Controlling dimensions to DIN 580, with working load limit.

M12 Eye Bolts dimensions to DIN 580: coarse thread pitch 1.75 mm.

Coarse thread pitch: 1.75 mm

Figures are nominal values from the governing standard. Confirm against the tolerance class for your application before machining or ordering.

Dimensional data for M12 Eye Bolts to DIN 580, with the rated working load limit and the notes for safe installation. Values are taken from the governing standard rather than from a general machine-thread table, because this type is not selected on one.

Common Applications for M12 Eye Bolts

M12 Eye Bolts are commonly specified for medium-duty structural connections, automotive sub-frames and equipment chassis.

Mating Parts for M12

For M12, pair with a M12 hex nut (ISO 4032 / DIN 934) and, where used, a M12 flat washer (ISO 7089 / DIN 125A) under the head and under the nut.

Technical Drawing

Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

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 clearance and tapping drill suit M12?

Use a 13.5 mm clearance hole (ISO 273 medium) for through-fixing, or a 10.2 mm tapping drill for a coarse M12 thread.

What is the coarse-thread pitch of M12 for Eye Bolts?

For M12 the standard coarse pitch is 1.75 mm — this is the value used for Eye Bolts.

What torque do M12 class 8.8 Eye Bolts take?

A dry M12 class 8.8 joint takes about 85 Nm (≈ 120 Nm for 10.9, ≈ 145 Nm for 12.9). Confirm against your joint design; lubrication reduces these values.
