Product Description
M14 Metric Fine 12.9 Socket Cap Set Screws
These M14 metric fine socket cap set screws are manufactured from high-tensile property class 12.9 steel and supplied with a self-colour, unplated finish. They feature an M14 × 1.5 fine-pitch thread and are fully threaded along their available length.
The internal hexagon socket provides positive tool engagement and makes these screws suitable for assemblies where access around the fastener head is limited. The finer 1.5mm thread pitch provides more precise adjustment and a greater number of engaged threads than the standard M14 coarse pitch.

Installation Guidance
Confirm that the mating component has an M14 × 1.5 thread before installation, as these screws are not compatible with standard M14 coarse-thread components. Use a correctly fitting hex key and apply the tightening torque specified for the particular joint, lubrication condition and application.
Self-colour steel has no protective plated coating and offers limited resistance to corrosion. Apply a suitable protective coating, lubricant or corrosion inhibitor where the screws may encounter moisture or corrosive conditions.
Please note that published dimensions and specifications are intended as a guide. Confirm any safety-critical or application-critical requirements before ordering.
