Superior stainless steel fasteners. Provide 360 degrees of bearing surface for maximum holding power without a groove!
Tinnerman Grooveless Retainer Rings press over studs, shafts, or any round shape from .046 to 2.00" diameter.G-R-R's become an integral part of the axial application, replacing snap or bearing rings, cotter pins, staking,swaging, spinning, heat forming, ultrasonics, coining, cementing, or upsetting...eliminating high-cost operations.
Designed without slots,or shears, G-R-R's will not "walk-off" or spring free. Low profile flat designs require a minimum of space. Wall dimensions as thin as .024" make them ideal for limited access locations. They need as little as .032" of shaft or stud extension for full anchor.
Quality stainless steel assures long life, corrosion resistance, minimal distortion, dry finish, eliminates heat treat, finish and handling operations and the extra costs they entail.
A full range of sizes has been developed on modular tooling. Virtually any unlisted size can be made that falls within the limits of the tools, for a one-time set up charge. Sizes beyond this range can be made but require tooling.
