Spring Cotter Pins AWTools 150 pcs mixed sizes AW18319

AWTools spring cotter pins, pack of 150 mixed sizes, provide a simple removable retaining solution for shafts, clevis pins and various fasteners. These spring-style cotter pins are formed from spring steel and designed to compress when inserted through drilled holes and expand to hold components in place under light to moderate loads. The mixed-size assortment covers common diameters and lengths used in repair, maintenance and small mechanical assemblies.

Advantages

The spring cotter pins offer reliable retention through spring tension without requiring threaded fasteners or additional locking components. Their spring steel construction combines flexibility and strength, enabling repeated installation and removal while maintaining shape. Supplied as a mixed-size assortment, the pack reduces the need to purchase multiple single-size sets and ensures quick access to an appropriate pin during repairs or assembly tasks.

Suitable for

• Securing clevis pins and shaft ends in light machinery
• Temporary or removable fastenings in maintenance and repair work
• D.I.Y. projects, garden equipment and small agricultural machinery
• Hobbyist and model construction requiring removable pivots

Key specifications

• Quantity: 150 pieces in mixed sizes
• Material: spring steel
• Style: double-loop/split spring cotter pin (curved profile to provide tension)
• Finish: raw or untreated metallic surface typical of spring steel
• Compatibility: for use with drilled holes in shafts and clevis pins of matching diameters

How to use

Select a cotter pin from the assortment that matches the hole diameter of the shaft or clevis pin. Insert the pin through the aligned hole until the curved sections pass through and the pin exerts spring tension to retain the component. For removal, compress the pin slightly as needed and pull it out using pliers. Ensure the pin seats fully and that the retained component is properly aligned before placing the assembly back into service.

Usage recommendations

Inspect pins for wear or deformation before reuse and replace any that show significant fatigue or corrosion. Choose a pin whose diameter closely matches the drilled hole to ensure correct spring engagement. For corrosive or wet environments, consider choosing corrosion-resistant retaining pins; for general repair and maintenance, keep replacement pins of common sizes available to minimize downtime.
