Self Drilling Stainless Steel Screws Flat Head M4.2x32mm 50PCS/300PCS
At Osupply Australia we sell online the M4.2 x 32mm Stainless Self Drilling Flat Head Screws in 50/300pcs.Self-drillers are also commonly called ‘Tek’ screws, a proprietary brand name associated with their unique shape and function.
With a point “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 – 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) – 2 and 3 most common, 4 and 5 for going through thicker metal.
