Product Description

The class 12.9 alloy steel socket cap screw has a plain finish and a flat head with an internal hex drive, and meets Deutsches Institut für Normung DIN 7991 specifications. Class 12.9 alloy steel, composed of quenched and tempered alloy steel, is often used in applications where strength is the primary consideration. The material is magnetic. The flat head is cone shaped for use in countersunk holes and has a flat top that fits flush with the mated surface. The internal hex drive, also known as a hex-socket drive, has a hexagonal slot that requires an Allen key driver, also known as a hex key or Allen wrench.

Socket cap screws are threaded fasteners that have a cap head with an internal socket drive for installing in areas with limited side clearance. These screws are available with a variety of head shapes, which determine how the screw interacts with the mating surface, and drive styles, which determine the type of tool required to install the screw.

Item is listed as being fully threaded and even though the picture shows a partial threaded screw I purchased anyway hoping the description was correct. As it turns out, the description WAS wrong and these are only partially threaded.

Received my order of these they were not flat head and worse they don't even appear to be metric. Oh and if they were metric they would be a whole size too small... In fact everything about these bolts is wrong. On principle I would normally return these but its probably just not worth the effort for the cost.

Even though Amazon lists these as flat head, they are button head!? I ordered a different size too and those were supposed to be flat head but were button head?

My screws were exactly as described. Strangely I couldn't find these at McMaster, so I'm glad I found them here.
