Huck Bolt M16 x 50 - Screen Rail Bolt | TSX Screen
The screen rail bolt (Huck-type lock bolt, M16 × 50 mm) is the fastener that clamps the screen rails and deck support beams to the vibrating screen body. On a vibrating screen a conventional bolt-and-nut connection works itself loose under continuous vibration — a lock bolt with a swaged collar does not. That is why OEM screen builders use this type of bolt for rail fixing, and why TSX Screen supplies it as a genuine spare part for coal preparation and mineral processing screens.

Why a Lock Bolt Instead of a Normal Bolt
- Vibration-proof: the collar is swaged into the grooved pin, so the joint cannot back off — no re-tightening rounds, no loose rails knocking the deck.
- Consistent clamp force: installation is controlled by the collar swage, not by an operator's feel with a torque wrench.
- Galvanized body: resists the wet, slurry-laden environment of dewatering and desliming screens.
Applications
- Fixing polyurethane screen rails to deck support beams
- Cross member and longitudinal beam connections on vibrating screen bodies
- Scraper mounting on discharge and spray systems
- Recommended for screens fitted with our polyurethane screen panels
FAQ
What is a Huck bolt?
A Huck-type lock bolt is a two-part fastener: a grooved pin and a swage collar. Pulling the pin swages the collar into its grooves, creating a permanent, vibration-resistant clamp. “Huck bolt” is the common industry name for this fastening system.
