Q: What are the standard dimensions for M6 and M8 flat washers?

A: M6 flat washers typically have an inner diameter of 6.4mm and outer diameter of 12mm. M8 flat washers usually measure 8.4mm (inner) and 16mm (outer), with thicknesses around 1.6mm. Always verify against ASME/ISO standards for specific applications.

Q: Where can I find a flat washer weight chart?

A: Flat washer weight charts are available from industrial suppliers or engineering handbooks. Weights vary by material (steel, stainless, etc.) and dimensions – a 1/2" flat washer weighs approximately 3-5 grams in steel. Digital calculators can estimate weights using thickness and diameter inputs.

Q: What size is a 1/2" flat washer in metric measurements?

A: A 1/2" flat washer converts to ~12.7mm inner diameter. Standard outer diameter is typically 25mm (1") with 2-3mm thickness. Metric equivalents may be labeled as M12 washers in some specifications.

Q: What are the dimensions of an M12 washer?

A: An M12 flat washer generally has a 13mm inner diameter and 24mm outer diameter. Thickness ranges from 2.5mm to 3mm depending on material grade. These dimensions align with ISO 7089 standards for heavy-duty applications.

Q: How do I choose between M6, M8, and M12 washers?

A: Select based on bolt diameter: M6 for 6mm bolts, M8 for 8mm bolts, and M12 for 12mm bolts. Consider load requirements – M12 handles higher stresses. Always cross-reference with washer size charts for proper fit and function.
