The 8.8 bolt is a high strength bolt and has a grade of 8.8

What does 8.8 mean on a bolt:

The notation “8.8” on a bolt refers to its grade or strength. In the metric system, like in many European countries, bolts are graded based on their material composition and tensile strength.

Here’s what each part of “8.8” represents:

The First Number (8): This indicates the ultimate tensile strength of the bolt material in megapascals (MPa). In this case, “8” means the bolt material has a tensile strength of 800 MPa.

The Second Number (8): This number represents the yield strength of the bolt material as a percentage of the ultimate tensile strength. In the case of “8.8,” the bolt has a yield strength that is 80% of its ultimate tensile strength.

So, a bolt with the marking “8.8” has a tensile strength of 800 MPa and a yield strength of 80% of that, which is 640 MPa. This grade of bolt is commonly used in various mechanical and structural applications where a moderate level of strength is required.

Other names: bolt class 8.8, class 8.8 bolt, bolt 8.8 strength, 8.8 bolt, 8.8 bolt strength, 8.8 hex bolt, heavy hex bolts

2. Hexagon socket head cap screws

A Hexagon Socket Head Cap Screw, often referred to simply as a Socket Cap Screw or Allen Bolt, is a type of threaded fastener with a cylindrical head and an internal hexagonal drive socket (hex key or Allen wrench) in its head for tightening and loosening. These screws are designed to be driven with an Allen wrench or hex key, which fits into the socket in the screw head.

Here are the key characteristics of a Hexagon Socket Head Cap Screw:

Head Shape: The head of the screw is typically cylindrical with a flat top. It has a hexagonal socket in the center.
Drive Type: It uses an internal hexagonal drive, which requires a corresponding Allen wrench or hex key to install or remove.
Thread Type: These screws have straight, uniform threads that run the entire length of the screw.
Threaded Length: The threaded portion of the screw extends from the tip to a certain length, while the unthreaded portion is called the shank.
Applications: They are commonly used in applications where a low-profile fastener is required, such as in machinery, automotive, electronics, and construction. They are also used in precision equipment where access is limited.

Hexagon Socket Head Cap Screws are known for their reliability, ease of use, and the flush, clean appearance they provide when installed. The internal hexagonal drive socket allows for high torque transmission without the risk of stripping the screw head, making them a preferred choice for applications requiring precision and a clean finish.

Other names: socket head cap screws, hexagon socket screw, hexagon socket, hexagon socket bolt, hex socket head screw, hexagon socket head screw, hex socket cap screw

3. Square Neck Bolt

A square neck bolt, also known as a carriage bolt or coach bolt, is a type of threaded fastener that features a square-shaped portion just beneath the head of the bolt. This square neck, or carriage, prevents the bolt from turning when it’s tightened or loosened, making it especially useful in applications where one side of the connection should remain stationary while the other side is being tightened.

Here are the key characteristics of a square neck bolt:

Head: The head of a square neck bolt is typically round or domed, and it may have various drive types, such as slotted, Phillips, or hex.
Square Neck: The square neck is a portion of the bolt, just below the head, with a square cross-section. This square neck prevents the bolt from spinning within the hole or slot it’s inserted into.
Threaded Shaft: The rest of the bolt features a threaded shaft, which allows it to be inserted into a pre-drilled hole or slot and tightened with a nut on the opposite side.
Applications: Carriage bolts are commonly used in wood-to-wood or metal-to-wood connections. They are frequently used in construction, woodworking, and furniture assembly. The square neck prevents the bolt from turning, allowing for a more secure and stable connection.

To install a square neck bolt, you typically insert it through a pre-drilled hole or slot in one of the materials you’re connecting. Then, you secure it by placing a nut on the threaded end of the bolt and tightening it. As you tighten the nut, the square neck prevents the bolt from spinning, ensuring a secure and stable connection.

Other names: round head square neck bolt, carriage bolt, coach bolt

4. Eye Bolts

An eye bolt is a type of fastener that has a threaded shank with a circular at one end. The eye is typically a closed loop or ring, and it is used for attaching or securing various objects to a surface or structure. The other end of the eye bolt has threads that allow it to be screwed into a pre-drilled hole or threaded opening, providing a secure anchor point.

Eye bolts come in various sizes and materials, including steel, stainless steel, and other metals, as well as synthetic materials like nylon.

Eye Bolts are often used in applications where lifting, rigging, or securing heavy loads or equipment is required. For example, eye bolts can be used to attach cables or ropes for hoisting objects, securing cargo on a truck or trailer, or anchoring items to walls or ceilings.

The choice of eye bolt size and material depends on the specific application and the load-bearing requirements. It’s essential to ensure that the eye bolt is properly installed and that it can handle the intended load to maintain safety and prevent accidents.

Other names: lifting eye bolt, eye bolt for lifting, lifting bolt eye, bolt on lifting eye, eye bolt lifting
