Hexagonal Shape - SWPI - Solid base for precision

Hexagonal prism: Imagine a regular hexagon standing upright, forming a 3D shape with six rectangular sides. This design offers stability and prevents rolling.
Tapered design (For heavier weights - Model No. SWPI:48-51 & SWPI:137-145): These weights might be wider at the bottom and taper slightly towards the top for better grip and stacking.
Flat and smooth surfaces: The sides should be flat and free of imperfections for accurate weight distribution.

High-grade cast iron (Grade 15 of IS : 210 : 1962): This ensures durability, resistance to wear and tear, and dimensional stability.
Cast-in handle (for heavier weights): Made from mild steel (IS: 1977-1962) for secure handling during lifting.
Black, corrosion-resistant paint: Protects the iron from rust and other environmental factors.

Each model number (SWPI:52-56, SWPI:21-25, SWPI:48-51, SWPI:137-145) likely represents a range of individual weight options within the specified weight bracket (50 g - 2 kg or 5 kg - 50 kg). Consulting the manufacturer's datasheet or contacting them directly is crucial to obtain the specific weight options available.
Tolerance: Weights should comply with international standards for accuracy, such as those set by OIML (International Organization for Legal Metrology). The specific tolerance level (maximum permissible deviation from the nominal weight) might vary depending on the weight class.
Loading hole: Heavier weights (Model No. SWPI:48-51 & SWPI:137-145) might have a hole on the underside for potential adjustment or attachment purposes.
Certification: The weights might be certified by accredited bodies to meet specific weight standards.
