Key Features
- OEM Thread and Grade Specification — Manufactured to the exact 3/8-16 thread pitch and 2-inch shank length specified by Husqvarna, so the bolt engages correctly without over-stressing the receiving threads.
- Broad Cross-Family Compatibility — A single part number serves multiple Husqvarna construction equipment families, including MS510 and MS510G tile and masonry saws, the Pro65G floor saw, and S22B and S22H dust and slurry units.
- Drop-In Replacement — Matches the original fastener's head style, drive type, and bearing surface, allowing direct installation without reworking the mounting bore or hardware.
- Structural Integrity Restored — A correctly torqued OEM bolt maintains the clamping force needed to keep guards, panels, and assemblies securely located during operation — a worn or incorrect bolt can allow critical components to shift or loosen.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts program, ensuring the bolt meets the same material and finish standards as the hardware installed at the factory.
A bolt of this size and thread specification is a structural fastener used to clamp assemblies, guards, or component housings together throughout Husqvarna construction equipment. It works by converting applied torque into clamping force that holds mating parts firmly in position during operation. When a bolt stretches, strips, or breaks, the assembly it secures can shift, vibrate loose, or fail to meet safety alignment requirements — replacing it promptly with the correct OEM fastener restores the intended clamping load and keeps the machine operating as designed.
