Product identity

The MIDWEST FASTENER 930186 pack supplies 150 zinc plated steel cotter pins for mechanics and hobbyists who secure drilled fasteners on vehicles, machinery or general fabrication jobs. Each pin splits into two tines that bend to lock nuts, bolts or clevis pins in place. The bulk quantity keeps workshops stocked for repetitive maintenance tasks.

Capacity and headroom

The 150 piece count covers extended service intervals on fleet vehicles or multiple project builds without reordering. Zinc plating resists surface corrosion during outdoor or under-chassis exposure. The pins suit light to medium shear loads typical of automotive linkages; they are not rated for high vibration or structural joints that demand a positive locking device such as a safety wire or castle nut combination.

Deciding specification

Diameter and length are fixed at 1/16 inch by 1/4 inch, so the pack only fits holes and fastener shanks matching those dimensions. Buyers needing larger diameters, longer grip lengths or stainless steel material must select a different part number.

Questions about this item

Can I use these 1/16" cotter pins with the castle nuts already on my older machinery?

These pins have a 1/16" diameter and 1/4" length; they will fit castle nuts drilled for that specific size.

How do I verify the 930186 cotter pins are installed correctly after bending the tines?

After insertion, bend both tines outward around the nut flats; the pin should hold the nut firmly against rotation with no visible gap.

What comes in the 150-count package and do I need any special tools to install them?

The box contains 150 zinc-plated steel cotter pins; installation requires only pliers to bend the tines, no other tools or parts are included.
