To use your washer and bolt properly, first insert the bolt into the washer. Next, slide the bolt and washer into the mounting hole. Once the bolt is threaded into the hole, begin turning the head of the bolt using the appropriate sized wrench. Tighten the bolt down to the washer until the head contacts the washer.
Why do you use a washer with a bolt?
washer, machine component that is used in conjunction with a screw fastener such as a bolt and nut and that usually serves either to keep the screw from loosening or to distribute the load from the nut or bolt head over a larger area. To prevent loosening, several other types of washers are used.
Which side of bolt does washer go?
If there is only one washer used with a nut/bolt, it usually goes on the nut side. The nut in most circumstances is more movable, and is more commonly turned to tighten the assembly. The washer helps prevent damage to the surface of the object being fastened.
Do you put the washer on before the bolt?
Before a threaded fastener (such as a screw) is driven into a surface, a washer may be placed through the end for greater protection. This prevents the bolt head and nut from scratching or indenting the surfaces of the two fastened parts, which could ultimately loosen the fastener.
Where do you put the washer on a bolt?
Put the washer directly underneath the nut. If you have more than one washer, you can put one next to the head of the bolt and one next to the nut. If you have a washer and a lock washer, put them both next to the nut, but make sure the lock washer is between the regular washer and the nut.
What are Grade 8 bolts used for?
Grade 8 fasteners are considered hi-strength / high-tensile fasteners and are used in many highly industrial applications such as machinery, valves, pumps, vessels, motors, tractors, and even tanks… Although it may seem like a bolt is a bolt, there are significant differences in how each bolt is manufactured.
Which is the nut and which is the bolt?
The bolt consists of a head and a cylindrical body with screw threads along a portion of its length. The nut is the female member of the pair, having internal threads to match those of the bolt.
Should you use a lock washer with a lock nut?
Locking Washers Place the lock washer between the nut and the work surface if using a nut-and-bolt configuration, or between the fastener head and the work surface if using a tapped hole configuration. In other words, the bolt goes straight into the hole and doesn’t poke out the other end, so no nut is used.
Do I need a flat washer with a lock washer?
Should I use a flat washer with a lock washer? – Quora. It’s useless if you do. A lock washer is designed to press into the surface of the nut and whatever is being fastened. Flat washers spread out the load of the tension to prevent pull through or bending whats being fastened, but makes lock washers useless.
Should you tighten the nut or the bolt?
There is no simple answer to this as in some instances, it is perfectly acceptable to tighten the bolt head while holding the nut in place. In other situations, it’s acceptable to tighten the nut.
Does Double nut prevent loosening?
If the thick nut is overtightened, there is the risk of thread stripping or the tensile fracture of the bolt between the two nuts. The reason why the two nut system is effective in resisting self loosening is due to the way the threads are jammed together (hence the term jam nut being frequently used for the thin nut).
Is a Grade 10 bolt stronger than a Grade 8 bolt?
Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher number means the stronger the bolt. For most home and automotive applications, you won’t need anything more than a grade 8 bolt strength or metric class 10.9.
Is Grade 8 the strongest bolt?
The strongest commercial-quality bolt is grade 8, marked by six raised dashes; its medium-carbon alloy steel has been quenched and tempered to achieve a tensile strength of 150,000 psi.
What is stronger Grade 5 or Grade 8 bolts?
Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions.
How do bolts work?
Bolt Threads Turning the bolt causes the threads to move the complementary slot or nut upward against the inclined plane. The greater the torque, or turning force, the greater the pressure pulling the nut forward along the threads.
Why do bolts need a nut?
Bolts are typically used to make a bolted joint by using a nut to apply force while using the shank to act as a dowel. This essentially pins the joint against sideways forces. And because of this, many bolts have an unthreaded shank (known as a grip length); thus, making them more effective for dowels.
What’s better lock nuts or lock washers?
Here is the basic breakdown of when you will want to use a locknut over a lock washer: When you need something that can handle the pressure that comes with torquing down a bolt or screw, choose a lock washer. For those home projects that neither need nor can handle the torque required to tighten it, use a locknut.
