Dimensional data for (M14) Low Cap (Acorn) Nuts to DIN 917, with the drive and 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.

Applications & Industries for (M14) Low Cap Nuts
The sectors that buy Low Cap Nuts to DIN 917, and the duty each one buys them for. Stocked from M4 to M36.
Industries that specify Low Cap Nuts
-
Playground equipment
covered thread ends for safety.
-
Handrails
neat finishing on fixings.
-
Machinery
covers over studs near moving parts.
-
Furniture
exposed bolt ends in low-clearance areas.
-
Maintenance & MRO
Replacements matched to the existing bolt class, thread and finish.
-
Building services
Threaded rod, channel and suspension assemblies.
Typical applications
- protecting people from sharp threads
- finishing visible bolted joints
- sealing a thread end against dirt
- covering thread ends in tight spaces
- joints re-torqued at a service interval
- completing a bolted joint on a stud, rod or bolt
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.
- High load
- Supplied in ISO 898-1 property classes, so the joint can be designed to a stated proof load and tightened to a calculated torque rather than by feel.
- Match the class
- A nut below the bolt property class strips before the bolt reaches its own limit — pair class 8 nuts with 8.8 bolts, class 10 with 10.9.
Where to use something else
- Do not use a low cap nut where the bolt projects further than its internal depth; the bolt will bottom out.
