At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of ASME B18.10. ASME B18.10 (Inch Series) covers track bolts and their nuts used to join rails at rail joints (fishplates/joint bars) in railway track. Bolts have a button (oval) head with an oval neck that seats against the joint bar to resist rotation. Table shows representative common track-bolt sizes; exact head geometry per the ASME B18.10 button/oval-neck tables.
