At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM F541. Standard specification for forged, quenched and tempered alloy steel threaded eyebolts, intended particularly for low-temperature service where notch toughness and resistance to brittle fracture are required. Two types: Type 1 (straight/plain shank) and Type 2 (shoulder). Maximum thread size 2.500 in (63.5 mm).
