Washers / Dowel Pin / Split Pin / Circlip

Washers, dowel pins, and split pins are essential mechanical fasteners used across various industries to ensure secure and precise assemblies.

Washers are thin, flat discs placed under nuts or bolts to distribute load, prevent surface damage, reduce vibration, and prevent corrosion. Common types include flat washers, spring washers, and lock washers, each serving specific functions in mechanical and structural applications.

Dowel Pins are cylindrical rods used to align and join two components precisely. They come in solid, spring, and taper forms, with applications ranging from woodworking to machinery assembly. Standard sizes conform to IS 6689-2003 and IS 6688-2005.

Split Pins (also known as cotter pins) are metal fasteners with two tines that are bent during installation to secure other fasteners, such as clevis pins or castellated nuts. They are commonly used to prevent accidental detachment due to vibration or other movements.

Together, these fasteners play a crucial role in ensuring the integrity and longevity of mechanical assemblies in various applications.
