At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to SAE J105. SAE J105 ‘Hex Bolts’ – a dimensional/part standard defining the geometry (across-flats, head height, thread lengths) of hexagon-head bolts in inch series. It is a dimensional standard, not a material grade standard; strength is set by the SAE J429 grade marked on the bolt. SAE J105 was cancelled in January 1990 and superseded by ASME/ANSI B18.2.1.
