## Description

Machine screws are often used with nuts but also often driven into tapped holes (without nuts). They might be considered a screw or a bolt based on the Machinery's Handbook distinction. In practice, they tend to be mostly available in smaller sizes and the smaller sizes are referred to as screws or less ambiguously as machine screws, although some kinds of machine screw can be referred to as stove bolts. A flat head is A head with flat top and a conical bearing surface (bottom). Designed to be Countersunk. Rod with spiral threads the entire length and with one flat end and a head on other end. Holds object to another object that has a pre-threaded hole, frequently a nut. Usually manufactured from metal. Can be rotated into or out of the object using a screwdriver or wrench.

Review: Returned, however … - I feel guilty for returning such an inexpensive item using the vendor’s USPS label, so I gave it 5 stars. While it looks like a quality product, the photo used appears to be a generic one that the vendor uses for multiple sizes of screws. I ordered a dozen jute storage bins as well as casters from desertcart. To affix the casters to each bin, I needed 16 sets of bolts and nuts - 4 sets for each caster and bin corner. I went to a local small hardware store and a floor clerk found exactly what I needed — these 4-400 3/16 screws, along with nuts in another pull-out tray. Unfortunately this small size isn’t common, and the store only had enough screws to affix the casters to one bin. This vendor’s photo and size looked like a perfect match, but when it arrived I immediately saw that the screws were much shorter than appeared in the photo. If indeed these really are 3/16 long, apparently this measurement includes the screw head while the hardware’s store version of the same just measured the thread. I realize it takes more effort to photograph every unique item you sell on desertcart, but surely that would be more cost effective than providing the (much appreciated) return label. Finally, for all vendors, it would be good to sell complete sets of screw-washer nut in each size, as there are variations between manufacturers and vendors. I now need to go on a hunt for the screws that will work, town-to-town at the small hardware store chain, that sells these items by the piece rather than in large packages. Hopefully the next store will have plenty of the screws that work.
Review: Well made, good fit. - Kind of hard to screw up up screws(pun intended). They worked perfectly as expected :)
