Black Oxide Hex Socket Head Cap Screws Bolts
product detail

• These screws have a cylindrical head with a recessed hexagonal drive (socket) for use with an Allen wrench or hex key. This design allows for greater torque to be applied compared to a standard slotted or Phillips head screw.
• They are commonly used in machinery, automotive, and other engineering applications where a strong, durable, and aesthetically pleasing fastener is required.
• The black oxide finish is a conversion coating that adds a layer of mild corrosion resistance and gives the screw a matte black appearance. The black oxide coating does not significantly affect the mechanical properties of the underlying metal. The black oxide finish can also help reduce light reflection, which may be beneficial in certain environments, such as theatrical productions or photography equipment.
• The screws are available in different grades, which determine their tensile and yield strengths. Higher-grade bolts will be stronger but may also be more brittle.
