The M10 size of Closed-End Round-Body Blind Rivet Nuts is dimensioned by Trade series (closed-end blind rivet nuts). The table below gives the dimensional row from the standard, followed by the drive and the installation notes for this type.
M10 Dimensional Row (Trade series (closed-end blind rivet nuts))
| Thread size | Pitch (mm) | Grip range (mm) | Installation hole (mm) | Head diameter (mm) | End | Material options |
|---|
| M10 | 1.5 | 1.0~3.5 | 13.1 | 17.0 | closed | zinc-plated steel / stainless steel / aluminum alloy |
Spanner & Drive for M10 Closed-End Round-Body Blind Rivet Nuts
Drive geometry for M10 Closed-End Round-Body Blind Rivet Nuts is given by the row above; match the tool to the listed values.
Tightening Torque for M10
| Class 8.8 (dry, ~µ 0.125) | ≈ 49 Nm |
|---|
| Class 10.9 (dry, ~µ 0.125) | ≈ 69 Nm |
|---|
| Class 12.9 (dry, ~µ 0.125) | ≈ 83 Nm |
|---|
Indicative dry-joint values. Lubrication can lower the required torque by 15–25%. Always confirm against the joint design, especially when going up a strength class.
Proof Load & Strength for M10
| Tensile stress area As (ISO 898-1) | 58 mm² |
|---|
| Proof load, class 8.8 | 34 kN |
|---|
| Proof load, class 10.9 | 48 kN |
|---|
| Proof load, class 12.9 | 56 kN |
|---|
| Min. ultimate tensile, class 8.8 | 46 kN |
|---|
Proof load = stress area × proof stress per ISO 898-1. Design joints so the working preload stays below the proof load of the selected class.
Mating Parts for M10
Pair M10 with the matching M10 bolt or screw, plus a M10 flat washer where required to distribute load on softer materials.
When to Step Up or Down from M10
When the joint preload approaches the proof load of M10 class 8.8, step up to M12 class 8.8 (or move to M10 class 10.9). When the joint is over-specified, M8 often saves weight and cost without losing the safety margin.
Applications & Industries for M10 Closed-End Round-Body Blind Rivet Nuts
What Closed-End Round-Body Blind Rivet Nuts are specified for, industry by industry. Stocked from M4 to M10.
Industries that specify Closed-End Round-Body Blind Rivet Nuts
-
Outdoor enclosures
Cover and bracket attachment points exposed to water and dirt.
-
HVAC fabrication
Panel hardware installed after the duct or enclosure has been formed.
-
Refrigeration equipment
Sealed threaded mounting points in formed panels and closed housings.
-
Vehicle bodywork
Blind threads in rails and box sections where the cavity must stay closed.
-
Automotive & transport
Vibration-prone joints where the locking type is specified on the drawing.
-
Maintenance & MRO
Replacements matched to the existing bolt class, thread and finish.
Typical applications
- forming the blind bulb within the specified grip range
- choosing steel, stainless steel or aluminum for the service environment
- adding a sealed internal thread from the front face of a panel
- keeping water and debris out of a closed section behind the insert
- 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 drill to the thread minor diameter; the installation hole is set by the body and forming requirements.
