Eye Bolts Manufacturer
MT.BOLTS manufactures Eye Bolts, which are externally threaded fasteners featuring a loop (eye) at one end, designed primarily for lifting or securing cables, ropes, chains, or rigging hardware. These bolts are widely used in construction, marine, industrial lifting, and structural anchoring applications due to their strength, reliability, and load-bearing capabilities. MT.BOLTS offers high-performance eye bolts in a range of materials, thread sizes, and configurations to meet stringent safety and engineering standards.

FAQ About Eye Bolts
Only shoulder eye bolts are suitable for angular lifting. Plain eye bolts must be used strictly for vertical loads.
Forged eye bolts are one-piece and suitable for heavy loads; bent eye bolts are formed from wire and used for light-duty anchoring.
Stainless steel eye bolts are highly corrosion-resistant, especially when passivated, making them ideal for harsh and marine environments.
Use ASME B18.15, DIN 580/582, ISO 3266, or BS 4278, depending on your region and lifting requirements.
Yes, if they are not deformed, corroded, or worn. Always inspect before reuse, especially in critical lifting applications.
