Double Folded Bolt MK-ST-3-10-1

• 1. Integrated cold heading for seamless high strength

Made from solid metal bar via cold heading followed by CNC machining; free of welding defects with dense structure to avoid breakage risk.

• 2. Precision rivets for enhanced torsion resistance

Precision build resists lateral torsion; stays smooth and stable without wobble or loosening after repeated opening and closing.

• 3. 10,000-cycle fatigue tested with certified quality

Passes rigorous 10,000-opening fatigue test and maintains superior performance under frequent heavy-duty use.

• 4. Surface Hardened, Wear & Corrosion Resistant

Specially surface hardened for superior abrasion resistance against frequent disassembly scratches. Anti-corrosion treatment prevents rust & oxidation under humid or corrosive surroundings, securing long-term stable connection.
