1/4" x 2-1/2" Standard duty release pins are ideal for basic holding and removal applications that don't require a positive locking ball feature. Constructed of corrosion resistant formed 304 stainless steel, these quick release pins are activated by a push or pull motion. The detent ball depresses and springs up for "quick release" applications. This robust, durable design is suitable for repetitive-use applications. Ideal for anchor clevis fittings, hinge pins or to replace cotter pins where frequent removal is necessary. Includes split ring for attachment of optional lanyard.
