Controlling dimensions to DIN 71412 / ISO 6392 (lubricating nipples), with tolerances and fit.
M6 X 1.0 Grease Nipples (DIN 71412) are dimensioned by DIN 71412 / ISO 6392 (lubricating nipples). The controlling dimensions, tolerance classes and assembly data are tabulated below.
Figures are nominal values from the governing standard. Confirm against the tolerance class for your application before machining or ordering.
Dimensional data for M6 X 1.0 Grease Nipples (DIN 71412) to DIN 71412 / ISO 6392 (lubricating nipples), with the installation notes for this type.
Values are taken from the governing standard rather than from a general machine-thread table, because this type is not selected on one.
| Thread | Head angle | Form | Notes |
|---|---|---|---|
| M6 x 1.0 | straight (form A) | DIN 71412 A | commonest small nipple |
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.
The form below follows the current technical drawing configuration. Change the drawing values above and the request details update automatically.
| Thread | Head angle | Form | Notes |
|---|---|---|---|
| M6 x 1.0 | straight (form A) | DIN 71412 A | commonest small nipple |
| M8 x 1.0 | straight (form A) | DIN 71412 A | general machinery |
| M8 x 1.25 | straight (form A) | DIN 71412 A | general machinery |
| M10 x 1.0 | straight (form A) | DIN 71412 A | general machinery |
| M10 x 1.0 | 45 degrees (form B) | DIN 71412 B | where a straight gun will not reach |
| M10 x 1.0 | 90 degrees (form C) | DIN 71412 C | tight or shrouded positions |
| R 1/8 in | straight (form A) | DIN 71412 A | tapered pipe thread |
| R 1/4 in | straight (form A) | DIN 71412 A | tapered pipe thread |
| 1/4-28 UNF | straight | inch series | imported and automotive equipment |

What Grease Nipples are specified for, industry by industry. Stocked from M6 x 1.0 to 1/4-28 UNF (screw size).
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
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.
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.
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.
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.
Grip ranges are highly application-dependent at M6 X 1.0. As a guide, choose a length that gives at least 1× the thread diameter engagement in the nut plus 2–3 thread pitches projecting.
For critical structural joints at M6 X 1.0, angle-controlled or stretch-controlled tightening is more repeatable than pure torque — the friction scatter at large diameters can dominate the torque signal.
