10-Pack Stainless Steel Cotter Pins
This 10-pack supplies 3/16" by 1-1/2" split pins made from 18-8 stainless steel for corrosion-resistant fastening. Each pin inserts through a drilled hole and the tines are bent to lock assemblies in place. The hardware suits automotive, marine and general mechanical repairs where a removable yet secure fastener is required. The pack delivers ten identical pieces for multiple jobs or spares.
Mechanics needing split-pin retainers
Technicians securing clevis pins, castle nuts or drilled shafts will find the diameter and length compatible with common automotive and light-industrial hardware. Builders requiring larger diameters, longer lengths or non-stainless materials should look at other fastener selections because this pack only contains the stated size and alloy. The quantity suits occasional maintenance rather than high-volume production lines.
Consistent hold under vibration
The 18-8 stainless construction resists rust so the pin retains its spring tension during extended exposure to moisture and road salt. Once the tines are spread, the pin resists backing out under cyclic loads without the need for tools or thread-locking compounds. The simple bent-tine design provides a visible, inspectable lock that does not rely on friction alone.

Questions about this item
What size cotter pin hole do these 3/16" pins fit?
These 3/16 inch diameter pins are designed for matching 3/16 inch holes in castle nuts or drilled shafts.
Will the 18-8 stainless steel resist corrosion on older mild-steel brackets?
The 18-8 stainless material provides corrosion resistance, though contact with dissimilar metals in wet conditions may cause galvanic corrosion on the steel.
How can I confirm the pin is locked after spreading the tines?
After insertion, bend both tines outward fully; the pin should sit flush with the nut slot and resist pulling out by hand.
