【Durable 410 stainless steel】Our self-tapping sheet metal screws are made of 410 stainless steel, corrosion-resistant, rust-free, high-strength and non-deformable. 410 stainless steel is magnetic.

【Fast self-tapping】The drill-shaped tip of the self-tapping screws allows the screws to be used without pre-drilling, which saves the user time. They are used for metal-to-metal or metal-to-wood joints, which are commonly used in thin metal applications, such as when working with steel pins.

【Fine Finish】Black self-tapping screws with modified Phillips head provide a larger surface area to distribute the force and provide good holding power to prevent screw slippage and ensure a strong and reliable joint. Deep, clean threads tighten the joint.

【Well Packed】The package contains 290 pcs M4.8 black self-tapping screws and an extra Phillips drill bit.

【Versatile】Self-drilling screws for metal, wood, plastic. Self-drilling screws can be used for a wide range of applications. For metal, e.g. when working on metal roofs, heating, air conditioning and ventilation systems, pipelines and steel structures. For wood in the construction, repair or maintenance of sheds and outbuildings. For plastic in certain applications and environments.
