Hex Bolts

M6 – M72 | Grade 4.6 to 10.9

Full Thread Bolt

Hex bolts threaded along the entire length of the shank from head to tip. Full threading allows maximum flexibility in clamping length and is preferred where the bolt length needs to be adjusted at site or where nuts need to be positioned anywhere along the shank. Widely used in structural steel, foundation bolt assemblies, machinery mounting, and general industrial fastening. Manufactured to IS 1364 and DIN 933 standards in grades 4.6 to 10.9.

M20 – M36 | Grade 4.6 to 10.9

Square Head Bolt

Square head bolts with a four-sided wrenching head that provides a larger bearing surface and stronger wrench grip compared to standard hex bolts. Available in full and partial thread configurations across grades 4.6 to 10.9. Manufactured to IS 2585, DIN 478, and ASME B18.2.1 standards. Supplied in black, zinc-plated, and HDG finishes. Used in structural steel, transmission towers, timber connections, railway infrastructure, and heavy machinery assemblies where high torque and positive wrench grip are essential.

M16 – M72 | Grade 4.6, 8.8, 10.9

CSK Bolt for Crushers

Heavy-duty countersunk (CSK) bolts specially manufactured for crusher liner and jaw plate fastening. The flat conical head seats flush within the countersunk hole of the liner, eliminating any protruding bolt head that would be struck and destroyed by feed material. Available in high tensile grades 8.8 and 10.9 with hex socket or square neck drive. Manufactured in alloy steel with black oxide and HDG finishes. Compliant with ISO 10642 and DIN 7991 standards for use in jaw crushers, cone crushers, impact crushers, and VSI machines.

M6 – M72 | Up to 500mm | Grade 4.6 to 10.9

Half Thread Bolt

Hex bolts with partial threading where only a portion of the shank is threaded, leaving a smooth unthreaded grip section beneath the head. The unthreaded shank bears the shear load while the threaded portion handles clamping — making it ideal for joints where bolts pass through multiple plates or timber connections. Available in grades 4.6 to 10.9 in black, zinc-plated, and HDG finishes to IS 1364 and DIN 931 standards.

M24 – M72 | 200mm - 1500mm | Grade 4.6, 8.8, 10.9

T Head Bolt

T-shaped head bolts designed to slide into T-slots on machine tool tables, jigs, and fixtures — locking in place with a 90° rotation so no access to the bolt head is needed from above. The T-head sits flush within the slot and resists rotation during tightening. Available in grades 4.6 and 8.8 in black and zinc-plated finishes. Manufactured to DIN 787 and ISO standards for use in machine beds, CNC tables, and structural channel systems.

M24 – M72 | 125mm - 1500mm | Grade 4.6, 8.8, 10.9

Oval Head Bolt

Oval or round countersunk head bolts with a domed bearing surface that sits flush or slightly above the material surface, providing a smooth finished appearance. The curved head distributes clamping load over a wide area while avoiding sharp edges at the surface. Available in grades 4.6, 8.8 and 10.9 in black, zinc-plated, and HDG finishes. Used in timber connections, agricultural equipment, conveyor systems, and general fabrication where a smooth snag-free surface is required.
