Question 1

What is GI Machine Screw per pkt and what is it used for?

Accepted Answer

GI stands for galvanized iron. These are machine screws with internal threads designed for secure fastening in metal or plastic assemblies and are often used in general purpose machine mounting, construction, and equipment assemblies.

Question 2

What materials and finish are these screws made of?

Accepted Answer

They are made from galvanized iron with a zinc finish, which provides improved corrosion resistance and durability for use in a variety of environments.

Question 3

What head styles are available for GI machine screws?

Accepted Answer

The product line includes various head styles such as slotted, Phillips, and hex heads. The item described here features a Phillips slotted head for strong drive engagement.

Question 4

How do I choose the right length and diameter for my project?

Accepted Answer

Measure the thickness of the parts to join and the depth of the threaded hole or nut. Choose a screw long enough to engage securely, typically 1–2 full threads beyond the material, and select a diameter that matches the tapped hole or nut size you are using.

Question 5

Can I use GI machine screws with nuts or tapped holes?

Accepted Answer

Yes. They are designed to work with nuts or tapped holes to create a strong, reliable connection for metal or plastic components.

Question 6

How should I install these screws for best results?

Accepted Answer

Align the screw with the hole, start by hand to avoid cross-threading, then use the appropriate driver to tighten gradually. Avoid sudden over-tightening and use a torque-appropriate driver to prevent stripping.

Question 7

Are these screws suitable for outdoor or high corrosion environments?

Accepted Answer

The galvanized zinc finish provides good corrosion resistance for many applications, but for extreme outdoor exposure or highly corrosive environments you may want to consider additional protective finishes or stainless steel options.

Question 8

What are some common use cases for GI machine screws?

Accepted Answer

They are widely used for mounting machinery components, securing electrical assemblies, joining metal or plastic parts in industrial and automotive contexts, and other general fastening tasks where threaded connections are needed.

Question 9

How do GI machine screws compare to zinc plated slotted machine screws?

Accepted Answer

GI machine screws with galvanization typically offer superior corrosion resistance compared to standard zinc plated options, which can be advantageous in damp or outdoor environments. If you need extra protection against rust, GI is often the better choice.
