Detail & Specs
Flat head cap screws have a 90 degree angle underneath the head. When installed, the head of this screw is meant to sit flush with the surface of the work in a countersunk hole.
Measured by overall length, including the head.
A black oxide finish provides minimal corrosion resistance, best for dry environments.
Class 10.9 metric flat head bolts are considered hardened, providing a high strength, high tensile fastening solution. Pair with Class 10 or stronger nuts. These bolts can be used with many different styles of locking and non-locking nuts, tightly clamping together whatever the cap screw is being used to secure.
Also known as a countersunk allen head machine screw, hex drive flat head countersunk socket cap bolt.
