FORM B

FORM B

Form B washers are light-duty flat metric fasteners governed by British Specification BS 4320.

They feature a normal outside diameter (OD) but a significantly thinner profile than standard Form A washers.

This slim design makes them the definitive choice for precision engineering and tight mechanical assemblies where weight reduction or minimal thread clearance is required.

Commonly manufactured to conform with BS 4320 and often cross-referenced with DIN 125B.
