The Husqvarna 505725801 Shoulder Bolt 1/4 x 3/4 Black Steel is a genuine OEM component designed for the SoffCut2500 and SoffCut5000 early entry saws. As a direct OEM replacement, this bolt matches the original hardware specification — correct diameter, shank length, and black steel construction — so it seats and functions exactly as the factory-installed fastener. DHS Equipment supplies this part to help keep your early entry saw operating at full capacity. Cross-reference part number 505725801 against your parts diagram to confirm fitment before ordering.
Key Features
- Genuine OEM Black Steel Construction — Manufactured to Husqvarna's original hardness and tensile specifications, ensuring the shoulder provides the correct bearing surface and clamping force for its application.
- Exact Dimensional Match — The 1/4 x 3/4 shoulder geometry installs directly into the original mounting position without modification, maintaining proper component alignment.
- Compatible with SoffCut2500 and SoffCut5000 — Purpose-built for these Husqvarna early entry concrete saws, eliminating guesswork when sourcing replacement hardware.
- Restored Mechanical Integrity — A correctly fitted shoulder bolt keeps mating components accurately positioned under load, preventing the looseness and misalignment that a worn or damaged fastener can cause.
- Verified OEM Part Number — Ordering by part number this part ensures you receive the correct Husqvarna-approved hardware for your machine.
A shoulder bolt differs from a standard hex bolt in that it features a precision-ground, unthreaded shank — the "shoulder" — that acts as a locating pin and bearing surface for rotating or sliding components. This shank carries the mechanical load and holds parts in exact alignment, while the threaded portion secures the assembly. When a shoulder bolt wears, corrodes, or fails, the components it locates can shift under vibration, causing accelerated wear on surrounding parts or loss of cutting accuracy. Replacing it with the correct OEM hardware restores the tight tolerances the machine depends on.
