Key Features
- OEM Material Grade — Manufactured to Husqvarna's exact material and dimensional specification, delivering the shear strength and retention force required for floor grinder and dust collector assemblies.
- Drop-In Replacement — Matches the original rivet's diameter, shank length, and head profile, so it installs directly into existing holes without rework or modification.
- Broad Fitment Coverage — Compatible with a wide range of HTC and PG series floor grinders — HTC280, HTC510, HTC450, PG280, PG400, PG450, PG510, PG510I, PG820 — plus the DC3300 dust collector.
- Structural Integrity Restored — A failed or missing rivet can cause panels, guards, or housings to shift during operation; replacing it promptly keeps assemblies securely fastened and the machine performing as designed.
- Guard and Enclosure Safety — Where this rivet secures protective covers or dust-containment panels, correct installation is essential to maintaining proper guarding and dust management during grinding operations.
A rivet is a permanent mechanical fastener used to join two or more components by deforming its tail end to clamp them together once installed. In floor grinders and dust collectors, rivets are commonly used to secure housings, guards, covers, and internal panels that must remain firmly in place under the vibration and load of continuous grinding work. When a rivet shears, loosens, or corrodes, the connected components can shift or separate, affecting machine stability, dust containment, and operator safety — making prompt replacement with the correct OEM part essential.
