Ring Lock Studs are used in structural assemblies, such as forgings, turbine engines, castings and machined components where a nut is the preferred retention component by design. Studs act as a renewable hardened fastener platform to prevent thread wear and as permanent locators for component assemblies.

Studs are manufactured in many sizes and thread configurations, allowing oversize stud ends to be used for component repair while still allowing the use of intended nut sizes. This eliminates the need for additional fasteners or assembly tools.

Processed to strict government requirements, PTP Ring Lock Studs withstand multiple assembly / disassembly cycles without appreciable wear, and are available with standard or Lok-thread designs to enhance fastener retention and security.

PTP Ring Locked Studs have a serrated collar and are installed in specially prepared, tapped holes in the parent material. Once installed to the proper depth, a serrated lock ring is driven over the serrated stud collar to complete the installation and prevent the stud from rotating or backing out.
