At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM F912/F912M. Standard specification for alloy steel socket set screws (hexagon socket, various points), inch (F912) and metric (F912M) series, quenched and tempered. Set screws are hardness- and holding-power (seating torque) governed rather than tension-rated. Sizes per ASME B18.3 / B18.3.1M.
