DIN 41652 — Scope
The table below lists the dimensions catalogued for jack screws for d-sub connectors under DIN 41652. The scope of DIN 41652 itself is not summarised here — where a figure matters, confirm it against the published document.
Tolerance & Product Grades
Product grade is a concept from dimensional fastener standards and does not apply to DIN 41652. Tolerances for this part are the limits shown against each dimension in the table.
Dimensions Specified by DIN 41652
| Male thread | Female thread | Across flats s (mm) | Overall length L (mm) | Male thread length (mm) | Material | Finish |
|---|
| M3 | #4-40 UNC | 5.0 | 8.0 | 4.0 | Brass | Nickel plated |
| M3 | #4-40 UNC | 5.0 | 11.5 | 4.5 | Brass | Nickel plated |
| M3 | M3 | 5.0 | 11.5 | 4.5 | Steel | Zinc plated |
| #4-40 | #4-40 UNC | 5.0 | 9.5 | 4.0 | Brass | Nickel plated |
| M3.5 | M3 | 5.5 | 14.0 | 5.0 | Stainless (A2) | Passivated |
Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Jack Screws for D-Sub Connectors page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
A complete specification for jack screws for d-sub connectors normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. DIN 41652 is one of them, not all of them.
Custom manufacturing · Made to drawing
Need a screw to this standard in a non-standard size?
Parts built to DIN 41652 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down. Made by cold heading or warm forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Applications & Industries
Where Jack Screws for D-Sub Connectors are used, and what decides the specification in each case. Stocked from M3 to M3.5.
Industries that specify Jack Screws for D-Sub Connectors
-
Instrumentation & control panels
Securing D-sub connector shells to a panel cut-out.
-
Industrial cabling
The fixed thread that a cable connector screws down onto.
-
Test & measurement
Rack and bench equipment interconnects.
-
Machine building & OEM
The default fastener on production equipment: covers, brackets, motor mounts and sub-assemblies tightened to a specified torque.
-
Automotive & transport
Chassis, driveline and body fixings that see vibration and are assembled to a controlled preload.
-
Steel fabrication
Bolted connections in frames, enclosures, walkways and weldments, on the bench and on site.
Typical applications
- holding a connector shell to a panel
- providing the female thread the mating cable screws pull against
- clamping two machined faces to a calculated preload
- bolting brackets, motors and gearboxes to a frame
- assemblies that are dismantled for service and re-torqued
- joints where the property class is stated on the drawing
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.
- Torque and preload
- The joint is designed around bolt tension, so lubrication, coating and the friction coefficient all change the torque figure — state them together.
Where to use something else
- Do not use a machine thread into unthreaded sheet or timber; use a tapping screw, rivet nut or insert made for that parent material.
