Product Description
M16 x 1.5 Metric Fine 10.9 Grade Self Colour Steel Hex Flange Set Screws
High-tensile M16 metric fine hexagon flange set screws manufactured from property class 10.9 steel and supplied with a plain self colour finish. The integrated flange distributes the clamping load over a wider area and can remove the need for a separate flat washer in suitable applications.
These fasteners have an M16 x 1.5 fine-pitch right-hand thread and are described as set screws because the threaded section extends along the usable length beneath the head. They are suitable for machinery, automotive, engineering and equipment maintenance applications requiring a strong, compact flanged fastening.

The existing catalogue does not provide the head and flange measurements for the 50mm version. Please confirm these dimensions before ordering if they are critical to the application.
Property Class 10.9
Property class 10.9 provides substantially greater tensile and proof strength than general-purpose 8.8 steel fasteners. The mating nut or internally threaded component must have a compatible thread pitch and adequate strength for the intended joint.
Self Colour Finish
Self colour steel has no protective zinc coating and may develop surface corrosion when exposed to moisture. Apply a suitable protective coating, lubricant or corrosion-control treatment when the fasteners will be used in damp or exposed conditions.
Typical Applications
- Automotive and vehicle assemblies
- Machinery and industrial equipment
- Engine and transmission components
- Fabricated steel structures
- Agricultural and construction machinery
- Maintenance and repair work
Installation Information
Check that the mating component is threaded M16 x 1.5 before installation; standard coarse M16 threads normally use a different pitch and are not interchangeable. Tightening torque should be selected for the joint, lubrication, mating material and operating conditions rather than relying on a single universal value.
The listing does not confirm whether the underside of the flange is smooth or serrated. Please check before ordering where the flange-face design is important.
