Inside the plant
Manufactured in our own plant
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
01
Cold heading
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
02
Thread rolling
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
03
Heat treatment
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
04
Surface treatment
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
Frequently Asked Questions
Which Allen key fits M24 Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 037)?
The hex-socket size for each row of Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 037) is shown in the spec table — use the matching Allen / hex key. An ISO 2936 set covers every size on this page.
How do I avoid stripping the socket on M24 Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 037)?
Fully seat the key in the socket, choose ball-end keys only for low-torque finishing work, and prefer a T-handle key when feel matters. For production use a torque-controlled driver.
What is the coarse-thread pitch of M24 for Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 037)?
For M24 the standard coarse pitch is 3 mm — this is the value used for Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 037).
What torque do M24 class 8.8 Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 037) take?
A dry M24 class 8.8 joint takes about 710 Nm (≈ 1000 Nm for 10.9, ≈ 1200 Nm for 12.9). Confirm against your joint design; lubrication reduces these values.
