LGRIG® Stainless Eye Bolts & Nuts — Lift Straight, Pull Angled, Trust the Shoulder.
From marine deck fittings to architectural shade structures and industrial lifting, QINGDAO LG RIGGING CO.,LTD delivers the LGRIG® range of stainless steel eye bolts and nuts — engineered for superior corrosion resistance, dependable load capacity, and long service life in demanding environments.
Our comprehensive lineup covers every configuration: DIN580 lifting eye bolts and DIN582 lifting nuts for standard rated lifting applications; shoulder eye bolts with a reinforced collar underneath the eye for angular pulls and side-loading resistance; plain eye bolts for straight-line, zero-degree lifts only; lag eye bolts with wood screw threads for secure attachment to timber structures both indoors and outdoors; and machinery eye bolts designed for threaded holes in equipment.
Available in stainless steel 304 for general corrosion resistance or marine grade 316 for superior protection against saltwater, humidity, and chemical exposure, with both rated (independently certified with clear working load limits) and non-rated (economical for low-load applications) options to match your requirements.
Whether you are lifting machinery, securing wire balustrades, rigging shade sails, or anchoring marine equipment, LGRIG® stainless steel eye bolts and nuts deliver the strength, corrosion resistance, and reliability that engineers, riggers, and contractors trust — in every lift, at every angle.
Do not paint or otherwise coat the eyebolt & nut, as this will make it difficult to check for defects or wear due to the masking of the coating.
If you find that the eyebolt & nut is worn or damaged, remove and replace them immediately; wear and damage will significantly reduce the load capacity of the eyebolt. Please also check the eyebolt & nut regularly: whether the eye is bent out of shape; whether the threaded shank is bent, deformed or the threads are worn, corroded or twisted; whether there are scratches, shavings, or visible wear on the surface; whether there are signs that it has been modified in any way, e.g. by heating, cutting, grinding, welding, etc.; whether there are cracks on the surface; whether it lacks sufficient identification marks.
Do not exceed the rated capacity of the eyebolt.
Do not force the sling through the eyebolt; although convenient, this provides an angled lift which will reduce the WLL of the eyebolt.
Do not attach hooks or other accessories directly to the eyebolt, they should be attached to the eyebolt by means of a shackle, please select the appropriate grade of lifting shackle.
Do not rotate the load, this is very dangerous and the twist can damage the eyebolt and accessories, it can also cause the accessories to slip off and pose a danger to personnel and equipment.
The eyebolt should be lifted slowly and gradually, do not shock the load, sudden acceleration of the load or rapid changes in direction can cause a significant increase in load tension.
Always check and clean the eye bolt holes and threads before use, as the receiving holes should be countersunk, so also clean any debris from the receiving holes to ensure the eye bolt is seated correctly.
The shoulder eye bolt must be firmly seated and flush with the mating surface, not at an angle to a flat surface, otherwise, the WLL will be greatly reduced. Washers, spacers and nuts can be used with the shoulder eye bolt to achieve correct load alignment. However, it is important to note that the thickness of the washers and spacers should not exceed one thread pitch.
The shoulder should be installed at right angles to the axis of the hole and the shoulder should be in full contact with the surface of the object being lifted.
Check the coordinates after the angular lift has been applied and if it happens that the first lift causes the bolt to back out of the load, the eyebolt should be unloaded and properly repositioned.
For applications without through holes, it is recommended to use a longer shoulder eye bolt with steel washers and nuts to achieve the required engagement thread length.
The tapped hole of the shoulder eye bolt should have a threaded length to ensure full-length engagement of the shank and clearance of the unthreaded portion, the tapped hole of the plain eye bolt must be threaded for full-length engagement and must also have full-threaded shank engagement, allowing half a turn for proper eyebolt alignment and WLL. The depth of the tapped hole of the screw eye bolt should be at least 1.5 times the diameter of the eyebolt.
The eye bolt should be oriented in line with the sling, if the load is applied laterally the eyebolt will bend.
