FORM G

FORM G

Form G washers are the largest and thickest standardised metric flat washers available under British Specification BS 4320.

They feature an outside diameter (OD) that is approximately three times the size of the inside bolt thread diameter, coupled with a heavy, reinforced thickness profile.

This extreme surface area makes them the definitive "heavy-duty" choice for structural wood, soft plastics, and heavy engineering.
