Question 2

What are the main specifications I should know about this screw?

Accepted Answer

Key specs: diameter M3.5, length 70 mm, material zinc-plated steel, finish zinc plating for corrosion resistance, and a screwdriver-friendly head designed for easy tightening.

Question 3

What materials can I use this screw with, and what applications is it best suited for?

Accepted Answer

This screw is designed to securely fasten components in wood, plastic, and metal. It’s well-suited for light- to medium-duty assemblies such as frames, furniture, and home improvement projects like shed construction.

Question 4

How do I install the M3.5 x 70mm screw properly?

Accepted Answer

Steps: 1) align the parts you’re fastening, 2) if needed, pre-drill a pilot hole appropriate for the material, 3) insert the screw and begin tightening with a standard screwdriver, 4) tighten gradually and evenly, stopping before over-tightening to avoid stripping or damage.

Question 5

How should I choose the right length and size for my project?

Accepted Answer

Length should allow enough engagement with the base material without risking protrusion. For typical frames or thicker materials, 70 mm provides deeper engagement; for thinner parts, a shorter length may be preferable. Ensure the thread length matches the material thickness being joined.

Question 6

Is this screw suitable for outdoor or high-corrosion environments?

Accepted Answer

The zinc-plated steel offers basic corrosion resistance suitable for general use. For harsh outdoor or highly corrosive environments, consider stainless variants or protective finishes designed for outdoor exposure.

Question 8

Can I reuse this screw after removing it, and are there any care tips?

Accepted Answer

Yes, if the threads remain undamaged and the screw isn’t stripped, you can reuse it. Inspect the threads for wear and clean any debris before reinserting. Use the appropriate screwdriver bit to avoid cam-out and damaged heads.

Question 9

What drive type does this screw use and how do I choose the right driver?

Accepted Answer

The screw is designed for use with a standard screwdriver. Use the corresponding bit that matches the head on your specific screw variant (e.g., slotted or Phillips as applicable) to ensure solid engagement and prevent stripping.

Question 10

What affects the holding strength of this screw and how can I maximize it?

Accepted Answer

Holding strength depends on material type, hole pilot accuracy, and proper tightening. Use a pilot hole for harder materials, engage the full length into the base material, and avoid over-tightening to prevent stripping or material damage. Pairing with appropriate washers or nuts where needed can also improve load distribution.
