Product Description
M6 x 0.75 Grade 8.8 Yellow Zinc Metric Fine Hexagon Head Set Screws
M6 x 0.75 x 25mm fully threaded hexagon head set screws manufactured from property class 8.8 high-tensile steel with a yellow zinc-plated finish. The 0.75mm pitch is finer than the standard M6 coarse thread and is intended for components specifically threaded M6 x 0.75.
These DIN 961-pattern fasteners feature a conventional external hexagon head and a thread extending along the usable shank. They are available in pack quantities from 5 to 1,000.

- Yellow zinc-plated finish
- Fully threaded set-screw construction
- External hexagon head
- Approximately 10mm spanner size
- Listed as DIN 961 pattern
- Available in packs from 5 to 1,000
Product Specifications
| Thread Size | Thread Pitch | Length | Width Across Flats | Head Height |
|---|---|---|---|---|
| M6 | 0.75mm | 25mm | Approximately 10mm | Approximately 4mm |
Fastener length is measured from beneath the hexagon head to the end of the threaded section. Head dimensions are nominal DIN-pattern values and should be confirmed if critical to the assembly.
Standards Information
This product is listed as a DIN 961 fully threaded hexagon head screw with an M6 x 0.75 metric fine thread.
Metric Fine Thread Identification
A standard M6 coarse-thread fastener normally has a 1.0mm pitch. This product instead has a 0.75mm fine pitch and will not fit an M6 x 1.0 nut or tapped hole.
| Thread | Pitch | Compatibility |
|---|---|---|
| M6 coarse | 1.0mm | Not compatible with this product |
| M6 fine | 0.75mm | Correct matching thread |
Check the thread with a pitch gauge or confirm the equipment manufacturer’s specification before ordering. Do not rely on the 6mm outside diameter alone.
Yellow Zinc-Plated Finish
The yellow zinc-plated finish provides greater resistance to surface corrosion than untreated steel and gives the fastener its characteristic yellow or gold appearance. Colour and shade may vary between manufacturing batches.
Zinc plating is generally suitable for indoor, automotive and moderately exposed applications. It should not be treated as equivalent to stainless steel or hot-dip galvanising in marine or highly corrosive environments.
Typical Applications
- Automotive and motorcycle components
- Small engines and mechanical equipment
- Precision machinery and instrumentation
- Hydraulic and pneumatic components
- Machine guards, brackets and fittings
- Repair of equipment originally using M6 x 0.75 threads
- Engineering and restoration projects
Installation Advice
Confirm that the mating nut or tapped component has an M6 x 0.75 thread. Attempting to install this screw into an M6 x 1.0 coarse thread can damage both components.
Install using a suitable 10mm spanner or socket. Tightening torque depends on the joint design, mating-thread strength, lubrication, coating and required clamp load. Follow the equipment manufacturer’s specified torque for safety-critical assemblies.
