The UnitedBuilt S26826MS hex capscrew is a 3/8-16 x 1-inch pump-service fastener. Use it at the matching capscrew positions on the specified pump assemblies, rather than substituting a screw based on diameter alone.
Thread pitch, length, and fastener position all matter during a pump repair. This listing is for the capscrew component, not a complete pump hardware set. The quantity needed for a repair depends on the assembly and which fastening positions are being serviced.
