Hammer Drive Anchor Bolt Steel, Zinc plated, Size M16, M20

Product Highlights: Yellow Zinc Plated Nail Drive Anchors (Sizes M16 & M20)

• High Performance (Ultra Heavy Duty): Manufactured from high-grade steel specifically engineered for heavy structural loads and critical weight-bearing applications. Offers exceptionally high tensile and shear load capacities, ensuring maximum structural integrity (refer to specification table).
  
• Easy Installation: Fast and simple installation even for large anchor sizes. Just drill the hole, insert the anchor, and drive the pin completely home without needing a torque wrench. Saves significant time and labor on demanding job sites.
  
• Durable: Heavy-duty yellow zinc plating provides superior corrosion resistance and weather protection, making it ideal for both indoor and outdoor structural installations.
  
• Premium Component: Comes complete with a specialized, heavy-duty Cornicle Washer Nut that maximizes clamping force and load distribution.
  

Suitable Applications:
LST Fasteners Yellow Zinc Plated Nail Drive Anchors in sizes M16 and M20 are engineered for securing extremely heavy equipment, structural steel, or heavy machinery to reinforced concrete floors and walls requiring maximum stability.

Application Examples:

• Heavy Steel Structures: Anchoring steel column base plates, bridge structures, large-scale roof trusses, and heavy-duty pre-engineered building extensions.
  
• Heavy Machinery Installation: Securing massive industrial machinery bases, power presses, or stamping equipment (works seamlessly with the Cornicle Washer Nut to deliver exceptional vibration resistance).
  
• Warehousing & Logistics: Installing high-bay and automated heavy-duty pallet racking systems designed for massive weight loads.
  
• Outdoor Systems & Infrastructure: Securing heavy main utility pipe supports, high mast lighting poles, tower signs, and massive outdoor billboard structures subjected to high wind loads.
  

"Superior Performance with Specialized Cornicle Washer Nuts"

LST Fasteners Nail Drive Anchors come equipped with a specialized conical spring washer nut, known as a Cornicle Washer Nut. This design delivers clear operational advantages over conventional flange nuts:

• Superior Clamping Force: Standard flange nuts feature a flat base that offers limited load distribution and inconsistent contact on uneven surfaces. The conical shape of the Cornicle Washer Nut functions like a spring washer, ensuring even pressure distribution across the entire contact surface and significantly boosting frictional grip.
  
• High Vibration & Loosening Resistance: Standard flange nuts are prone to backing off under continuous operational vibrations. The built-in spring action of the Cornicle Washer Nut provides superior resistance to vibration-induced loosening, making it ideal for heavy machinery anchor points and wind-exposed structures.
  
• Plate Surface Protection: The rigid base of standard flange nuts can score or damage base plates when over-torqued. The conical design of the Cornicle Washer Nut absorbs excess tightening stress, minimizing surface scratches and damage to your workpieces.
  

Summary: Choosing M16 and M20 nail drive anchors equipped with Cornicle Washer Nuts ensures your heavy structural anchor points achieve ultimate stability, maximum load capacity, and superior vibration resistance—delivering long-term safety and cost-efficiency over traditional anchoring systems.
