Eye Bolt Inspection & Certification in Saudi Arabia
An eye bolt is a threaded forged bolt with a ring at the top, screwed into a tapped hole in a motor, gearbox, machine or fabricated item to provide a lifting point. Collared (shouldered) eye bolts can take angular lifts only when correctly seated and derated, while plain dee or bow eye bolts are limited to straight in-line pulls. They are widely used for maintenance lifts in Saudi workshops and plants, and misuse is common because capacity falls sharply with sling angle and poor thread engagement, so an independent check removes the guesswork.
What we inspect on an eye bolt
- ✓Collar seated flat and square on the load surface, with no gap; poor seating is grounds for rejection
- ✓Thread condition, length of engagement and correct thread type and size in the tapped hole
- ✓Shank for bending, necking, stretching and thread damage
- ✓Eye for elongation, wear, cracks and distortion where the shackle or hook bears
- ✓Marking showing WLL, thread size and manufacturer, and whether the eye bolt is a collared or plain pattern
- ✓Corrosion and pitting, particularly in coastal and marine environments
- ✓Magnetic particle inspection of suspect eyes and the shoulder radii
- ✓Capacity checked against the actual sling angle and lifting plan, with angular lift derating applied
Common defects we find
- ✓Bent shank or stretched threads after side loading or overload
- ✓Thread damage or cross-threading from poor fitting
- ✓Collar not seating on the surface, often because the thread bottoms out in a shallow hole or a recess or spacer holds the collar off the face
- ✓Elongated or worn eye where a shackle or hook bears
- ✓Plain-pattern eye bolts used for angular lifts
Risks of operating uncertified
- ✓Shank failure or thread pull-out under angular load can drop the lifted component.
- ✓Using an eye bolt at an angle beyond the manufacturer's derating table can overload it far below its marked WLL.
- ✓Insufficient thread engagement or a poorly seated collar can make the eye bolt bend or strip during the lift.
Testing, standards & frequency
Load / performance test
Where required, a proof load test is typically carried out at around twice the working load limit on new or reconditioned eye bolts, along with magnetic particle inspection, depending on the standard and client; eye bolts fixed to equipment are normally checked by visual and dimensional examination.
Inspection interval
Typically checked before every lift by the user and examined at least annually when kept as lifting tackle, with more frequent checks where eye bolts are left fitted to equipment in service.

FAQs
Can I use a collared eye bolt for angled lifts?＋
Collared (shouldered) eye bolts can take angular loads only when they are fully seated and the capacity is reduced according to the manufacturer's angle table. Plain eye bolts must only be loaded in line with the shank.
How far should an eye bolt be screwed in?＋
Until the collar sits tight and flat on the surface, with the thread engagement the manufacturer specifies for that material. If the collar will not seat or the thread bottoms out, do not use it; choose a different size or lifting point.
