ndustrial HSS Hexagonal Threading Dies | The Ultimate Solution for
On-Site Repair
Problem: Restricted Access and Rusted Threads
Maintenance engineers often face the nightmare of repairing a
damaged bolt thread located in a tight engine bay or deep inside a
machine frame. Standard round dies are useless in these scenarios
because the bulky die stock handle simply cannot fit into the
restricted space. When a structural bolt is severely rusted or
cross-threaded on-site, removing the entire component just to fix a
thread leads to massive downtime and labor costs.
Cause: Rigid Tool Standards and Space Constraints
Circular dies require specialized handles (die stocks) that rely on
symmetric lateral space for leverage, making them impractical for
field repairs. Standard alloy dies often lack the necessary
hardness to clean out "hardened rust" or high-tensile grit, leading
to broken teeth when high torque is applied via a wrench. Without a
hexagonal geometry, there is no way to utilize standard sockets or
adjustable wrenches, which are the primary tools carried by mobile
repair crews.
Solution: Hex-Drive Versatility with HSS Durability
Our HSS-M2 Hexagonal Dies are engineered for the "tough jobs" where space is a luxury and
reliability is a necessity. The hexagonal outer profile allows the
tool to be driven by any standard wrench, socket, or spanner,
turning every basic toolset into a precision threading station.
Manufactured from vacuum-hardened High-Speed Steel, these dies
provide the "bite" needed to restore damaged threads on Grade 8.8
and 10.9 fasteners with ease.

Application: Engineered for Field & Workshop
Automotive MRO: Perfect for cleaning head bolts, wheel studs, and manifold
fasteners where space is extremely limited.
On-Site Construction: Ideal for restoring threads on galvanized anchor bolts or rebar
that have been damaged during installation.
Agricultural Repair: A must-have for farm equipment maintenance, allowing for quick
field repairs without removing large heavy-duty parts.
Marine & Offshore: Reliable performance for clearing salt-corroded threads on deck
equipment and engine room components.
Selection Guide: Professional Integration
1. Across-Flats Sizing: Ensure your wrench or socket matches the "Across Flats" (A/F)
dimension of the hex die for a slip-free connection.
2. Directional Entry: One side of the hex die features a wider chamfer for easy
starting; always ensure this side faces the damaged thread first.
3. Torque Management: While hex dies allow for high torque via wrenches, always use
cutting oil to prevent the M2 edge from overheating.
4. Precision Matching: For critical structural repairs, verify the TPI or Pitch etched on
the die to ensure a perfect 6g fit.
Professional FAQ (Expert Support)
Q: Can I use a Hex Die to cut new threads from a blank rod?
A: Yes. While primarily used for repair, our HSS-M2 Hex Dies are fully
ground and sharp enough to cut brand new threads on mild steel and
alloys.
Q: What is the benefit of HSS over Carbon Steel for Hex Dies?
A: HSS-M2 provides significantly higher "Red Hardness," meaning the
teeth won't soften if the die gets hot while scrubbing through
heavy rust or hardened grit.
Q: Do these fit into standard Sockets?
A: Yes. They are designed to match standard metric and imperial wrench
sizes, making them compatible with your existing toolbox.
