produced on the outside of a component or we can call them as external threads using a die whereas, tapping is an operation in which internal threads are produced using a tool called tap.

The wheels are turned by friction as the cutting head rotates and hydraulic cylinders push from behind. This thrust is a function of the number and size of the cutting discs. The thrust a TBM can place on a disc goes up with the square of its diameter, according to John Turner, chief engineer at Robbins.

Torque-to-yield (TTY) head bolts are designed to stretch when used. Once stretched, they are not as strong as before. Consequently, they cannot provide the same amount of clamping force and may break or shear off if reused.

A hex key, also known as an Allen key or Allen wrench, is a small handheld tool that's used for for driving bolts and screws with a hexagonal socket. They are available in many different sizes, though they all have the same hexagonal-shaped tip.

A torque to yield fastener (TTY) or stretch bolt is a fastener which is torqued beyond the state of elasticity and therefore undergoes plastic deformation, causing it to become permanently elongated.
