Key Features
- UHMW Material Construction — Ultra-High-Molecular-Weight polyethylene delivers outstanding abrasion resistance and impact toughness, exactly what's needed for a bolt cap exposed to the demands of concrete cutting environments.
- Genuine OEM Component — Manufactured to Husqvarna's original specifications, ensuring the correct profile, thread sizing, and material grade — no guesswork on fitment or material compatibility.
- Broad Floor Saw Compatibility — Fits a wide range of Husqvarna walk-behind floor saws, including the FS4800D, FS5000D, FS7000D, FS8400D, and RS8500D series.
- Drop-In Replacement — Designed to seat directly onto the 5/8 bolt position as the original, requiring no reworking of surrounding hardware or mounting points.
- Protects Underlying Hardware — A properly fitted bolt cap shields the bolt head from concrete slurry, debris, and mechanical contact, helping maintain thread integrity and simplifying future maintenance.
A bolt cap serves as a protective cover for an exposed bolt head, guarding it against the abrasive slurry, aggregate, and mechanical wear common in concrete cutting operations. On a walk-behind floor saw, unprotected bolt heads can become clogged with hardened debris or suffer surface damage that makes later removal difficult. The UHMW construction of this cap resists both abrasion and chemical exposure, keeping the fastener beneath accessible and intact across the service life of the machine.
