Nuts

M6 – M72 | Grade 4 to 10

Hex Nut

Standard hexagonal nuts manufactured to IS 1364 and DIN 934. Available in grades 4, 5, 8, and 10 to match all corresponding bolt grades. Black, zinc-plated, and hot dip galvanized finishes for indoor and outdoor applications. Suitable for structural steel, machinery, transmission towers, and all general industrial fastening.

M6 – M56 | Nyloc & All-Metal

Lock Nut

Prevailing torque lock nuts that resist self-loosening under vibration, shock, and dynamic loads. Available in nylon insert (Nyloc) for general vibration environments and all-metal for high-temperature applications up to 300°C. Essential for transmission towers, automotive, and any machinery subject to continuous movement.

M6 – M56 | 1.5D to 3D Length

Long Nut

Extended length coupling nuts (long nuts) for joining two threaded rods end to end, extending effective bolt lengths, or connecting threaded components in tension. Available in 1.5D, 2D, and 3D standard lengths or fully custom. Hex and round (coupling nut) profiles available. Ideal for foundation bolt assemblies and structural tie rod systems.

M6 – M12 | Spring Steel

Spring Nut

Spring steel channel nuts for quick tool-free snap-in installation in strut channel, unistrut, and cable tray support systems. Insert into the channel opening and rotate 90° to lock. Compatible with standard 41×41mm and 41×21mm strut profiles. Available in zinc-plated and HDG finishes for indoor and outdoor use.

M16 – M36 | Grade 8.8 & 10.9

HSFG Nut

High Strength Friction Grip (HSFG) nuts manufactured to IS 6623 for use exclusively with HSFG bolts in slip-critical structural steel connections. Engineered to develop the full clamping force required for friction-type joints. Available in Grade 8.8 and Grade 10.9 with black and hot-dip galvanised finishes. Used in bridges, transmission towers, industrial steel structures, and heavy fabrication where joint integrity under dynamic, shear, and fatigue loads is critical.
