Your cart is empty.Hex washer head self drilling screws are designed with a drill point at the tip to pre-drill the screw hole as you go with a “thrilling-like” action (threading or drilling) to eliminate separate drilling, tapping, and installation actions. The length of the drill determines the material thickness which the screw can reliably penetrate. They are ideal use for wood, metal or other tough materials and known for their effecient application performance and endurance. You could see them around because they are widely used in a variety of industries such as construction, manufacturing, engineering, assembling and so on. The 410 stainless steel provide perfect strength and good corrosion resistance in bad environments like high temperature, cold weather and high humidity areas without the need for time consuming and costly maintenance.

Just measure them and if they're the right size just order them.

I used these to drill nickel coated fence posts. I bought 250, not a single one failed. When buying self tappers quality is important, highly recommend this product.

I have an aluminum patio and these worked great for hanging fans, and were less than half the cost of big box stores.

Strips very easily with little holding power. The drill diameter is too big leaving little for the threads to bite in thin metals.Drill dia: 0.211"Thread dia: 0.241"Screw shank dia: 0.170"Otherwise nice quality screw rendered useless.

These are great screws for sheet metal. I just wish I could find the same type on Amazon for wood. The tip is a tad wide and the threads do not get enough grip due to the drill part drilling too big a hole. If you use them in wood they will pull out easier than in sheet metal. But then again, they're not made for wood. But even in sheet metal I should think the auger tip should be slightly smaller than the threads. That would allow the threads to get a better grip. They do work well in 1/8" steel.
