‚ 

¯»¿At‚ ¯»¿Tradersofoz Australia‚ ¯»¿we stock the M4.2x 38mm Stainless Self Drilling Flat Head Screws in 50/300pcs.Self-drillers are also commonly called ¢‚¬ËœTek¢‚¬„¢ screws, a proprietary brand name associated with their unique shape and function.

These Flat Head screws have a point ¢‚¬Å“like a drill bit¢‚¬, these screws create their own hole, and their own thread in one action. This is probably where the confusion with self-tappers comes in ¢‚¬€œ both kinds of screws are technically self-tapping as far as the function of their threads are concerned, but the massive difference is in the function of their points.

Features:

• Self-drillers can be characterised as a fine thread or a coarse thread, self-tappers can¢‚¬„¢t.
• In short, self-tappers can¢‚¬„¢t drill, self-drillers can as well as tap a thread.
• Drill point sizes dictate drilling capacity. Common Tek point sizes are #2, #3, #4 and #5 (Series 500) ¢‚¬€œ 2 and 3 most common, 4 and 5 for going through thicker metal.
