Key Precautions When Using Long Tek Screws and Sharp Point Self-Tapping Screw

When using long screws, especially Tek (drill-point) or sharp-point self-tapping types, specific precautions are needed due to their extended length and structural stress:

1. Match Screw Type to Material Thickness

• Tek screws are suitable for metal applications. Always match the drill point size (e.g., #3 for up to 6mm steel, #5 for 12mm steel) to the thickness of the material.

• Sharp-point self-tapping screws are ideal for wood, thin metal, or plastic, but not suitable for thick steel.

2. Maintain Proper Alignment

• Long screws are prone to bending or misalignment. Always ensure the tool is aligned vertically to avoid breakage or thread damage.

3. Use Pilot Holes if Needed

• For dense or layered materials, even Tek screws may benefit from pilot holes or pre-marked positions to improve accuracy and reduce stress.

• When using sharp-point screws in hardwood, pre-drilling is advised to avoid cracking or over-torqueing.

4. Use Controlled Torque Tools

• Due to increased resistance with long screws, use a torque-controlled driver or impact drill to avoid screw tip damage, stripping, or tool overload.
