Grease Nipples (DIN 71412) — DIN 71412 / ISO 6392 (lubricating nipples)
replacing a nipple whose ball check no longer holds
fitting a cap where the nipple is exposed to dirt
choosing the head angle so a grease gun can actually reach it
matching the thread form — metric, tapered pipe or UNF
joining and sealing a fluid or air line
adapting between thread forms on a manifold
Service conditions to specify against
Marine and coastal
Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
Where to use something else
Do not fit a straight nipple where the gun cannot reach it; the point then goes ungreased, which is worse than having no nipple at all.
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.

Grease Nipples (DIN 71412) (DIN 71412 / ISO 6392 (lubricating nipples)) are a type of pipe & pneumatic fittings used across industrial assembly. Below is the complete size table together with material, standard and application guidance.
What Are Grease Nipples (DIN 71412)?
Grease Nipples (DIN 71412) are pipe & pneumatic fittings defined by DIN 71412 / ISO 6392 (lubricating nipples). They are selected by screw size and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.
Materials & Finishes
Common materials include carbon steel (typically zinc plated or hot-dip galvanized), hardened or case-hardened steel where wear matters, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, hardness where relevant, and the surface finish appropriate to your application and environment.
Specification Guides
Each size, material and standard of Grease Nipples (DIN 71412) has its own reference page with the figures for that one configuration.

Pricing
Grease Nipples (DIN 71412) are supplied to order. Pricing starts from approximately US$0.10 per piece for standard sizes in carbon steel; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.
Grease Nipples (DIN 71412) — DIN 71412 / ISO 6392 (lubricating nipples)
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.
