High Strength Anti-vibration Ring Groove Rivet and Shoulder Rivet with Custom CNC Machining

This product series covers ring groove rivets, shoulder rivets, and grooved connecting pins. The ring groove rivet (also called Huck bolt or swage lock pin) is a high-strength structural rivet. The annular grooves on the shank lock tightly with the collar after installation, providing outstanding anti-loosening and shock resistance. The shoulder rivet adopts an integrated step shoulder design for limit positioning and fixed-depth riveting. The grooved connecting pin is reserved with a groove for circlip assembly, used for movable connection and axial limiting. We support CNC precision machining and can customize according to drawings or samples for different assembly requirements.

1. Ring groove rivet: High clamping force, vibration-resistant, not easy to loosen, suitable for heavy-load connections.
2. Shoulder rivet: Step shoulder positioning, controlled riveting depth, uniform stress, convenient assembly.
3. Grooved connecting pin: Standard groove structure, matches with circlip for limiting, flexible rotation.
4. Multiple optional materials: Carbon steel, alloy steel, SUS304, SUS316 stainless steel.
5. Surface treatment: Zinc plating, nickel plating, black oxide, passivation, hot dip galvanizing.
6. Strict tolerance control: Stable batch quality; accepts non-standard size, groove position, and head shape customization.
7. Process: Cold forging + CNC finishing, high structural strength.

Widely used in engineering machinery, vehicle chassis, rail transit, containers, agricultural equipment, automation frames, furniture, toy assemblies, sheet metal connection, and vibration-prone structural parts. An ideal choice for occasions requiring stable long-term fastening and anti-loosening performance.
