Product Description
Socket Cap Screws are reliable and durable and are used in many applications. They are available in a variety of head styles and materials.
Alloy Steel is steel that has been alloyed with other materials to improve overall physical properties. Steels are designated by a 4 number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last 2 digits identify the percentage of carbon for the alloy (in hundredths). Tensile strength ranges for the alloys typically used in these fasteners range from 170,000 to 180,000 psi (pounds per square inch), making these amongst the strongest of materials.
Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits.
A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine.

Great screws, but don't let the pic fool you.
By Matthew Ryan Kohler
AS MENTIONED BEFORE, THESE ARE BLACK OXIDE SCREWS, NOT STAINLESS AS PICTURED. These are very high quality YFS screws. I've ordered 1000's of them and they come exactly as described. Very good value!

By rdagger
The screws are black (not silver as pictured). The heads are also wider than a normal screw. Otherwise no issues.

Not properly sized
By J. Jewell
They say 1/2" which universally means the threaded area plus any shaft that isn't threaded. But these 1/2' screws only have 1/4" of thread. They also say the head diameter is .75.... It is .375
