A Grade 80 lifting screw point — a forged, quenched-and-tempered alloy-steel threaded lifting eye that screws into threaded holes on machinery, molds, and heavy components to provide a dedicated overhead lifting point — built for repeated rigging of tooling, dies, and equipment where a secure, screw-on attachment is needed instead of a permanent eyebolt.
The G80 lifting screw point pairs a forged swivel eye with a threaded alloy-steel shank, giving engineers a bolt-on lifting point that rotates to align itself with the load direction instead of bending under side pull. Forged from super alloy steel and quenched and tempered, it is individually proof tested to 2.5 times its working load limit with certification, rated to an ultimate load of 4 times the WLL, and passes 100% magnaflux crack detection. Available in metric thread sizes from M8 to M42, rated from 0.6 t to 15 t in line (0°) and 0.3 t to 10 t at 90°, it is built for moulds, tooling, machinery bases and heavy equipment that must be lifted and positioned from threaded fixing points.
It is a swivelling alternative to fixed eyebolts — the eye turns to follow the sling angle, which keeps load off the thread — so always select by the rated load for your actual lifting angle (0° in line or 90° side lift). See the specification table below to confirm which thread size and WLL matches your application.
Forged from high-strength alloy steel and heat-treated by quenching and tempering for excellent strength, durability, and load-bearing performance.
Each lifting point is individually proof tested to 2.5 times the Working Load Limit (WLL) with certification. The ultimate load capacity reaches 4 times the WLL, ensuring reliable safety performance.
Every unit undergoes 100% Magnaflux (magnetic particle) inspection to detect surface and near-surface cracks, ensuring consistent quality and structural reliability.
Available in M8–M42 sizes, with WLL ranging from 0.6–15T at 0° and supporting side loading applications at 90°. Powder-coated surface treatment provides durability and clear color identification.
Not every threaded lift point needs a swivelling, certified lifting point. Where a mould, a machine base or a piece of tooling is lifted and turned from a threaded fixing point — and the sling angle may swing side to side — a swivel lifting point does the job a fixed eyebolt cannot, because the eye rotates to follow the pull direction instead of bending. Forged from super alloy steel and quenched and tempered, it is individually proof tested to 2.5 times its working load limit with certification, rated to an ultimate load of 4 times the WLL, and 100% crack-tested by magnaflux — built for dependable repeated lifting from threaded points.
Which size fits your job? If your load hangs straight down from the bolt (0° in-line lift), use the in-line rating — from 0.6 t on M8 up to 15 t on M42. If the pull comes in sideways or at an angle, the eye swivels but the load must be derated to the 90° rating — from 0.3 t on M8 up to 10 t on M42. If you only need a simple fixed attachment point for straight vertical lifting, a standard fixed eyebolt is the simpler, more economical choice.

If the load hangs straight down and the sling angle never changes, a fixed eyebolt is the simpler choice; if the pull direction swings side to side, a swivel lifting point keeps load off the thread.
Choose from M8 up to M42 (item DEL8021-01 through DEL8021-12) to match the tapped hole or stud in your mould, machine base or tooling — note M30 is offered in both a 5 t and an 8 t version.
In-line (0°) lifting is rated from 0.6 t to 15 t; side (90°) lifting is derated to 0.3 t to 10 t — never apply the 0° rating to a side pull.
