Advantages of M24 wedge anchor expansion bolts and precautions during use

Advantages of M24 wedge anchor thru bolts

High reliability
Applicable to cracked concrete (certified models), good seismic performance, strong long-term stability.

Wide adaptability
Can be used for hard substrates such as concrete (C20 and above strength), natural stone, etc.

Some models support installation at close margins and narrow spacing (must comply with specifications).

Removability

Compared with chemical anchors, it can be removed and reinstalled (expansion sleeves need to be replaced).

Economical

The unit price is lower than that of chemical anchors, and no maintenance time is required, and the construction efficiency is high.

m24 wedge anchor install precautions for use

Substrate requirements

Concrete strength must be ≥C20, avoid steel bars or pre-buried pipelines.

Avoid using in loose substrates such as hollow bricks and lightweight blocks.

Drilling specifications

The drilling diameter must match the expansion bolt specifications (such as M24 usually requires a 28mm drill bit, refer to the manufacturer’s instructions for details).

The hole depth should be greater than the length of the expansion sleeve (usually 4-5 times the bolt diameter), and the dust in the hole should be thoroughly cleaned.

m24 wedge anchor install steps

Insert the expansion bolt into the hole and ensure that the sleeve is fully inserted.

Use a torque wrench when tightening the nut, and apply the torque in stages to the specified value (avoid over-tightening to cause slipping or cracking of the substrate).

Load and spacing

Dynamic loads (such as vibrating equipment) need to reduce the design load by 20-30%.

Minimum margin ≥ 5 times the anchor diameter, spacing ≥ 10 times the diameter (specific adjustment according to the specification).

Environmental restrictions

Avoid long-term exposure to humid or corrosive environments (optional stainless steel).

Heat-resistant models (such as nickel plating or special coatings) should be selected for high-temperature environments.

m24 wedge anchor test Quality inspection

Perform a pull-out test (non-destructive test) after installation to ensure that the design load is reached.

Check whether the nut is loose and tighten it again if necessary.
