• Premium Material: The NZNSML M4 black flanged button head socket cap screw is made of high-quality stainless steel, offering excellent rust and corrosion resistance. The black zinc plating enhances surface hardness and wear resistance, effectively extending the lifespan of screws. The threads are clear and complete, distributing force evenly, preventing stripping, and offering a strong and durable fastening effect.
• Flange Round Head Hex Socket: NZNSML black stainless steel bolts feature a flanged button head hex socket head cap bolt design. This design increases the contact area between the bolt head and the mounting surface after installation, improving equipment stability and preventing the bolt head from sinking into the object. The hex socket head cap design provides greater torque transmission capacity, makes installation easier, and is less prone to loosening.
• Practical Accessories: Each set of NZNSML M4 black zinc stainless steel flange round head hex bolts is equipped with black zinc stainless steel hex nuts, flat washers and spring washers of the corresponding size. Through the mechanical locking of the nuts, the pressure distribution of the flat washers and the continuous elastic pre-tightening of the spring washers, a practical anti-loosening system is formed, which can effectively resist loosening problems caused by equipment vibration.
