Inconel 718 Screw to Coach Screws
Inconel 718 Coach Screws are premium-grade, heavy-duty fasteners engineered for demanding
structural applications exposed to extreme heat, pressure, and corrosion. Manufactured by
FERROBEND, a reputed Indian manufacturer and exporter, these screws are made from
UNS N07718 (2.4668 /
NiCr19Fe19Nb5Mo3)—a
precipitation-hardened nickel-chromium alloy known for exceptional tensile strength, fatigue
resistance, and thermal performance. Designed with a hexagonal head and
coarse lag thread, Inconel 718 coach screws are ideal for timber anchoring, marine structures,
offshore installations, and critical chemical plant assemblies. Produced to material
specifications such as
ASTM B637,
ASTM A1014,
ASTM F2281 and
EN 10269
they also meet dimensional
standards including
DIN 571, ASME B18.2.1, ASME B18.2.3.8M, and
UNI 704.
Available in Metric sizes (4mm to 20mm) and Imperial sizes (No. 10 to 1-1/4"), these coach screws ensure long-lasting performance and structural reliability in the most aggressive operating environments.
