Benefits
#
The 2.5mm socket head cap screw addresses fastening requirements where high clamp load and confined-space installation are simultaneous requirements. Unlike hex bolts, the internal hex socket eliminates the need for external wrench clearance on both sides of the joint. The cylindrical head provides full loadability, enabling designers to utilise the complete load capacity of property class 12.9 alloy steel. Deep socket engagement allows high installation torque without cam-out. This diameter serves precision machinery, instrumentation, and small mechanism assemblies.
Common Applications
#
M2.5 socket head cap screws are specified for high-load confined-space fastening:
- Machine tool construction and CNC equipment
- Automotive engine and transmission assemblies
- Mold and die construction
- Hydraulic and pneumatic cylinder mounting
- Industrial gearbox assembly
