Pins

Dowel pins are precision-machined cylindrical pins used for accurate alignment of mechanical components. They ensure that assembled parts maintain exact positional accuracy before final fastening or during repeated assembly cycles.

Engineering characteristics:

Tight tolerance fit for high positioning accuracy

High shear resistance for structural stability

Suitable for permanent or semi-permanent assemblies

Typical applications:
Mold systems/tooling fixtures/precision machinery alignment.

Cotter pins are split wire fasteners used to prevent loosening of mechanical joints under vibration or movement.

Engineering characteristics:

Simple mechanical locking structure

High resistance to vibration loosening

Low-cost safety retention solution

Typical applications:
Automotive systems / agricultural machinery/linkage locking systems

Clevis pins are designed for hinged connections where controlled rotation is required. They are commonly used with cotter pins or retaining clips to secure axial position while allowing rotational movement.

Engineering characteristics:

High shear load capacity

Enables rotational joint movement

Reusable connection system

Typical applications:
Hydraulic cylinders / mechanical linkages / industrial equipment joints

Spring pins are hollow cylindrical fasteners that compress during installation and exert continuous radial pressure inside the hole.

Engineering characteristics:

Constant radial force retention

Shock and vibration resistance

No additional locking components required

Typical applications:
Automotive assemblies/machinery systems / dynamic mechanical structures

Specialty pins are engineered for specific industrial functions and installation conditions.

Common types include:

Taper pins for precise interference alignment

Grooved pins for enhanced retention strength

Hitch pins for quick-release systems

Retaining pins for removable assemblies
