Zhuocheng Huck Bolt with Aluminum Collar 6.4X50mm

Huck bolts work differently to threaded bolt & nut, as they are installed via an industrial tool that provides a permanent solution. This makes them ideal when seeking a vibration resistant fastener. Huck bolts are fundamentally a two-piece grooved pin and collar combo where the collar sits over the pin and is compressed into the grooves of the pin via a designated tool. The tool presses the softer material collar into the pin making the two-piece combo an integrated one-piece entity.

Huck bolts fasteners consist of two pieces: a grooved bolt and a collar. Place the Huck bolt pin in a pre-drilled hole. The pin diameter should match the hole size for a snug fit that prevents lateral movement that could weaken the joint.

Place the Huck bolt collar on the opposite side of the pinhead. The collar sits over the pin and will form a strong, lasting joint when the collar is swaged (compressed) into the grooves of the pin via a Huck gun, the tool presses the softer material collar into the pin making the two-pieces into a one-piece combo.  

In the initial phase of the installation process, the Huck gun engages & pulls on the pin, while the nose assembly is forced down the collar. Progressively the tool, compresses the collar into the grooves of the harder steel pin. The pin and swaged collar are now combined to maximise metal-on-metal contact so, unlike a nut and bolt, it cannot work loose. The tensile strength of the Huck bolt is dictated by the number of grooves that are filled.
