Dimensional data for (M14) Square Weld Nuts to DIN 928, 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.

Need square weld nuts in a size this table does not list?
This page covers (M14) square weld nuts. Thread size is the obvious variable and rarely the interesting one — height for clearance, across-flats for the tool already in the cell, and the locking feature for the vibration actually present. Made by cold heading or tapping.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Applications & Industries for (M14) Square Weld Nuts
What Square Weld Nuts are specified for, industry by industry. Stocked from M4 to (M16).
Industries that specify Square Weld Nuts
-
Enclosures
threads in thin sheet with no access behind.
-
Agricultural equipment
welded fixing points.
-
Automotive bodies
threaded points in panels and brackets.
-
Steel furniture
frames welded before painting.
-
Building services
Threaded rod, channel and suspension assemblies.
-
Machine building & OEM
The clamping counter-face on studs and bolts throughout an assembly.
Typical applications
- resisting spin with the square body
- replacing tapped holes that strip in sheet
- creating strong threads in thin sheet
- welding before paint so threads stay accessible
- locking an adjustment so it cannot drift
- joints re-torqued at a service interval
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 paint or plate over the thread before assembly; clean the thread or it will bind.
