Flat Head Screws

Flat Head Screws

Have AQuestion

Flat Head Screws, also called Countersunk Screws, are conical with a flat outer face and a tapering inner face. An advantage to this type of screw is that very little of the head protrudes beyond the surface, allowing it to sink into the material. These screws are commonly made out of stainless steel or zinc coating.

These screws are typically used in applications where the fastener protruding above the surface is unacceptable.

Need help determining screw length? Flat head screw length is measured from the top of the head to the end of the screw.

March 7, 2016, 4:06pm Let me put it this way: January started my 37th year in this business, (I’ll be 55 in June, so I started when I got out of high school). Nobody ever calls when you go over and above and get them out of a bind. You can fill 99 out of 100 items, and they will call and bitch about that one item. Very seldom do they let you know how you got them out of a bind., or did the extra for them, or stayed late or delivered stuff on the weekends, etc. They have come to take it for granted, but I suppose we created the monster by the service level we maintain. And service is what we have that the big guys do not. John Wilson, there at U-Bolt It, did a fantastic job for us. I figure the sizes and quantities we were requesting were a little of a shocker, but John was all over it. And we appreciate all that he did. All of these SS U-Bolts were for our nuclear plant here in Mississippi. They went on re-fuel outage a couple of weeks ago, which they do every two years. And when they go on an outage, it is wide open for about a month. Cost doesn’t matter, freight doesn’t matter, get it here, and get it here fast. I’ve been through about 10 of these outages, and they never plan ahead very well. So compliments are in order for John and whoever else there did these for us. U-Bolt It did an exceptional job and we do appreciate it. Anything else comes up like this, you will be the first on the list. Let me add this though…..I’m not totally convinced that John went out in the plant and got his hands dirty….just saying

– M.
