What are parts of bolts?
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. Washers are often used to prevent loosening and crushing.
What holds a bolt in place?
Many bolted joints include a thin, flexible gasket between the bolt head and the surface of the joint to seal the joint completely against gas or liquid leaks. The gasket itself acts as a spring, pushing back against the pressure of the bolt and the joint face.
What are the three types of bolts?
The principal types of bolts commonly used include:
- Anchor Bolts.
- Blind Bolts.
- Carriage Bolts.
- Double End Bolts.
- Eye Bolts.
- Flange Bolts.
- Hex Bolts.
- Machine Bolts and Machine Screws.
What is B8M stud?
ASTM A193 Grade B8M is a standard material specification for corrosion resistant 316 stainless steel fasteners such as bolts, screws, studs, threaded rods and other externally threaded parts, for use in high tensile, high temperature and special purpose applications such as pressure piping & pressure vessels bolting.
What are the 4 parts of a bolt?
An Introduction to the Parts of a Bolt
- Head. The head is the uppermost part of a bolt. It serves as the gripping surface for tools.
- Shank. Below the head is the shank. The shank is the smooth part of a bolt that’s devoid of threading.
- Threading. All bolts have threading.
What are bolt types?
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.
Can you use bolts without nuts?
However, bolts can also be screwed into a threaded hole in order to fasten something down without the need for a nut, like a valve cover bolt that fastens down the valve cover to the rest of a car’s engine.
What are the most commonly used bolts?
Some of the most popular bolts and their applications include:
- The carriage bolt. A carriage bolt has a round, smooth head that has no slots in it, so you don’t get to tighten it using a screwdriver or wrench.
- The stove bolt.
- The machine bolt.
- The all thread.
- The J bolt.
What is the difference between B8 and B8M?
These bolts have similar strength requirements but differ in their corrosion resistance. Grade B8 bolts are made from type 304 stainless steel, while Grade B8M bolts are made from a more corrosion-resistant type 316 stainless steel.
