Bolts and Nuts

Sigma Engineering supplies a massive inventory of Mild Steel (M/S) Bolts, Nuts, and Washers specifically sized for mechanical and civil engineering projects. These fasteners are the "glue" of any infrastructure project, used for securing pump baseplates, flanged pipe connections, and structural supports.

Our fasteners are available in various lengths and diameters to meet the specific torque and load requirements of your installation.

Available Variants:

• M/S Bolts & Nuts: Available in 1/4", 3/8", 1/2", 5/8", and 7/8" diameters with lengths ranging from 1 1/2" up to 10" for heavy-duty anchoring.

• M/S Washers: Available in matching sizes (3/8" through 1") to ensure load distribution and prevent surface damage to your equipment.

Applications

1. Flange Connections: Specifically sized 5/8" and 1/2" bolts are ideal for securing pipe flanges in high-pressure water lines.

2. Equipment Mounting: Long-reach 1/2" x 10" bolts are used for anchoring heavy electric motors and pumps to concrete plinths.

3. General Repair: A must-have for any maintenance workshop to ensure immediate repair of mechanical structures.
