An MS eye bolt is a mild-steel fastener with a circular eye at one end and a threaded shank at the other. Screwed into a tapped hole or secured with a nut, it creates a defined attachment point for anchoring, suspension or handling once its size, thread and load direction are confirmed.
Also known asMild steel eye bolt · Threaded eye bolt · Lifting eye bolt (where rated)
Key takeaways
Mild steel suits general indoor and protected industrial service.
Thread size, shank length and eye dimensions define the part.
Load direction matters: eye bolts are strongest in line with the shank.
Lifting use requires a confirmed rating and applicable standard.
How MS Eye Bolts Work in Practice
The MS eye bolt is one of the most widely used connection points in industrial assembly. Its eye accepts a shackle, hook, rope or link, while the threaded shank transfers the load into the parent component.
Its suitability depends on more than diameter alone. Eye geometry, thread engagement, mounting surface, load direction, finish and service environment all influence the correct selection. Lohar Industrial Fasteners reviews these inputs before confirming the supply scope.
Common MS Eye Bolt Forms
01
Collared (shoulder) pattern
A collar seats against the mounting surface, improving resistance to angular loading when fully seated.
02
Plain shank pattern
No collar; intended mainly for in-line loading where the force acts along the shank axis.
03
Long shank with nut
Passes through a clearance hole and is secured with a nut and washer on the far side.
04
Forged or formed eye
The eye can be forged integrally or formed from bar; the production route is confirmed against the requirement.
How to Choose the Right MS Eye Bolt
01
Load Direction
State whether the force acts in line with the shank or at an angle. Angular loading reduces capacity and usually calls for a collared pattern.
02
Thread Engagement
Confirm diameter, pitch, usable thread length and the receiving connection so engagement can be reviewed as one system.
03
Mounting Condition
Share the mounting surface, through-hole or tapped-hole arrangement and any washer or nut requirement.
04
Service Environment
Indoor, outdoor, moisture and corrosion exposure inform the finish, or a move to stainless steel.
Safety note
Lifting and load-bearing products must be selected against a confirmed working load limit, the applicable standard and the actual rigging arrangement. Never use a part beyond its marked or documented rating, and inspect before every use.
MS Eye Bolt vs SS Eye Bolt
Both share the same eye-and-thread form. The choice mainly follows the service environment and budget.

MS Eye Bolt FAQs
What is an MS eye bolt?
An MS eye bolt is a mild-steel fastener with a circular eye at one end and a threaded shank at the other. It creates an attachment point for suitable anchoring, suspension or handling arrangements when its size, installation and loading direction are correctly specified.
Which details are needed to quote an MS eye bolt?
Share the thread size and pitch, shank length, eye dimensions, required quantity, finish, intended application and any drawing, sample or standard reference. Load direction and working conditions should also be stated for handling-related enquiries.
Can the thread size and shank length be made to requirement?
The required thread form, diameter and shank length can be reviewed against your drawing or dimensional brief. Availability and the final manufacturing route are confirmed during technical review.
What is the difference between a collared and a plain eye bolt?
A collared eye bolt has a shoulder that seats against the mounting surface, which helps it resist angular loads when fully tightened. A plain eye bolt has no shoulder and is intended mainly for loads acting in line with the shank.
Can an MS eye bolt be used for lifting?
Suitability for lifting cannot be decided from appearance alone. The eye-bolt type, dimensions, load direction, installation, working load requirement and applicable standard must all be confirmed before selection.
Do you accept drawing-based or sample-based enquiries?
Yes. A dimensioned drawing is preferred, while a sample or clear dimensional schedule can also start the review. Final supply details are confirmed in the quotation before production.
