A black oxide finish provides minimal corrosion resistance, best for indoor, dry environments. This finish is not suitable for outdoor applications, and will rust when exposed to moisture. Class 10.9 metric button head flange bolts are considered hardened, providing a high strength, high tensile fastening solution. Pair with Class 10 or stronger nuts.
These screws 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. Flange style button head screws are popular across a wide range of industries: automotive, furniture, agriculture, electronics, etc.
Use an allen wrench to install these screws. The slim design of an allen socket wrench allows access to tight locations where a traditional external hex drive bolt would not fit.
