We manufacture hex bolts in these main types, each available in multiple sizes and finishes.
MS Hex Bolts (Mild Steel Hex Bolts) are widely used in general construction and engineering projects.
8.8 Grade Hex Bolts are high-tensile fasteners designed for medium to heavy-duty applications.
10.9 Grade Hex Bolts are heavy-duty fasteners suitable for demanding industrial environments.
GI Hex Bolts (Galvanized Iron Hex Bolts) are coated to provide excellent corrosion resistance.
We manufacture hex bolts in metric coarse-pitch sizes from M8 to M48, in full-thread and half-thread configurations. Use the table to check thread pitch, spanner size and head height before you request a quote.

Thread pitch: Coarse pitch is standard. Fine pitch and custom lengths are available on request.
Length availability varies with diameter and thread type. Lengths above 300 mm and non-standard sizes can be made to your drawing.
Share the diameter, length, grade (4.6, 8.8 or 10.9), finish and quantity, and we will reply with a quote.
The right hex bolt depends on the load, the environment and the joint. Here are the main uses of our hex bolts, with the grade and finish buyers usually choose for each one.
Column base plates, beam-to-column joints, purlin and girt fixing, and bracing in pre-engineered buildings, warehouses and sheds.
Angle-section joints in lattice towers, where bolts see wind load, vibration and years of outdoor exposure.
Module rails, purlins and ground-mount frames that stay outdoors for 20 years or more and need good corrosion resistance.
Machine bases, gearbox and motor mounting, press frames and fabricated equipment that carry heavy and repeated loads.
Frames, idler brackets, hoppers and chutes in cement, steel, mining and bulk-handling plants where vibration loosens weak joints.
Chassis, axle and suspension brackets, and other high-load joints in trucks, trailers and earth-moving equipment.
Track accessories, bridge and platform steelwork, and roadside structures such as signage gantries and crash barriers.
Workshop fabrication, gates, racks, frames and everyday engineering jobs that do not need a high-strength bolt.
