Thread rolled Hex Bolts

Rapid Industrial Fasteners – thread rolled hex bolts engineered for strength and speed.

M52 thread rolled hex bolt production

Our latest batch of M52 hex bolts were expertly thread rolled from M52 x 400 bolt blanks. Within just five working days we completed 290 units of thread rolled hex head bolts, delivering fully finished heavy duty fasteners to the exact specifications, on time.

This process is more than just efficient, it’s transformative, with thread rolling contributing to;

30% increase in tensile strength

50–75% greater fatigue resistance

With 100% RAPID turnaround

Such enhancements make these bolts ideal for structural and heavy-duty industrial uses where performance, durability and lead time are non-negotiable.

For critical applications, particularly in construction, engineering, and infrastructure.

Why does thread rolling make a difference?

Thread rolling is a cold-forming process that displaces the material to form threads rather than cutting them. The results offer a superior surface finish, improved dimensional accuracy and work-hardened thread flanks that enhance fatigue strength and durability.

When comparing to traditionally cut threads, thread rolled hex bolts also offer, greater structural integrity, improved load distribution and a reduced risk of failure under cyclic loads.

M52 built for high-performance applications

With their large diameter and 8.8 grade tensile strength, the M52 hex bolts are often found in infrastructure projects, wind turbines, heavy machinery and bridge assemblies.

With their substantial diameter and impressive 8.8 grade tensile strength, our M52 hex bolts are engineered to handle some of the most demanding structural applications. These high-performance fasteners are commonly utilised in large-scale infrastructure projects where reliability and load-bearing capacity are critical. Their robust construction makes them ideal for use in wind turbines, where they help secure massive components subjected to high stress and fluctuating environmental conditions. Similarly, in the realm of heavy machinery and industrial equipment, M52 hex bolts provide the strength needed to maintain structural integrity under extreme mechanical loads. Additionally, these bolts play a vital role in assemblies, anchoring crucial elements and ensuring long-term stability in both static and dynamic conditions.

Their durability and strength make them an essential component in any project where safety and structural performance cannot be compromised.
