Key Features & Benefits

Heavy-Duty Construction & Superior Load Capacity

Manufactured from premium-grade carbon steel (galvanized/black finish) or marine-grade SS304/SS316 stainless steel, this Lifting Screw Eye Bolt offers exceptional mechanical properties. The forged one-piece construction eliminates weak points, while the precise threading ensures maximum engagement depth. Unlike standard eye bolts, our long thread design provides deeper anchoring for enhanced pull-out resistance, making it suitable for lifting operations up to rated Working Load Limits (WLL). The material undergoes rigorous heat treatment to achieve optimal hardness and ductility balance.

Extended Thread Design for Versatile Installation

The Long Thread Lifting Eye Bolt features an elongated shank that accommodates thicker mounting surfaces and allows for secure through-bolt installations. This design enables proper nut engagement on the reverse side when mounting to steel structures, machinery bases, or wooden beams. The generous thread length provides flexibility in material thickness compatibility, eliminating the need for spacers or washers in most applications.

Technical Specifications

Usage Scenarios

Industrial Machinery & Equipment Lifting

The HX Long Thread Eye Bolt is essential for manufacturing facilities requiring secure lifting points for heavy machinery installation, maintenance, and relocation. Use M10 sizes for industrial presses and generators, M8 for mid-sized pumps and motors, and M6 for control panels and electrical enclosures. The long thread design ensures secure mounting through thick steel gussets and machinery bases.

Construction & Infrastructure Projects

Construction contractors rely on these Screw Eye Bolts for temporary and permanent rigging applications. Ideal for securing scaffolding anchors, hoisting building materials, and creating attachment points for fall protection systems. The galvanized finish withstands outdoor exposure during multi-year construction phases.

Marine & Offshore Applications

Marine-grade SS316 variants excel in shipbuilding, dock construction, and offshore platform maintenance. Use them to secure lifeboat davits, rigging hardware on sailing vessels, or lifting points for engine components. The extended thread accommodates thick fiberglass or wooden deck structures common in marine environments.

Warehouse & Logistics Operations

Create overhead lifting points in warehouses for hoist systems, conveyor maintenance, and inventory handling. The M8 and M10 sizes are particularly suited for pallet racking installations and overhead crane attachment points, facilitating safe material handling operations.

FAQ

What is the difference between carbon steel and stainless steel eye bolts?

Carbon steel eye bolts offer higher strength-to-cost ratio and are ideal for indoor or temporary outdoor applications when galvanized. Stainless steel (304/316) provides superior corrosion resistance for permanent marine, chemical, or food-processing installations where rust prevention is critical. 316 grade contains molybdenum for enhanced chloride resistance in saltwater environments.

Can these eye bolts be used for angular lifts?

While designed primarily for vertical lifts, the HX Long Thread Eye Bolt can accommodate angular loading up to 45° with appropriate derating (typically 25% reduction in WLL). For frequent angular lifting, consider our swivel hoist ring series designed specifically for multi-directional loads. Never exceed the marked WLL under any configuration.

How do I determine the correct thread length for my application?

The long thread design requires minimum engagement depth of 1.5× bolt diameter (e.g., 15mm for M10) into solid material. For through-bolt applications, ensure sufficient thread protrusion for full nut engagement plus 2-3 threads visible beyond the nut. Contact our technical team for thickness calculation assistance.
