Cut-off Self-tapping Screw

 

Cut-off self-tapping screws, also known as break-off self-tapping screws.

Features:

1. Cut-off Design: The end of the screw features a V-shaped or annular breakout groove. During installation, the end automatically breaks off when the set torque is reached, ensuring precise control of the tightening force.

2. Self-tapping Capability: The threads are made of high-hardness carbon steel or stainless steel, and the tapered guide structure at the front allows internal threads to be cut directly into the substrate without pre-drilling.

3. Drive Types: Available in various drive types, including Phillips (PH2), Pozidriv (PZ2), and slotted, they are perfectly compatible with common electric screwdrivers and screwdriver bits.

Applications

1. Home renovation, such as fastening paneling and ceiling tiles.
2. Wooden furniture manufacturing, such as fastening wooden panels and connecting bed frames.
3. Some rustic and retro-style interior designs can be enhanced with flat-head self-tapping screws of varying sizes and lengths, adding a unique touch to these designs and enhancing the inherent beauty of the interior space.

Why choose our Cut-off self-tapping screws?

1. No pre-drilling pilot holes are required; drilling and tightening are completed in one step, increasing installation efficiency by over 50%.

2. The superior self-tapping design creates a tighter thread engagement, with significantly higher pull-out and shear strength than ordinary wood screws.

3. The sharp drill tip cleanly cuts through material fibers rather than spreading them apart, significantly reducing the risk of splitting in wood, especially hardwood and composite materials.
