To be the partner steel plants, railway divisions and engineering companies turn to first for IS and RDSO fasteners, custom bolting and fabrication support.

Four decades in India's steel belt
S A Engineering works from 99/C, Raipur–Bhilai–Durg Expressway in Bhilai's Light Industrial Area. Bhilai is one of India's great steel towns, and for forty years the business has grown alongside the plants, rail divisions and engineering units around it.
The work began as general engineering and metal fabrication. Over time it narrowed to what our customers needed most: bolts that match the drawing exactly and arrive when the job needs them. Today we make high-strength hex bolts from M12 to M64, fish bolts and track bolts to RDSO drawings, railway plate screws, foundation bolts and specialised bolts to customer drawings.
Our customers include SAIL Bhilai Steel Plant, Indian Railways, Indian coal-field units, Gopal Industries and BSNL.
