The load pin and retaining pin are the components most often lost or damaged on a clevis fitting. The retaining pin in particular is small, easily dropped, and absolutely necessary — without it the load pin can work out under vibration.
One condition, and it matters. A replacement part restores a fitting that is otherwise serviceable. It does not rescue one that has been overloaded. Before fitting, check the body against its wear limits — throat opening, section diameter, distortion, cracking. If any of those fail, the fitting is scrap regardless of how good the new part is.
Use genuine manufacturer parts only. A fitting repaired with a non-original component is outside its certification, and the certificate is what makes it a lifting accessory rather than a piece of steel.
Key Features
- Restores rather than replaces: A serviceable fitting with a worn part is a repair, not a scrap
- Genuine manufacturer part: Keeps the fitting within its certification — a non-original part voids it
- Suits Grade 8 clevis fittings: Check the size against the fitting before ordering
- Fit only to a sound body: Check throat opening, section diameter, distortion and cracking first
- Considerably cheaper than a new fitting: Which is the point, on a fleet of any size
- Record the repair: A replaced component should appear in the equipment record

Replacement Part | Genuine Manufacturer Component | Fit Only to a Serviceable Body
A genuine manufacturer replacement component. Fitting a non-original part places the lifting accessory outside its certification. Replacement parts restore a serviceable fitting; they do not rescue one that has failed its wear criteria. Under LOLER 1998, the repaired fitting remains subject to thorough examination by a competent person at intervals not exceeding 12 months, and the repair should be recorded.
Suitable Applications
Held as stores stock by anyone running a fleet of chain slings. On a large assembly fleet, catches and pins are the highest-turnover consumables — they are small, exposed and easily damaged, while the hook bodies themselves last for years. Keeping a stock of replacement parts is what keeps a fleet in service without a stream of scrapped fittings.
More About This Product
Shackles are the most-handled component in any lifting operation, and that is precisely why they wear out first. A sling gets rigged and derigged; a shackle gets rigged, derigged, dropped, driven over, thrown into a box and picked up by whoever needs one. Most lifting gear fails from a single overload; shackles fail from accumulated inattention.
The grade markings matter more than most people realise. A Grade 6 high tensile shackle to BS EN 13889 and a Grade 8 alloy shackle look similar and share the same body shape, but the alloy version carries considerably more at the same size. Once a shackle is in a box with fifty others, the only way to tell them apart is the marking — which is why an unmarked shackle has to be scrapped no matter how good it looks.
Understanding the Load Path
A shackle has two distinct load-bearing elements and they do different jobs. The bow takes the sling; the pin takes the load. Reverse that — put the sling on the pin and the load on the bow — and two things happen. The sling bears on a smaller radius than it was designed for, and any movement in the sling starts to rotate the pin.
On a screw collar pin that rotation is the failure mechanism. A sling shifting under a settling load, or vibration transmitted from plant nearby, will slowly unscrew the pin over minutes or hours. It rarely happens quickly enough for anyone to see it happening.
The second consideration is angle. A shackle loaded in line with the pin carries its full rating. Loaded at an angle across the bow it carries substantially less, and published derating tables cover a limited range of angles — beyond that range no figure is published because none applies. On a multi-leg sling every leg is at an angle by definition, which is why the bow shackle exists and why putting a multi-leg sling into a dee shackle is a genuine mistake rather than a preference.
How to Use
- Check the fitting body first: Throat opening, section diameter, distortion, cracking. If it fails any of these, it is scrap.
- Match the part to the fitting size: Kits are sized to the fitting and are not interchangeable.
- Use genuine parts only: A non-original component places the fitting outside its certification.
- Fit per the manufacturer’s instructions: Particularly the retaining components, which are what stop the load pin migrating.
- Test the repaired fitting: Confirm the catch or mechanism operates correctly before returning it to service.
- Record the repair: A replaced component should appear in the equipment record.
Warning: A replacement part restores a serviceable fitting. It does not rescue one that has been overloaded. Check the body against its wear limits first — a new catch on a hook with an opened throat is a fitting that will fail anyway.
Safety Information
- Fit only to a fitting that passes its wear criteria.
- Use genuine manufacturer parts only.
- Match the part to the fitting size.
- Fit per the manufacturer’s instructions.
- Test the repaired fitting before returning it to service.
- Record the repair in the equipment record.
- The repaired fitting remains subject to thorough examination at intervals not exceeding 12 months under LOLER 1998.
Inspection and Maintenance
Inspect the repaired fitting as a whole, not just the new part. Confirm the replacement operates correctly — a catch that springs closed against the nose with no gap, a locking mechanism that locks positively and releases cleanly, a pin that seats fully with its retaining component fitted. Then check the body itself: throat opening against original dimensions, section diameter at the bearing points, and any distortion or cracking. Record the repair.

Frequently Asked Questions
Q: Can I fit a non-original part?
No. A lifting accessory repaired with a non-original component is outside its certification, and the certificate is what makes it a lifting accessory rather than a piece of steel.
Q: When is a fitting scrap rather than repairable?
When the body fails its wear criteria — throat opening beyond tolerance, section diameter worn beyond the manufacturer’s stated limit, any distortion or cracking. A new part does not rescue an overloaded body.
Q: Do I need to recertify after a repair?
The fitting remains subject to thorough examination at intervals not exceeding 12 months. Record the repair, and if in doubt about the fitting’s condition, have it examined before returning it to service.
Q: How many should I stock?
On a fleet of any size, catches and pins are the highest-turnover consumables — small, exposed and easily lost, while the hook bodies last years. Most operations hold a spread across their common sizes.
