| Nypatch® | Rulands Nypatch® vibration resistant feature is a proprietary process that involves depositing a 360 degree coating of Nylon on several threads of the socket head cap screw. This coating reduces vibration which can cause threads to loosen, and reduces galling of the screw threads in stainless steel couplings. |
