Machine Screw, Countersunk Head, 6-Lobe/Machine, Hafren Fasteners

Product Details

Which driver bit do I need for the TS20 feature?

This machine screw uses a TS20 Torx style recess, so you will need the correct TS20 compatible bit for installation and removal. The order reference for this product notes that a special bit is required and should be ordered separately.

Is this suitable for countersunk applications?

Yes. The screw has a countersunk head, designed to sit flush or near flush in materials that have the matching countersink profile. This helps create a tidier finish, especially in assemblies where protruding heads can interfere.

What size and thread specification should I expect?

You can expect the size to be M4 x 10 mm with a fully threaded design. The M4 refers to the thread size, while 10 mm is the screw length. This is commonly used for light to medium fastening tasks where a consistent thread engagement is needed.

Is this screw fully threaded along its length?

Yes, it is fully threaded. That means the thread runs along the majority of the screw length, which can improve grip in certain material types and helps reduce looseness compared with partial thread designs.

Will the stainless steel finish stand up to moisture or corrosion?

The screw is made from stainless steel, which is generally a good choice for environments where corrosion resistance matters, such as damp areas or projects exposed to humidity. For best results, still consider the specific conditions your application will face.

How many screws are included in the pack?

This product is supplied as a 100 pack, making it convenient if you are stocking up for repeat projects, workshops, or scheduled maintenance where you need consistent fasteners.

What kind of parts is this commonly used for?

Machine screws like this are typically used when you need a controlled thread fit into a tapped component or mating thread, often in assemblies where a flush countersunk head is preferred. If your application needs a TS20 drive and M4 x 10 mm length, this should match those requirements.
