Product Description
M14 × 1.5 Metric Fine Grade 12.9 Self Colour Socket Cap Bolts With Shank
High-strength M14 × 1.5 socket head cap bolts manufactured from property class 12.9 steel with a self-colour, unplated finish. These part-threaded fasteners combine a metric fine thread with an unthreaded shank for demanding machinery, automotive, tooling and engineering assemblies.

- Construction: Part threaded with an unthreaded shank
- Available lengths: 60mm, 80mm and 100mm
Check the pitch before ordering: these bolts have an M14 × 1.5 fine thread. They are not compatible with the standard M14 × 2 coarse thread or other M14 pitch variants. Use only with a matching M14 × 1.5 nut or tapped hole.
The thread and shank lengths reproduce the dimensions currently listed for the supplied variants. The different thread length shown for the 100mm bolt should be confirmed if grip length or thread engagement is critical.
Property Class 12.9
Property class 12.9 fasteners offer very high tensile strength for highly loaded engineering assemblies. Correct tightening torque and preload depend on lubrication, mating-thread strength, joint design and operating conditions. Use qualified engineering guidance for safety-critical applications.
Metric Fine Thread
The 1.5mm pitch provides more threads per unit length than the standard M14 × 2 coarse thread. Fine threads can provide controlled adjustment and are commonly used where an existing assembly specifically requires this pitch. They should not be substituted for another thread without confirming the joint design.
Self-Colour Finish
Self-colour steel is unplated and offers little inherent resistance to corrosion. Store these bolts in dry conditions and consider protective oil, a suitable coating or a plated alternative where exposure to moisture is expected.
