Dimensional tolerance ： ±0.2mm
Please provide product specifications so that we can offer specific pricing and MOQ.
Heavy duty stainless steel eye bolts are designed for harsh industrial environments. It uses AISI 304 or 316 stainless steel core material. Materials are reinforced. This allows it to maintain corrosion resistance for more than ten years in humid or chemical media. Its mechanical load-bearing capacity is excellent. For example, the safe working load of standard M20 specification products can reach 2.6 tons. The safety factor is as high as 4 to 1. This provides reliable protection for heavy-load applications.
This bolt has a wide operating temperature range. It can work stably between minus 50 degrees Celsius and 250 degrees Celsius. Therefore it is suitable for a variety of scenarios from refrigerated warehousing to high-temperature workshops. It should be noted that its load capacity changes significantly with angle. When the lifting direction is 90 degrees to the bolt ring, the safe working load will be reduced to about 30% of the vertical state. Precise mechanical planning is necessary during installation. Product specifications cover series from M8 to M36. This covers a full range of needs from light fixed to heavy lifting.

Advantages
billboard structural anchoring
Large outdoor steel structure billboards withstand huge wind forces on the windward side. When a billboard with an area of 100 square meters encounters a Category 12 typhoon (wind pressure is about 1.1 kPa), the nodes connecting the steel frame and the foundation need to withstand a total tensile force of about 11 tons. The use of multiple M24 bolts (single SWL 3.8 tons) for dispersed anchoring is the key to the structure's wind resistance.
Building hoisting connection
In prefabricated buildings, a single precast concrete room module can weigh up to 15 tons. Heavy-duty eyebolts are pre-embedded at the four corners of its steel structure frame as the only force-bearing point for lifting.
The SWL of each M36 bolt exceeds 8 tons. The four points work together to smoothly and safely complete the lifting, transportation and installation of the module.
Safety anchorage points
When performing maintenance on the interior of the box girder of the cross-river bridge, workers need to work on a mobile hanging basket. The hanging basket is connected to the preset M20 stainless steel eyebolts (SWL 2.6 tons) on the top of the box beam through wire ropes.
The anchor point is designed to withstand 4 times the impact load (approximately 10.4 tons) to prevent the hanging basket from accidentally falling. Its 316 material can resist corrosion from condensation water in the bridge box, ensuring that the anchor points can be safely used at any time within the 100-year design life of the bridge.
Openable skylight hinge base
In large openable skylight structures in stadiums or museums, the sash weighs 3 tons each and rotates on heavy-duty hinges. The core stress base of the hinge is anchored to the main steel structure using M24 stainless steel bolts (SWL 3.8 tons). In a test simulating a once-in-50-year wind load (wind pressure of about 0.8 kPa), the connection point needs to be able to withstand more than 2.5 tons of additional pulling force generated by the window sash to ensure that the skylight will not deform or detach in bad weather and is safe and reliable.
why choose us
Ultra-high mechanical strength
- Has high tensile and yield strength. Taking the M20 specification as an example, its safe working load can reach 2.6 tons, and the safety factor is usually 4:1 or 5:1, providing reliable guarantee for heavy-duty hoisting and fixing.
Clear safety regulations
- Comply with mainstream industry standards such as ASTM A489. Each specification has a clear safe working load identification, which facilitates accurate calculation and safe use by engineers, and effectively prevents the risk of overloading.
Easy and efficient installation
- Standard metric or imperial thread design, compatible with conventional tools. It can be directly screwed into prefabricated threaded holes or used with nuts to simplify the installation process and improve construction efficiency.
Excellent versatility
- Available in a variety of specifications from M8 to M36, they can meet different needs from light equipment fixing to heavy structure lifting. Its standardized design makes it a universal accessory across industries.
