Product Description

Expansion bolts with a performance level of 4.6 refer to:

The nominal tensile strength of the expansion bolt material reaches 400 MPa level;

The yield strength ratio of the expansion bolt material is 0.6;

The nominal yield strength of the expansion bolt material reaches 400 × 0.6=240MPa level;

Drilling depth: It is best to be about 5 millimeters deeper than the length of the expansion pipe.

The requirements for the expansion bolt on the ground are of course the harder the better, which also depends on the force situation of the object you need to fix. The stress strength installed in concrete (C13-15) is five times higher than that in bricks.

After correctly installing an M6/8/10/12 expansion bolt in concrete, its ideal maximum static stress is 120/170/320/510 kilograms, respectively.

The expansion screw is composed of components such as a screw and an expansion tube. The tail of the screw is conical, and the inner diameter of the cone is larger than the inner diameter of the expansion tube. When the nut is tightened, the screw moves outward, and the axial movement of the thread causes the conical part to move, thereby forming a large positive pressure on the outer surface of the expansion tube. In addition, the angle of the cone is very small, which causes friction self-locking between the wall, the expansion tube, and the cone, thereby achieving a fixing effect;

The spring washer on the expansion screw is a standard part because its opening is staggered and elastic, so it is called a spring washer. The function of the spring washer is to use the sharp angle of the staggered opening to pierce into the nut and flat washer, preventing the nut from loosening;

A flat washer is also a standard component, and its function is to evenly distribute the pressure of the nut on the connected parts.

Scope of use of expansion screws

Expansion screws have the advantages of small drilling, high tensile force, and being exposed flat after use. If not used, they can be easily removed to keep the wall flat. They are widely used in various decoration occasions.

Frequently Asked Questions

Q1: What does a performance level of 4.6 indicate for expansion bolts?

A performance level of 4.6 means the nominal tensile strength of the material reaches 400 MPa, with a yield strength ratio of 0.6, resulting in a nominal yield strength of 240 MPa.

Q2: What is the recommended drilling depth for installing expansion bolts?

It is ideal to drill the hole about 5 millimeters deeper than the overall length of the expansion pipe to ensure adequate clearance and proper expansion.

Q3: How does the installation surface material affect the performance of expansion bolts?

Harder materials yield much better fixing results. For instance, the stress strength of an expansion bolt installed in concrete (C13-15) is five times higher than when installed in standard brick.

Q4: What are the maximum static stress values for standard M6 to M12 expansion bolts in concrete?

When correctly installed in concrete, the ideal maximum static stress values are approximately 120 kg for M6, 170 kg for M8, 320 kg for M10, and 510 kg for M12.

Q5: What functions do flat washers and spring washers serve in an expansion screw assembly?

The spring washer uses its staggered, elastic design to bite into the nut and flat washer to prevent loosening, while the flat washer ensures that the nut's pressure is distributed evenly across the surface of the connected part.

Q6: What are the main advantages and applications of expansion screws?

Expansion screws offer the benefits of minimal drilling, high tensile resistance, and a flat finish. They are widely used in a variety of decoration and construction scenarios as they can be easily removed to keep walls flat.
