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
What is the coarse-thread pitch of M30 for Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 036)?
For M30 the standard coarse pitch is 3.5 mm — this is the value used for Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 036).
What torque do M30 class 8.8 Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 036) take?
A dry M30 class 8.8 joint takes about 1400 Nm (≈ 2000 Nm for 10.9, ≈ 2400 Nm for 12.9). Confirm against your joint design; lubrication reduces these values.
What clearance and tapping drill suit M30?
Use a 33 mm clearance hole (ISO 273 medium) for through-fixing, or a 26.5 mm tapping drill for a coarse M30 thread.
Should M30 Lifting Eye Bolt — GB/T 825 / DIN 580 (Series 036) be tightened by torque or by angle?
For critical structural joints at M30, angle-controlled or stretch-controlled tightening is more repeatable than pure torque — the friction scatter at large diameters can dominate the torque signal.
