FAQ

Product Details

What does 5.0 x 100 mm mean for this Spax screw?

5.0 mm is the thread diameter and 100 mm is the overall screw length. This size is commonly used for stronger timber connections where you need good embedment without using longer screws.

Is this screw partially threaded or fully threaded?

This model features 61 mm partially threaded. The unthreaded portion helps provide a smoother grip through the first material, while the threaded section improves pull in and holding power in the second.

Which drive type does this screw use?

The screw uses a TS20 drive, designed for a secure fit when using the correct bit. The drive is T Star Torx, so make sure you use the correct driver bit to reduce cam out and wear.

Will the countersunk head sit flush in timber?

Yes, it has a countersunk head intended to sit flush when paired with the right hole preparation. For best results, drill a suitable pilot and ensure the head seats cleanly.

How many screws are included in the pack?

This product comes as a 200 pack, which is convenient for larger jobs and workshop use. Buying in a bulk pack can be cost effective if you are working through multiple timber sections or repeating the same specification.

Is this screw suitable for interior and damp areas?

It is designed with corrosion resistant performance, making it a practical choice for many typical workshop and site applications. For outdoor or high moisture exposure, always check the project requirements and any local material guidance.

What material is it and what should I consider when fixing into timber?

These screws are made from steel and are intended for timber fixing. To achieve a solid joint, use the correct pilot hole size, and match the screw length to the thickness of the boards you are joining.
