Grease Fitting – 5/16″ Straight Drive Type, 9/16″ Overall Length

The 5/16″ straight drive-type grease fitting is designed for applications where threaded fittings cannot be used. Instead of screwing into a tapped hole, this fitting is driven into an appropriately sized drilled hole, creating a secure and leak-resistant press-fit connection. Made of durable steel, it provides reliable lubrication access points for bearings, housings, and machinery components. This fitting allows standard grease guns to service lubrication points quickly and effectively.
