Types of fasteners:Below are summaries of each of these common types of fasteners and a general description of their important characteristics and usage.
1. Anchor Bolt
Anchor bolts are bolts that are designed to secure a building element or component to a concrete slab or poured foundation.
Anchor bolts can be preset when pouring the concrete structure, is being cast, as with the plate used on top of the poured foundation of a house. Or anchors can be attached after the concrete has hardened by a drilling operation to create a channel into which the anchor bolt can be inserted.
2. Blind Bolts
Blind bolts refer to a style of a bolt that enables a fastener to be used in cases where the application does not allow access to either side of the bolt to tighten or tighten the bolt. A simple example of this is the conventional toggle bolt, which is used to secure objects to a wall at a point between the support beams.
Here the part of the bolt that is behind the surface of the drywall is not accessible and therefore the entire assembly process of the toggle bolt must be carried out from the external (visible) side of the wall.
3. Carriage Bolt
Carriage bolts are a form of self-locking bolts that provide a level of security by using a flush-mounted domed head that allows access to remove or loosen these bolts only from the nut side of the bolt.
Underneath the domed head of the carriage bolt, there is a square profile that can be inserted into a corresponding square cut that is slotted in the joining material to ensure self-locking, which means that the bolt can be tightened from the nut side without the need to remove the head with a wrench to hold on.
4. Arbor Bolt
The bolt permanently attaches to the washer and the threading is reversed. The Matter design is for use in saws and other means to harden the auto during use to prevent blades from falling.
5. Double-End Bolt
Double-end bolts are sometimes called stud bolts and without conventional heads have a threaded part at each end of the bolt. One end design to be threaded into a suitable hole that is tapped with a mate and the other end is threaded to support the nut.
The appearance is similar to a threaded rod, but is not traditionally threaded over the entire length of the stud and can be threaded separately at each end.
The eye bolt has a fully closed or partially closed-looped end in place of the conventional bolt head. The loop can in some cases use to lift the object to which the eyebolt is attached. Some eye bolts are not designate for lifting but may use to route wires, cables, or other similar elements to avoid accidental interference.Eyebolts may offer additional capabilities depending on material structure and finish – some are suitable for low-temperature operation while others design to not reflect light and will therefore blend into the background.
7. Hex Bolt
Hex bolts, also known as hexagon head bolts, are a very common form of bolt available in standard dimensional inches and metric sizes.
As the name itself suggests, these bolts have a hexagon-shaped head suitable for tightening with a wrench or socket. Hex bolts can fully thread or show an unread shoulder.
8. Machine Bolt
Machine bolts use to fasten two pieces of material together, and are similar to hex bolts, except that they will not have a chamber point and design with a washer-bearing surface under the head has gone. They are usually available in both hex head and square head options.
9. Penta Head Bolts
Penta-head bolts are an example of a tamper-resistant bolt, which can use in applications where it is desired to reduce the likelihood that a person equipped with standard equipment may loosen or remove the bolt.
With bolt heads in the shape of a pentagon, standard wrench or socket sets will be unable to be used on these bolts.
10. Round head Bolt
Similar to carriage bolts, the round head bolt does not have a square taper under the domed head of the bolt and is typically used to attach to the wood.
The soft nature of the wood allows the bolt to compress against the surface of the wood and grip by friction to prevent the bolt from turning when the nut tightened.
The shoulder bolt, also called a stripper bolt, is a threaded bolt section of a smaller diameter than the shoulder of the bolt (the part of the bolt between the head and the beginning of the threaded part).
Shoulder bolts are useful to act as a shaft or axle that may include a rotating part, such as a bearing or bushing.
