PRECISION DIMENSIONS: Features 3 outer diameters (20mm/25mm/32mm) with inner holes from 2-12mm. Uniform 1.5mm thickness ensures consistent load distribution and surface protection.
HEAVY-DUTY ZINC PLATED STEEL: Grade 4.8 carbon steel construction with corrosion-resistant zinc plating withstands high-pressure applications in harsh environments.
SUPERIOR LOAD DISTRIBUTION: Extra-large surface area (especially 32mm OD) prevents bolt pull-through, reduces vibration, and protects soft materials like wood/drywall. Ideal for structural repairs and leak sealing.
ORGANIZED STORAGE CASE: including durable compartment boxes, perfect for portable use on construction sites.
