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;
Screw Size: #10 ;
Screw Length: 1/2";
High quality stainless steel 410;
Package Included: 100 PCS ;

Well built and the finish doesn't come off so easily. Screws in tight.

These are exactly as advertised but...I found them when I was really looking for some cosmetic screws for joist hangers and hurricane straps. These are self-tapping for sheet metal, perfect for that but not coarse wood screws that I actually needed.

These screws were used to attach hinges to a 14 ga decorative steel fence post/gate. I needed new screws because a few of the screws supplied with the hinges snapped or stripped. Very satisfied with the screws. Not a five because I would like to use more in a few different applications before granting a higher rating. Although these screws are listed as Self Drilling, my own preference is to drill a pilot hole in any steel greater than16 ga. when using a small #10 Tek screw - which I did. And care should always be taken to drive the screw straight and with enough pressure that the cutting tip can bite adequately. I was satisfied with the performance in my situation - especially considering the fact that finding a black coated #10 SS Tek screw in stock is almost an impossibility at most retail stores.

Used to add bike tire to peg perego gator. Hex drive better than Philips and likely can be removed down the road if need be.

These used to be great, #14 fit 3/8" socket like it should.The last order I got, all three boxes were #14 but now incorrectly fit a 10mm socket.No way to contact seller and found out too late to return.

The finish of the screws is well done and fit drill socket with no issues like others have reported.Where the product fell down for me ... they are not self-drilling into 1/16" steel posts for use on deck installation. The first 4 regardless of speed (tried different speeds) the points shattered/broke.Ended up having to drill each spot with a small pilot hole to install doubling the time -- once they had a pilot hole to use they installed fine BUT that defeats the purpose of self-drilling.
