Product Description

The following is an introduction to the mechanical properties and installation parameters of the Hexagon Flange Self Tapping Concrete Anchor Bolt from China Xiaoguo®.

1.Recommended installation parameters

Nominal diameter	Drill bit diameter (mm)	Drilling depth (mm)	Minimum substrate thickness (mm)	Minimum clearance (mm)	Minimum spacing (mm)	Installation torque (N·m)
M6	6.0	45	80	45	60	8-12
M8	8.0	55	90	50	70	15-20
M10	10.0	70	110	60	85	30-40
M12	12.0	90	140	75	100	50-65
M16	16.0	115	180	95	130	90-110

Hexagon Flange Self Tapping Concrete Anchor Bolt

Drilling method: Utilize a hammer drill in conjunction with a hard alloy drill bit.

Cleaning requirements: Use an air pump or vacuum cleaner to blow at least 4 times. There should be no visible dust inside the hole.

Installation tools: Impact wrench or torque wrench, with a hexagonal socket.

2.Installation torque and tightening requirements

The installation torque should be kept within the recommended range.Insufficient torque will lead to inadequate anchoring; excessive torque may cause thread slippage or local damage to the concrete.

After installation, the bottom surface of the flange head should be in close contact with the fixed component, and the Hexagon Flange Self Tapping Concrete Anchor Bolt should not be turned by hand.

3.Environmental and temperature limitations

Applicable environmental temperature: Carbon steel, electro-galvanized coating: -40°C to +80°C

Stainless steel can withstand slightly higher temperatures up to ≤ 120°C.

Common Errors and Solutions

The following are the 4 most common mistakes that are most likely to occur when installing Hexagon Flange Self Tapping Concrete Anchor Bolt , along with the corresponding solutions.

1.The diameter of the drill bit is incorrect.

Performance: A drill bit 1-2 mm larger in diameter than the anchor bolt was used. After the anchor bolt was screwed in, it loosened.

Reason: The hole is too large, and the thread cannot reach the inner wall of the hole, resulting in no effective engagement.

Correct approach: Use a drill bit with the same nominal diameter as the anchor bolt.

2.Insufficient hole cleaning or incomplete hole cleaning

Performance: The resistance varies greatly when拧ting in.

Reason: Dust accumulates inside the hole, preventing the thread from engaging.

The correct procedure: After drilling, blow air at least 4 times until the blown air is free of obvious dust. Alternatively, you can use a vacuum cleaner.

3.The drilling depth is insufficient.

Performance: The anchor bolt has been fully tightened, but the flange has not yet come into contact with the fixed component.

Reason: Insufficient hole depth.

The correct approach: The depth of the hole should be 5-10 mm greater than the effective embedment depth of the anchor bolt.

4.Tilt when tightening

Performance: The Hexagon Flange Self Tapping Concrete Anchor Bolt becomes skewed after being screwed in.

Reason: The drill bit is not perpendicular, or the angle of the wrench used during insertion is incorrect.

The correct approach: Keep the electric drill perpendicular to the substrate during drilling; initially, hold the anchor bolt in place with your hand when screwing it in.
