Structural Characteristics

The structure of the High strength6 lobe countersunk tapping screws consists of four key components: the head, the driving groove, the drill tail, and the thread. Each component has a specific function.

Flat Head

Geometric shape: The head is conical, with a cone angle of 82° or 90°. The top surface is flat, and the conical surface is smooth without any burrs.

Head size: The diameter of the head is approximately 1.8–2.2 times the nominal diameter of the thread, and the height of the head is approximately 0.5–0.6 times.

Function: After tightening, the head of the High strength6 lobe countersunk tapping screws is flush with the surface of the workpiece, without protruding. It is suitable for occasions that require a smooth appearance. The conical surface fits with the blind hole, creating a self-locking effect to prevent loosening.

6‑Lobe / Torx

Geometric shape: The groove is in the form of a six-petaled flower, with a flat bottom.

Function: The head forms multi-sided line contact with the slot wall and can withstand high torque. It is suitable for use with impact wrenches or automatic tightening equipment, and performs stably in high-speed and high-torque assembly operations.

Self‑Drilling Point

Geometric shape: The tail is in the shape of a drill bit, with a cutting edge and chip-removing grooves.

Function: During installation, the drill tail first contacts the workpiece, then cuts out the hole under the action of rotation and axial pressure. There is no need to drill a hole beforehand. The hardness of the drill tail has been specially heat-treated to ensure it can penetrate steel plates with a thickness ranging from 0.5 to 6 mm.

Thread

Form: Self-drilling and self-tapping thread, with a wide pitch, deep tooth profile, and sharp tooth tip. Usually a full thread.

Function: After drilling the tail hole, the thread immediately follows and a matching internal thread is drilled on the hole wall.

Price advantage

Overall, High strength6 lobe countersunk tapping screws are more cost-effective than "ordinary screws + pre-drilled holes".

One process was omitted, thus reducing the labor cost by half.

Standard procedure: Workers first use an electric drill to make the hole, which takes approximately 5-8 seconds. Then they switch to a screwdriver to tighten it, which takes about 3-5 seconds.

High strength6 lobe countersunk tapping screws: Simply turn it, and it will be done in 5-6 seconds.

Not only was the efficiency improved within the limited working time, but also the labor costs were saved.

There's no need to buy a drill bit.

Ordinary self-drilling screws need to be paired with a drill bit to be used. During use, the drill bit may wear out or break, so additional drill bits need to be prepared.

The High strength6 lobe countersunk tapping screws come with their own drill tips, so no additional drill bits need to be purchased.

The head-down design eliminates the need for hole drilling.

The 6-lobe self-drilling screws are tightened directly to the desired level, eliminating the need for this step and saving money.
