Color classification
12.9 Grade black plastic head buffer plunger screws are precision-engineered for industrial stop, tightening, and shock absorption applications, featuring POM/nylon plastic heads and high-strength alloy steel construction. Available in metric sizes M2 to M10, these machine fasteners deliver reliable buffer performance, precise position limiting, and durable tightening for machinery parts, equipment assemblies, and automated production line components that require anti-collision, shock absorption, or fixed-position locking.
 
Crafted to 12.9 Grade high-strength standards, the metal body ensures superior tensile and torque resistance for heavy-duty industrial use, while the black POM/nylon plastic head provides excellent wear resistance, impact buffering, and noise reduction—preventing surface scratches on precision components and absorbing vibration during machinery operation. Designed for direct installation on standard metric tapped holes, these plunger stop screws balance structural rigidity with flexible buffer functionality, ideal for quick positioning and secure tightening in mechanical equipment.
