Adopting top-grade alloy steel as raw material, these long screws own solid hardness, excellent tension capacity and great abrasion resistance. Delicately processed threads plus professional heat treatment enable stable structure and permanent fastening effect. Widely used for hydraulic breaker and excavator assembly, they are durable and labor-saving to mount.
Why Choose Guangzhou Huilian?

1. Premium Material Science & Forging Process
While others use standard high-tensile steel, we employ a specialized alloy steel, formulated for impact tools. It undergoes a controlled forging and heat-treatment process that creates an optimal balance of extreme surface hardness (for wear resistance) and a tough, ductile core (to absorb shock and prevent sudden fracture). This results in studs that resist stretching, threading, and fatigue far longer than common alternatives.

2. Precision Thread Integrity & Consistency
Our studs are not merely turned; their threads are precision-rolled after heat treatment. This cold-working process strengthens the grain structure along the thread roots—the most common point of failure. This guarantees perfect thread engagement, eliminates premature loosening, and ensures consistent, reliable clamping force across all studs in every set.

3. Advanced Anti-Fatigue Design
We incorporate radiused fillets at critical stress transition points (under the head and between thread runs) instead of sharp corners. This design dramatically reduces stress concentration, the primary cause of fatigue failure under cyclic loading. Competitors' studs with machined sharp corners are significantly more prone to cracking at these points.

4. Superior Corrosion & Galling Resistance
A proprietary surface treatment combination is applied. It includes a phosphate coating for corrosion resistance and enhanced lubrication retention, plus a premium anti-seize compound pre-applied to threads. This prevents seizure during installation/removal, protects against rust in harsh environments, and ensures proper torquing, directly extending service life.

5. Guaranteed Dimensional & Performance Consistency
Every batch of our long studs is manufactured to exacting OEM-level tolerances. This ensures perfect fitment, uniform load distribution, and eliminates the risk of misalignment that can cause premature wear on the breaker body, tool bushings, and the studs themselves—a common issue with lower-grade replacement parts.

6. The Result: Maximized Uptime & Lower Total Cost of Ownership
The ultimate advantage is not just in the component, but in the performance it enables. Our long studs:

  • Extend service intervals by maintaining proper clamping force longer.

  • Protect your major investment by preventing catastrophic breaker casing damage due to stud failure.

  • Reduce unscheduled downtime and associated labor costs from frequent replacements.
