JIS1168 Stainless Steel 304 Lifting Eye Bolt M4-M20

Industrial Machinery & Equipment Lifting

The JIS1168 Eye Bolt serves as a critical structural component in manufacturing plants and maintenance workshops. Formed through an advanced integral forging process, each piece emerges as a solid, unyielding unit with exceptional tensile strength. The cold, smooth touch of the stainless steel reflects its rigorous manufacturing standards, while the precision-cut threads ensure immediate, secure engagement with tapped holes. Install these permanently on electric motors, heavy-duty gearboxes, and industrial compressors to create reliable lifting points for complex installation, relocation, and repair operations.

• Thread Specifications & Compatibility: Machined to strict JIS 1168 standards, available in M4-M20 metric threads, and fully compatible with DIN, ANSI, and GB international fastener systems for global facility integration.
• Load Capacity & Safety: Clearly marked Working Load Limits (WLL) provide operators with immediate visual confirmation of safety thresholds during rigorous mechanical lifts and overhead positioning.
• Environmental Resistance: The forged construction resists the harsh realities of shop-floor environments, effectively shrugging off chemical washdowns, oil spills, and abrasive particulates to maintain structural integrity.

Marine & Coastal Applications

For boats, yachts, and dockside equipment, fastening points must endure relentless environmental exposure and dynamic mechanical stress. The SS304 Lifting Eye Bolt delivers exceptional performance for above-deck rigging, cabin fittings, and coastal structures where periodic freshwater washdowns are part of standard maintenance. The eyelet features a meticulously polished, burr-free inner radius, which actively prevents the chafing and premature wear of synthetic ropes and wire cables during constant movement.

To meet the highly specific demands of marine engineering, we provide comprehensive Customization and OEM services. Whether your project requires non-standard thread lengths, specialized shank dimensions, or modifications for unique davit and block-and-tackle systems, our engineering team adapts the core design to your precise operational requirements. This ensures that every component integrates perfectly into your existing maritime infrastructure without compromising on load-bearing capabilities.

FAQ

Is the JIS1168 Eye Bolt suitable for overhead lifting?

When properly installed into a load-bearing structure capable of supporting the intended weight, and used strictly within the specified working load limit and angular loading guidelines, these eye bolts excel in both vertical and angular lifting operations. Safety in high-risk overhead rigging is our primary engineering focus. Before leaving our facility, these components undergo rigorous tensile testing and multi-stage quality control procedures to guarantee 100% structural integrity. Operators must always verify that the tapped hole depth matches the shank length and that the mating material possesses adequate sheer strength. Never exceed the rated capacity stamped on the hardware. For critical overhead applications involving complex weight distribution, we strongly advise consulting a qualified rigging engineer to calculate exact dynamic loads.

What is the difference between 304 and 316 stainless steel for lifting eye bolts?

The SS304 alloy offers excellent baseline corrosion resistance for the vast majority of industrial, indoor, and light marine applications, providing a highly cost-effective solution for standard rigging needs. It maintains a bright, clean finish even after repeated exposure to shop fluids and humidity. Conversely, the SS316 variant contains added molybdenum, which significantly boosts its resistance to pitting from chlorides and harsh saltwater. This makes 316 the mandatory choice for submerged marine environments, offshore platforms, or chemical processing facilities exposed to corrosive vapors. For standard lifting hardware where regular inspection is possible, the 304-grade delivers optimal value and mechanical reliability. We readily supply the 316-grade upon request for projects facing aggressive, highly corrosive environments.
