Working principle

The working principle of Hex Flange Head Self Cutting Concrete Anchor Bolt is based on metal cutting and mechanical locking, rather than expansion friction.

（1）Drilling preparation

Drill holes of the specified diameter and depth onto the concrete substrate.After drilling, the hole must be thoroughly cleaned using an air pump or a vacuum cleaner to ensure that there are no floating dust particles on the hole wall.

（2）Thread self-cutting

Insert the anchor bolt into the hole and apply force with an impact wrench or socket wrench to screw it into the hole.The self-cutting threads with surface hardening come into contact with the inner wall of the hole. During rotation, the cutting edges of the threads will slightly cut off the concrete on the inner wall, forming a spiral groove that matches the threads of the Hex Flange Head Self Cutting Concrete Anchor Bolt.

（3）Anchor locking mechanism

When the anchor bolt has been screwed in to the predetermined depth, stop screwing. The threaded part of the anchor bolt is fully embedded in the threaded groove cut into the base material, creating a mechanical interlock.

Selection of materials and adaptation to the environment

When choosing the material for Hex Flange Head Self Cutting Concrete Anchor Bolt, the key factors to consider are: whether it is for indoor or outdoor use, and whether it will come into contact with water or chemicals.

1.Indoor dry environment

Carbon steel + Electro-galvanizing (blue-white zinc)

For example：Factory equipment is fixed, there are warehouse shelves and indoor railings.

2.Indoor dampness or presence of condensation water

Carbon steel + yellow zinc or mechanical galvanization

For example：Car washing equipment, refrigerated storage shelves.

3.Ordinary outdoor (subject to rain, not near the coast)

Two options:

Dakro: Cheaper version, with salt spray resistance of over 1000 hours, suitable for outdoor use, it will last for 10-15 years without any problem. The appearance is grayish-black.

Stainless Steel A2: Looks nice, but it's 2-3 times more expensive. If the project budget permits, simply choose stainless steel.

For example：Outdoor billboards, street lamp bases, park benches, fence posts.
