Product Description
M14 Grade 12.9 Self Colour Socket Cap Bolts With Shank – DIN 912
M14 Grade 12.9 high tensile steel socket cap bolts with a self colour finish. These DIN 912 bolts feature a cylindrical head, internal hexagon drive and a partially threaded body with an unthreaded shank.
The standard M14 × 2mm metric coarse thread suits matching nuts or tapped holes. A 12mm Allen key or hex bit is required for installation.

Length and Thread Coverage
Bolt length is measured from beneath the cap head to the tip. These bolts have an unthreaded shank; the threaded and plain lengths depend on the selected bolt length. Check these dimensions where the thread runout position is critical to the assembly.
Key Features
- Grade 12.9 high tensile steel construction.
- Part-threaded body with an unthreaded shank.
- Standard M14 coarse thread with a 2mm pitch.
- 12mm internal hexagon drive.
- Cylindrical cap head for installation with axial tool access.
- Self colour finish.
Typical Applications
Machine building, tooling, equipment assembly and engineering repairs where M14 Grade 12.9 socket cap bolts with an unthreaded shank are specified.
Installation
Match the diameter and pitch to the mating thread. Select a length that provides suitable engagement and allows the joint to clamp fully without the nut or tapped hole binding on the unthreaded shank. Fully engage the 12mm hex key or bit and tighten to the torque specified for the assembly.
Ordering
Select the required bolt length and pack quantity from the available options before adding to your basket.
