PRODUCT USER GUIDE: Choosing plastic screws

To help you choose the right plastic screws, ajile, specialist in plastic hardware and plastic fasteners, shares its advice in this product user guide.

Choosing the right screw for your project

The choice of a screw first and foremost depends on your project. Many screws are designed for specific uses such as wood screws, drywall screws, metal screws and many others. On the ajile online store, you will only find plastic screws. These nylon screws offer specific advantages compared to metal screws: light weight, electrical insulation, resistance to corrosion and chemical agents.
Nylon screws are therefore suitable for model making, electrical installations, plumbing, marine environments such as boats, outdoor use, or installations exposed to chemical products.

Choosing the right dimensions for a suitable screw

The diameter, length and pitch of the screw are very important criteria to consider.
For length, a small screw should be three times the thickness of the fixing support to ensure proper holding.
The diameter of a screw also ensures good strength. Its diameter corresponds to its metric thread.

Selecting the right screw head

Finally, the screw head is also a key criterion that should not be overlooked when choosing screws.
- Countersunk head screws are ideal for a flush fit in the support.
- Hexagon head screws provide a higher tightening torque and are fastened using a wrench.
- Round head screws are the most versatile and are used to fasten simple materials. They provide a large contact surface.
- Knurled head screws offer better grip for tightening and therefore improved holding strength.
- Headless screws are set screws used to join two parts together.
All nylon screws are available from the ajile online hardware store. Browse our wide range of plastic screws and order the exact quantities you need.
